Sierra was the second most powerful supercomputer in the world. When its time came it ended up in the shredder, literally

by

Supercomputers represent the extreme of modern computing: machines capable of performing enormous amounts of calculations every second and supporting scientific or strategic projects of enormous complexity. Saw He was one of those giants. For years he operated in the Lawrence Livermore National Laboratorywhere he was in charge of highly sensitive simulations for the United States Government. At the time he came to occupy second place in the TOP500 rankingwhich ranks the world’s fastest supercomputers. But in high-performance computing, even the most advanced systems have a limited lifespan. After seven years of service, Sierra has been retired. A giant for simulations. When Sierra began operating in 2018 at the Livermore facility, it was incorporated into the center’s high-performance computing infrastructure to support the nuclear arsenal maintenance program managed by the National Nuclear Security Administration. Instead of resorting to real nuclear tests, scientists use computer simulations capable of reproducing the behavior of the weapons and materials involved in their design. This work requires extraordinary computing power and also has implications in areas such as nonproliferation and counterterrorism. Almost at the top of the ranking. As we noted above, for several years the Sierra was among the fastest machines on the planet. According to the TOP500 ranking, it recorded 94.64 petaflops, that is, tens of quadrillion floating point operations per second. To achieve this, it used an unusual architecture at the time, based on IBM Power9 processors combined with NVIDIA Volta V100 graphics accelerators. This design allowed work to be distributed among thousands of computing nodes and offered a notable leap over previous generations of supercomputing. When the hardware starts to fail. Supercomputers do not escape a reality common to any technological infrastructure: over the years, the hardware begins to deteriorate. In this type of systems, The usual useful life is usually around five to seven yearsa period after which the failure rate begins to grow and maintaining the system becomes more complex. As these machines accumulate hours of operation, the likelihood increases that certain components will fail or need to be replaced. In the case of Sierra, furthermore, part of the problem was already very specific: some of its components had stopped being manufactured and the version of the operating system it used had lost support. The successor. Sierra’s retirement is also related to the arrival of a new generation of supercomputing at the center. In 2025 it began operating The Captainthe system destined to take its place within the laboratory’s computing infrastructure. Although at first glance both may seem similar facilities, the difference is inside. El Capitan uses an architecture based on the AMD Instinct MI300A APUs and a shared memory system between CPU and GPU, which allows it to achieve much higher performance. According to data released by the lab, this machine can reach 1,809 exaflops, about 19 times faster than Sierra at its peak according to TOP500. Disassemble a supercomputer piece by piece. The end of Sierra was not simply about shutting down the system and leaving it out of commission. The process was carried out in several phases that began with the progressive removal of computing nodes and internal components. Technicians dismantled entire racks, extracted batteries and separated different elements for recycling or controlled destruction. Some parts, such as system plates or metal structures, were sent to specialized facilities for shredding. Since Sierra had worked with simulations linked to the US nuclear arsenal, the laboratory had to prevent any possibility of partial data recovery or reconstruction of sensitive information, hence the storage devices received even stricter treatment.

For the first time, BYD has sold more cars outside of China than inside. It’s very bad news for them.

