ZeRO-Infinity and DeepSpeed: Unlocking unprecedented model scale for deep learning training

Posted by in categories: robotics/AI, supercomputing, transportation

Since the DeepSpeed optimization library was introduced last year, it has rolled out numerous novel optimizations for training large AI models—improving scale, speed, cost, and usability. As large models have quickly evolved over the last year, so too has DeepSpeed. Whether enabling researchers to create the 17-billion-parameter Microsoft Turing Natural Language Generation (Turing-NLG) with state-of-the-art accuracy, achieving the fastest BERT training record, or supporting 10x larger model training using a single GPU, DeepSpeed continues to tackle challenges in AI at Scale with the latest advancements for large-scale model training. Now, the novel memory optimization technology ZeRO (Zero Redundancy Optimizer), included in DeepSpeed, is undergoing a further transformation of its own. The improved ZeRO-Infinity offers the system capability to go beyond the GPU memory wall and train models with tens of trillions of parameters, an order of magnitude bigger than state-of-the-art systems can support. It also offers a promising path toward training 100-trillion-parameter models.

ZeRO-Infinity at a glance: ZeRO-Infinity is a novel deep learning (DL) training technology for scaling model training, from a single GPU to massive supercomputers with thousands of GPUs. It powers unprecedented model sizes by leveraging the full memory capacity of a system, concurrently exploiting all heterogeneous memory (GPU, CPU, and Non-Volatile Memory express or NVMe for short). Learn more in our paper, “ZeRO-Infinity: Breaking the GPU Memory Wall for Extreme Scale Deep Learning.” The highlights of ZeRO-Infinity include:

A California Startup Now Offers a Full EV Battery in Just 10 Minutes

Posted by in categories: robotics/AI, sustainability, transportation

(Bloomberg) — On a Wednesday afternoon in May, an Uber driver in San Francisco was about to run out of charge on his Nissan Leaf. Normally this would mean finding a place to plug in and wait for a half hour, at least. But this Leaf was different.

Instead of plugging in, the driver pulled into a swapping station near Mission Bay, where a set of robot arms lifted the car off of the ground, unloaded the depleted batteries and replaced them with a fully charged set. Twelve minutes later the Leaf pulled away with 32 kilowatt hours of energy, enough to drive about 130 miles, for a cost of $13.

A swap like this is a rare event in the U.S. The Leaf’s replaceable battery is made by Ample, one of the only companies offering a service that’s more popular in markets in Asia. In March, Ample announced that it had deployed five stations around the Bay Area. Nearly 100 Uber drivers are using them, the company says, making an average of 1.3 swaps per day. Ample’s operation is tiny compared to the 100000 public EV chargers in the U.S.—not to mention the 150000 gas stations running more than a million nozzles. Yet Ample’s founders Khaled Hassounah and John de Souza are convinced that it’s only a matter of time before the U.S. discovers that swapping is a necessary part of the transition to electric vehicles.

Battery breakthrough makes flying cars commercially viable

Posted by in categories: innovation, transportation

‘I would expect these vehicles to make 15 trips, twice a day during rush hour to justify the cost of the vehicles,’ says researcher.


The key is to rapidly heat the battery to a certain temperature using a nickel foil, which then allows for ultra quick charging without causing any damage.

“I think flying cars have the potential to eliminate a lot of time and increase productivity and open the sky corridors to transportation,” Dr Wang said.

Waymo Self-Driving Trucks Will Soon Start Moving Freight Across Texas

Posted by in categories: robotics/AI, transportation

Last month, self-driving technology company TuSimple shipped a truckload of watermelons across the state of Texas ten hours faster than normal. They did this by using their automated driving system for over 900 miles of the journey. The test drive was considered a success, and marked the beginning of a partnership between TuSimple and produce distributor Guimarra. This is one of the first such partnerships announced, but TuSimple may soon have some competition from another big player in the driverless vehicles game: Alphabet Inc. subsidiary Waymo.

Yesterday, Waymo announced a partnership with transportation logistics company JB Hunt to move cargo in automated trucks in Texas. The first route they’ll drive is between Houston and Fort Worth, which Waymo claims is “one of the most highly utilized freight corridors in the country.”

At around 260 miles long, much of the route is a straight shot on Interstate 45. The trucks will have human safety drivers on board who will likely take over some of the city driving portions, but the goal is to use the automated system as much as possible. A software technician will be on board as well, which makes sense given software will be doing the bulk of the driving.

UK air taxi firm Vertical Aerospace to float on New York stock market

Posted by in categories: finance, transportation

The aircraft could be used to transfer passengers between home and airports, Virgin believes. It would be able, for example, to make the 56-mile journey from Cambridge to Heathrow in 22 minutes, compared with a 90-minute drive.

The announcement represents another step in the race to making mass electric flight and air taxis a reality. Some analysts have predicted the sector could be worth £150bn by 2040 but significant hurdles remain, including regulation and safety certification. The VA-X4 has yet to take its first test flight. Dómhnal Slattery, the chief executive of Avolon, said its order would “accelerate the inevitable commercial rollout of zero-emissions aircraft. Before the end of this decade, we expect zero-emission urban air mobility, enabled by eVTOLs, to play an increasingly important role in the global commercial aviation market.”

Nvidia acquires hi-def mapping startup DeepMap to bolster AV technology

Posted by in categories: mapping, robotics/AI, transportation

Chipmaker Nvidia is acquiring DeepMap, the high-definition mapping startup announced. The company said its mapping IP will help Nvidia’s autonomous vehicle technology sector, Nvidia Drive.

“The acquisition is an endorsement of DeepMap’s unique vision, technology and people,” said Ali Kani, vice president and general manager of Automotive at Nvidia, in a statement. “DeepMap is expected to extend our mapping products, help us scale worldwide map operations and expand our full self-driving expertise.”

One of the biggest challenges to achieving full autonomy in a passenger vehicle is achieving proper localization and updated mapping information that reflects current road conditions. By integrating DeepMap’s tech, Nvidia’s autonomous stack should have greater precision, giving the vehicle enhanced abilities to locate itself on the road.

Do you want to work for Tesla remotely and test its latest Autopilot and Full Self-Driving features? You may be in luck as we learn that the automaker is now looking to hire self-driving car test drivers around the world.

You don’t even need a college education.

When it comes to Autopilot and Full Self-Driving package features, people often say that Tesla’s own paying customers are the testers and that’s mostly true, but the automaker also does plenty of internal testing.

Segway (Yes, Segway) Is Making a Hybrid Motorcycle Worthy of All Your ‘Tron’ Fantasies

Posted by in categories: energy, transportation

The bike’s powertrain uses a fuel cell to turn gaseous hydrogen into electrical energy.


The engine setup holds its own, too. The Apex H2 will feature a hybrid powertrain that will convert gaseous hydrogen into electrical energy via a special fuel cell, reports New Atlas. Ninebot says the hydrogen-electric setup will be able to generate over 80 horsepower and rocket the bike from zero to 60 mph in less than four seconds. Considering that the original Segway—yes, the infamous two-wheel personal transporter favored by mall cops—topped out at 10 mph, that’s pretty impressive, even if it is slower than the Apex concept’s quoted top speed of 124 mph. Of course, there’s one key difference between the two bikes: The Apex H2 will be one of the rare concept vehicles you’ll be able to buy.
