US overtakes Chinese supercomputer to take top spot for fastest in the world

Published

on

After a semi-annual assessment measuring supercomputer computational speeds, US-built IBM machine “Summit” has toppled two Chinese competitors to take the lead as the fastest of its kind in the world. China’s Tianhe-2 and Sunway TaihuLight spent the last two years at the top of the SuperComputer TOP500 List, but this month Summit pulled ahead of both with a performance of 143.5 quadrillion operations per second, making it 65% more powerful than the next non-US supercomputer on the list. Out of the top ten machines ranked, five are in the United States.

The TOP500 project was established in 1993 to track and rank meaningful statistics for organizations to use in determining their needs with regard to high-performance computing (HPC). The benchmark test used to determine the rankings is called “Linpack”, which requires HPC systems to solve a specific set of linear equations using floating point arithmetic. To help quantify just how powerful the machines in the HPC category are, Summit is 1 million times more powerful than the fastest laptop with 250 petabytes of storage capacity.

Located at the Oak Ridge Leadership Computing Facility (OCLF) in Tennessee, the Summit supercomputer has an architecture purpose-built and optimized by IBM for artificial intelligence. While specialized, access to its technology isn’t exclusive to the machine’s developers. All components are available to any enterprise as part of IBM’s product line.

Summit was funded with part of a $258 million grant from the U.S. Department of Energy to help maintain US leadership in national security, manufacturing, industrial competitiveness, and energy and earth sciences. Summit’s “sister” computer, Sierra, was developed as part of the same Department of Energy commission and takes second place in the TOP500 list. This machine is located at Lawrence Livermore National Laboratory (LLNL) in California, and it boasts a computing speed of just under 95 quadrillion operations per second.

The HPC field overall provides computing power for advanced artificial intelligence along with massive data projects in business, medicine, science, and engineering. A recent competition hosted by the Association for Computing Machinery to recognize achievements in HPC, the Gordon Bell Prize, named five finalists that used Summit for advanced science research. The projects included, among others, an algorithm looking for genetic variations linked to complex traits and conditions such as opioid addiction, an AI simulation of earthquake physics in urban environments, and a deep neural network to identify extreme weather patterns from climate simulations. The winner of the competition will be named later this week at the 2018 International Conference for High Performance Computing, Networking, Storage, and Analysis in Dallas.

Tesla Cybertruck gets small change that makes a big difference

Tesla made a change to the Cybertruck, and nobody noticed. But to be fair, nobody could have, but it was revealed by the program’s lead engineer that it was aimed toward simplifying manufacturing through a minor change in casting.

After the Cybertruck was given a Top Safety Pick+ award by the Insurance Institute for Highway Safety (IIHS), for its reputation as the safest pickup on the market, some wondered what had changed about the vehicle.

Tesla Cybertruck earns IIHS Top Safety Pick+ award

Tesla makes changes to its vehicles routinely through Over-the-Air software updates, but aesthetic changes are relatively rare. Vehicles go through refreshes every few years, as the Model 3 and Model Y did earlier this year. However, the Cybertruck is one of the vehicles that has not changed much since its launch in late 2023, but it has gone through some minor changes.

Most recently, Wes Morrill, the Cybertruck program’s Lead Engineer, stated that the company had made a minor change to the casting of the all-electric pickup for manufacturing purposes. This change took place in April:

The change is among the most subtle that can be made, but it makes a massive difference in manufacturing efficiency, build quality, and scalability.

Morrill revealed Tesla’s internal testing showed no difference in crash testing results performed by the IIHS.

The 2025 Cybertruck received stellar ratings in each of the required testing scenarios and categories. The Top Safety Pick+ award is only given if it excels in rigorous crash tests. This requires ‘Good’ ratings in updated small and moderate overlap front, side, roof, and head restraints.

Additionally, it must have advanced front crash prevention in both day and night. Most importantly, the vehicle must have a ‘Good’ or ‘Acceptable’ headlights standard on all trims, with the “+ ” specifically demanding the toughest new updated moderate overlap test that checks rear-seat passenger protection alongside driver safety.

Tesla enters interesting situation with Full Self-Driving in California

Tesla has entered an interesting situation with its Full Self-Driving suite in California, as the State’s Department of Motor Vehicles had adopted an order for a suspension of the company’s sales license, but it immediately put it on hold.

The company has been granted a reprieve as the DMV is giving Tesla an opportunity to “remedy the situation.” After the suspension was recommended for 30 days as a penalty, the DMV said it would give Tesla 90 days to allow the company to come into compliance.

The DMV is accusing Tesla of misleading consumers by using words like Autopilot and Full Self-Driving on its advanced driver assistance (ADAS) features.

The State’s DMV Director, Steve Gordon, said that he hoped “Tesla will find a way to get these misleading statements corrected.” However, Tesla responded to the story on Tuesday, stating that this was a “consumer protection” order for the company using the term Autopilot.

It said “not one single customer came forward to say there’s a problem.” It added that “sales in California will continue uninterrupted.”

Tesla has used the terms Autopilot and Full Self-Driving for years, but has added the term “(Supervised)” to the end of the FSD suite, hoping to remedy some of the potential issues that regulators in various areas might have with the labeling of the program.

It might not be too long before Tesla stops catching flak for using the Full Self-Driving name to describe its platform.

Tesla Robotaxi goes driverless as Musk confirms Safety Monitor removal testing

The Robotaxi suite has continued to improve, and this week, vehicles were spotted in Austin without any occupants. CEO Elon Musk would later confirm that Tesla had started testing driverless rides in Austin, hoping to launch rides without any supervision by the end of the year.

Tesla stock closes at all-time high on heels of Robotaxi progress

Tesla stock (NASDAQ: TSLA) closed at an all-time high on Tuesday, jumping over 3 percent during the day and finishing at $489.88.

The price beats the previous record close, which was $479.86.

Shares have had a crazy year, dipping more than 40 percent from the start of the year. The stock then started to recover once again around late April, when its price started to climb back up from the low $200 level.

This week, Tesla started to climb toward its highest levels ever, as it was revealed on Sunday that the company was testing driverless Robotaxis in Austin. The spike in value pushed the company’s valuation to $1.63 trillion.

It is the seventh-most valuable company on the market currently, trailing Nvidia, Apple, Alphabet (Google), Microsoft, Amazon, and Meta.

Shares closed up $14.57 today, up over 3 percent.

The stock has gone through a lot this year, as previously mentioned. Shares tumbled in Q1 due to CEO Elon Musk’s involvement with the Department of Government Efficiency (DOGE), which pulled his attention away from his companies and left a major overhang on their valuations.

However, things started to rebound halfway through the year, and as the government started to phase out the $7,500 tax credit, demand spiked as consumers tried to take advantage of it.

Q3 deliveries were the highest in company history, and Tesla responded to the loss of the tax credit with the launch of the Model 3 and Model Y Standard.

Additionally, analysts have announced high expectations this week for the company on Wall Street as Robotaxi continues to be the focus. With autonomy within Tesla’s sights, things are moving in the direction of Robotaxi being a major catalyst for growth on the Street in the coming year.