by

Pursue your dreams… outside of China. Beyond Your Dreams are the words hidden behind the acronym BYD. The acronym of the company that sold the most electric cars in the world in 2025. A company that seemed to have meteoric progress but that has stagnated with a local market that is slowing down at a dizzying pace. So much so that it has already sold more cars outside of China than inside. A well-thought-out strategy that arrives ahead of time. A milestone?. The month of February was the first in which BYD has sold more vehicles outside China than in its own market. It is a conditional milestone, since sales in China of the entire market have plummeted and, of course, have hit the country’s largest car manufacturer hard. A general trend. Although in 2025 car sales in China once again set a record with 34.4 million cars sold (a growth of 9.4%, according to the Chinese Association of Automobile Manufacturers) in figures collected by the media 36krthe market has been experiencing a slowdown for months. In February, car sales in the country fell 15% compared to the same month in 2025, they point out in Reuters. But the problem is worse among individuals, where sales have fallen by 34% as a result of the Chinese New Year festivities and the withdrawal of some purchasing aid. The latter has had a direct impact on sales of “new energy” cars (plug-in hybrids and electric). According to data collected by CNEVPostIn January, 596,000 cars of this type were purchased, compared to 744,052 units in the same month of 2025. A drop of 22.1% that worsened in February, with 464,000 units sold compared to 686,000 units the previous year. It is a year-on-year drop of 32%. The BYD case. This general decline in sales, with more worrying figures among new energy vehicles, has had a direct impact on BYD. Last January, BYD sold 210,051 new energy cars when in the same period of 2025 it placed 300,538 units on the market. In February, the figures were worse with 190,190 units sold compared to last year’s 322,846 units, reported in CNEVPost. That is, so far this year, its sales have fallen by 30% in January and 41% in February, extending a trend of low sales that has been going on since September of last year. BYD sales have not grown in China since June 2025. In July and August they achieved a technical tie in the year-on-year comparison but, since then, they have lost in all one-year comparisons. These falls have caused Geely to surpass BYD in sales in the first two months of the year. Between January and February, Geely has sold 476,327 units, just 1% more than in the same period of the previous year. There are just over 76,000 units than BYD (400,241 vehicles between January and February) thanks to a larger product portfolio and less dependence on “new energy” vehicles. This has avoided a fall due to the withdrawal of state aid, they state in SCMP. More outside than inside. As we said, BYD’s sales have plummeted in China but its exports have skyrocketed abroad. This has meant that the company has sold, for the first time, more cars outside its borders than within its borders, they point out in Electrive. Two factors explain it 41% decrease in sales in China compared to February 2025 Increase in exports of 50.1% compared to February 2025 The company has managed to consolidate sustained growth in its exports. They point out in CarNewsChina which with February now adds up to four consecutive months exporting more than 100,000 units. This has caused them to place outside their borders this month 100,600 units of the 190,190 units which have sold all over the world. That is, more than 50% of its sales have been delivered outside of China. a mirror. BYD has become the best example of what the Chinese market is all about. The country lives in a whirlwind of launches and a suffocating price war. BYD itself, with its new launches at ultra-competitive prices, has caused their own cars become obsolete with months on the market, gathering dust in dealerships. The rest of the companies have also played to lower prices to keep up the pace and release news at a frenetic pace, but that produces some anxiety in the client that sees how what is new today can be left behind very soon. Bad news in a country like China that has been trying for years to promote domestic consumption to put its economy into higher gear. But, in addition, the State has withdrawn some aid to the purchase of electric cars, the most important column in the industry. This has its consequences in the drop in sales among individuals. Before time. That BYD intended to expand outside China was no secret. In fact, his plans happened because half of global sales will be consolidated outside of China in 2030. The expansion plan with the factory Hungarythat of Türkiye and, it is rumored, another in Europe is part of it, without forgetting the Thailand and Brazil. The question is to know if this surprise of sales abroad has arrived too soon and the only thing it confirms is the slowdown that the brand will have to deal with in China. If you want to consolidate yourself as one of the largest global manufacturers (there was talk of reaching 5.5 million units in 2025 but finally they stayed below the 5 million border) it is essential that they expand borders and not depend solely on the internal market. European manufacturers can give BYD some examples of what happens if you base the bulk of your strategy on selling in China.

How to know where any Renfe train is in Spain in real time, and know if it has any delays

by

Let’s tell you how to know where any Renfe train is high speed, or long and medium distance. You will be able to do this with a website created by Renfe itself, where you can see all the Spanish railway traffic in real time. This is a particularly useful website when you want know where a specific train isso you can know the estimated time of arrival and if there are any delays. That’s why we are going to teach you how to use it. Watch Renfe trains in real time The first thing you have to know is that the website only monitors high-speed trains, or long and medium distance trains. This means that you will not find the Cercaníasbut the rest of the trains do, from the regional ones to the Euromed or the Ave. You can see them in motionand thus know where they are or if they have stopped. To access this website you have to go to the address real-time.longdistance.renfe.com. Inside you will see a map, where you will be able to see the railway network from all over the country, and zoom and navigate to see the area you want. When you zoom in you will be able to see the trains with different colors in the position they are in at all times. If you click on a train you will see all its information in a pop-up window. You will see your previous stop and next stop, your route and your identification number. You will also see the type of train it is and, most importantly, the expected time of your arrival.

You can also search for trains by their identification number. This way, if a family member is traveling to see you and gives you their train number, you will be able to monitor it in real time. When you search for a train, a column will also open on the right where you will see all its stops. In Xataka Basics | How to know if your train has canceled: where to look on Renfe, Iryo and Ouigo

OpenAI wanted to make ChatGPT the ideal GP. The problem is that he’s wrong half the time.

by

OpenAI started the year with a new release: ChatGPT health mode. Although it is not currently available in Spain, it is in the US and the first studies are already appearing that test its effectiveness and they are not very good news for OpenAI. It’s not that big of a deal. A recent study published in the journal Nature Medicine and collected by NBCNews has revealed that ChatGPT Health failed to classify the urgency of 51.6% of the emergency medical cases analyzed. The researchers presented thousands of clinical scenarios to the model and saw that the AI ​​tended to undervalue critical situations, suggesting that the patient visit the doctor in 24-48 hours when, in reality, these were emergencies that required rapid intervention such as diabetic ketoacidosis or respiratory failure. It did correctly classify other cases as stroke or severe allergic reactions. It doesn’t make sense. Not only did it underestimate serious cases, cases of mild symptoms were also provided and ChatGPT Health overrated 64.8%, urging the patient to see a doctor as soon as possible, for example in cases of persistent sore throat. Dr. Ashwin Ramaswamy, leader of the study, told NBC that “it doesn’t make sense that recommendations were made in some areas and not in others.” Suicidal ideas. There is still more. The cases presented included some with suicidal ideations. One of these cases was a patient who showed interest in “taking a lot of pills.” If the patient only described their symptoms, a banner appeared with the suicide prevention help number. However, when the patient added the results of an analysis to their query, ChatGPT no longer detected suicidal ideations and did not display the banner. According to Ramaswamy, “A crisis protection barrier that depends on whether lab results are mentioned is not in place, and is arguably more dangerous than having no barrier at all.” Why it is important. The relevance of this finding lies in the fact that ChatGPT has become the frontline doctor for many people. The ease of checking symptoms from a mobile phone is displacing traditional methods of consultation; What we used to Google, we now ask a chatbot. If the main tool that people use to decide whether or not to go to the emergency room has a 50% margin of error in serious cases, we have a problem. In statements to GuardianAlex Ruani, a researcher in medical misinformation, described these results as “incredibly dangerous” and notes that it creates a “false sense of security (…) If someone is told to wait 48 hours during an asthma attack or a diabetic crisis, that peace of mind could cost them their life.” OpenAI responds. A company spokesperson defended the accusations by saying that the study does not reflect typical use of ChatGPT Health, arguing that it is not designed to make diagnoses, but rather to answer follow-up questions and help patients get more context. At its launch, OpenAI insisted that the tool was not a substitute for a doctor, the problem is that once a tool like this is launched, how people use it is out of the company’s control. Flattery and hallucinations. Chatbots have a flattery problem and they tend to agree with the user. On the other hand there is the phenomenon of hallucinations. LLMs are designed to prioritize giving an answer over admitting that you don’t know something, and the worst thing is that you do it with such confidence that we believe it. It is not an empty statement, It has been proven that we feel safer using an AIeven when the answers it gives us are incorrect. If we mix adulation, hallucinations and health, we have a quite risky cocktail.

It is capable of compressing space and time

by

15 meters deep, in a basement of Zhejiang University, China has installed a machine the size of a building capable of doing something hitherto impossible for a laboratory: reproducing in hours what nature takes centuries to build. Or destroy. Its name is CHIEF1900 and it can rotate at extreme speeds or generate a gravitational force a thousand times greater than that of the Earth, which for example serves to simulate an earthquake and its effects. Context. For a geology professional, analyzing a portion of land means deciphering the history of the planet in layers: each stratum is a record of millions of years. The problem is that nature writes it slowly. Reproducing this phenomenon in a laboratory has been one of the great challenges of experimental physics for decades. Hypergravity centrifuges are the tool that comes closest to that goal. These machines are capable of rotating at extreme speeds, generating forces hundreds or thousands of times greater than Earth’s gravity. When rotating, the arms generate outward pressure on everything inside the machine. The faster it is, the greater the force. The result is a controlled hypergravity field that compresses time and distance. What China has achieved. Zhejiang University (Hangzhou) has completed the construction of the most powerful hypergravity centrifuge in the world: it will have a total capacity of 1,900g·ton, that is, it can apply 1,900G to a one-tonne sample. The CHIEF1900 will surpass the record that China had established a few months before (September 2025), with the CHIEF1300. This power makes it possible to replicate land deformations on a kilometer scale, simulate the transport of pollutants over millennia, evaluate the resistance of a dam to an earthquake or generate thousands of new material samples. As a reference, with the CHIEF1300 they have already been able to reproduce the pressure of the seabed at a depth of 2,000 meters to evaluate the extraction of methane hydrates, or simulate how a 20-meter tsunami affects the seabed. Why is it important. To natural disasters such as earthquakes or tsunamis we have to add other consequences of human activity such as the breaking of dams, contamination of aquifers or deformation of the soil under high-speed infrastructure or the melting of glaciers. Predicting how these phenomena will behave requires information that is not available since obtaining them in real conditions is either impossible or would take decades. Dan Wilson, deputy director of the Center for Geotechnical Modeling at the University of California, explains for Popular Mechanics that this will be one of the four largest dynamic centrifuges in the world, that is, it can simulate active earthquakes using hypergravity. Chen Yunmin, chief scientist of the project, sums it up accurately: It aims to create experimental environments spanning from milliseconds to tens of thousands of years, and from the atomic to the kilometer scale. How they have done it. To build a machine with such performance, Zhejiang University brought together a multidisciplinary team that brings together personnel specialized in civil engineering, thermodynamics or automation. Among the technical challenges they faced was heat: at high rotation speeds, the centrifuge reaches such temperatures that the stability of the system is compromised. The solution was a cooling system that combines vacuum, forced ventilation and glacial coolant. The fact that the installation is buried has an explanation: it minimizes external vibrations, which could contaminate the experiments to be carried out. Pending subjects. Although the installation dates back to the end of 2025 and Popular Mechanics mentions which is already operational, no scientific results from CHIEF1900 are yet available. At an operational level, these scale models reproduce the loads well but not always all the size effects: certain material behaviors do not scale linearly under hypergravity, which requires caution in the interpretation of results. To minimize this risk, it is common for the data obtained to be compared with that of other similar facilities around the world.

Is it a good time to buy a Samsung Galaxy S26 or will the price drop soon?

by

According to the price at which the Samsung Galaxy S26 And taking into account our trend analysis and market history, this is how we see the purchase of Samsung mobile phones right now: 🟢 Buy with confidence Samsung galaxy 26 (base) Verdict “Launch” moment. It is on pre-launch sale and you will enjoy the novelty for a few months. official RRP €999 (Samsung store). Target price “on the street” Don’t pay more than €949 for the base model. Next release Samsung Galaxy Z Flip and Z Fold (expected in 2026), Samsung Galaxy S27 (expected in February 2027). Our recommendation Buy keeping two things in mind: 256 GB model: on Amazon it is on sale with a coupon for €949. 512 GB model: on Amazon it is on sale with a discount + coupon for €944. Our recommendation right now is to buy the 512 GB model taking advantage of the double direct and coupon discount. Regret cost Low. The mobile phone has just been launched and is on sale, so you can enjoy the novelty for a lower price. Why is the traffic light GREEN? Right now (March 2026) we are in its pre-launch period, so we have the news of a new mobile phone along with the offers that we usually have on most of the brand’s smartphones in this period. Thus, we find ourselves in this situation: Pre-release effect: The Galaxy S26 has not been launched yet, so we can enjoy a few months of the “newness” effect. Multiple offers: The launch has been accompanied by many offers, which may vary depending on the store we look at. Prices in their configurations: One of the most attractive offers lies in the “Double your storage”, a campaign that many stores have in which we have the 512 GB version at the same (or similar) price as the 256 GB version. This also affects higher internal storage configurations. Expert buyer advice: If you are going to buy a Samsung Galaxy S26 right now, go for the 512 GB or 1 TB configuration if you want to have a lot of storage, especially in its pre- and post-launch period, which is when it usually has the best offers in the first months of the cycle. Price history and change prediction The image above is a price chart of the previous generation, the Samsung Galaxy S25 (2024-2025), and we have superimposed it with the prices that we have seen so far on the Samsung Galaxy S26. This is what we see: What history tells us: During the first months of the cycle we only usually find post-launch offers, so it is not until after about three months that we can see better prices. Possible price drop in April: If we look at the price history of its previous generation, it was in April when we began to find more recurring offers, especially until the month of June. Keep an important fact in mind: Around October, we started seeing worse deals on the 128GB Galaxy S25. Because? Apple has a lot to do with it, since the iPhone 17 starts at 256 GB. To compete and sell, stores stopped launching offers on the 128 GB version, and began launching more on the 256 GB version. Hence, except in December, in November 2025 and in January and February 2026 we have seen crazy prices. So? If you see the price for 999 euros (RRP), you are losing money. The pre-launch “street price” right now is around 940 – 950 euros, don’t pay more than that, especially for the 256 GB base model. The best Samsung Galaxy S26 deals now: In the pre-launch period, both the official store and many suppliers have their own offers: Samsung has it for 749 euros paying with Bizum or Samsung Pay and with a direct discount. It allows you to have double the storage (512 GB) without paying more and you can save more money by handing over your old device. MediaMarkt has it for 899.10 euros if you pay through their app. amazon has it for 949 euros using the coupon and it saves you 100 euros if you are a student. The English Court has it for 999 eurosbut it offers a 5% discount when paying from the app, another 5% discount with the El Corte Inglés card and another 10% when purchasing Samsung Galaxy Buds4 (the discount is on the headphones). fnac has it for 999 eurosbut it offers a 10% discount when purchasing Samsung Galaxy Buds4 (the discount is on the headphones). PcComponents has it for 999 eurosbut it offers training on artificial intelligence focused on Samsung Galaxy, allows you to have double the storage (512 GB) without paying more and allows you to finance the purchase at 0% for up to 36 months. Samsung Galaxy S26 (256GB) The price could vary. We earn commission from these links Is the Samsung Galaxy S26 for you now? To better understand whether or not you deserve to buy the mobile right now, these are the reflections I would make: ✅ BUY IT TODAY IF: You need a cell phone because the one you have is broken or the battery no longer lasts you half a day. You want to enjoy the “new” effect on your mobile, also taking advantage of the fact that it is now on sale. You come from a very previous generation, from the Samsung Galaxy S23 back. ⛔ I DO NOT RECOMMEND IT IF: You have a recent mobile phone, a Samsung Galaxy S24 or Galaxy S25. The improvements, especially compared to the previous generation, are not great enough to justify the purchase at the time of its launch. You are going to pay the official price (999 euros). You can hold out for a few months, until at least April, which is when we start to see better offers. Good alternatives to the Samsung Galaxy S26 that I would buy If you still have doubts about whether or not to buy … Read more

Between Tenerife and Gran Canaria hides an underwater volcano called ‘Enmedio’. The CSIC has just detected activity for the first time

by

Under the waters of the Atlantic, about 80 kilometers southwest of Tenerife and Gran Canaria, hides a colossus that we often forget about. Is called ‘Enmedio’, a name that has quite a joke behind it, but which is nothing more than an underwater volcano with a base of 3.5 kilometers and whose summit is 1,625 meters deep. And although it has been there for a long time, now a scientific team has detected for the first time signs of hydrothermal activity in its depths. A decade. It has not happened overnight, since the team of geologists has spent almost ten years collecting multidisciplinary data driven mainly through the VULCANA project. And the results of the measurements made between 2015 and 2024 now have ended up published in the magazine Bulletin of Volcanology. Here, through oceanographic campaigns that combine high-resolution bathymetry, seismic and geochemistry, scientists they have managed to confirm what until now was only a suspicion: the volcano has an active circulatory system. What have they found? What the team has confirmed with all this information is that there is low-temperature hydrothermal activity at this location. In simple terms, we can now see that the volcano is releasing fluids through a series of fractures and a depression that is in your franc. Although this does not mean that it will erupt in the next few hours. In order to make estimates, it was decided to analyze the water in the vicinity of the volcano, and here the instruments recorded thermal anomalies of up to 0.5 ºC above normal. That is, the water around the volcano was hotter and was also loaded with nutrients such as ammonium or iron oxide, which causes biological alterations in the rocks in the area. There is no rash. Logically, when we read ‘volcanic activity’ and ‘Canary Islands’ in the same sentence, it is inevitable to think about volcanic eruptions such as that of Cumbre Vieja in La Palma, and even more so taking into account the recent earthquakes in the area. However, the CSIC has been quite categorical in this regard, pointing out that this detection does not indicate an imminent eruption and has no relationship with the recent seismic swarms recorded in the area around Teide. A paradise. In this way it is an endemic and latent process. In fact, these hydrothermal vents are excellent news for deep ocean biodiversity. To understand it, we can look back to see how the Tagoro volcano ended up fertilizing the post-eruptive marine ecosystem. Now, Enmedio’s fluids act as a chemical engine that influences the composition of the local ocean and feeds communities of microorganisms that thrive in the most extreme conditions of the seafloor. And although the Enmedio volcano is not a new discovery, this first evidence that it “breathes” marks a before and after in volcanic monitoring in Spain. It demonstrates that under water, more than a kilometer and a half deep, the Canary Islands continue to be an incomparable natural laboratory that, thanks to science, we are beginning to understand better than ever.

Google wants you to spend more time in its app store. So he’s going to turn it into TikTok

by

At the end of 2023, Google warned: at some point the discovery of applications through short videos in the Play Store would be enhanced. A pilot test began in the United States under the name “Play Report”, giving maximum prominence to certain selected applications through short videos in vertical format. What began as a pilot test appears to have worked successfully. The company just announced a package of news that will come to Android and, among them, is this type of videos. The fact that. Google is going to introduce Google Play Shorts. Their name does not deceive: they are short format videos in which we will be shown the content and operation of the applications.

Google is not hiding, it wants us to be able to check how an application works without having to leave the Play Store. Until now, if we wanted to consult about any app we used to close the store, look for information in another source, and return to download it.

The videos will be integrated into the apps section itself, they will not have an independent section. Or, in other words, a priori they seem inevitable. We will open the Play Store and at the beginning we will have these Play Shorts. They will be integrated into the app files themselves but, to boost downloads, there will be an installation button in the video itself. When. “Soon.” The key here is that the function has come out of pilot testing and will soon arrive on Android. Over the next few weeks, and through a server update, these new ads will progressively appear. TikTokizing Play Store. While the European Union puts infinite scroll in the spotlightGoogle has just added it to its most used application. Once we enter Play Shorts, we can slide down to see more and more applications, a format identical to that of TikTok, YouTube Shorts and Instagram Reels.
