The GPU supports double precision (FP64), single precision (FP32) and half precision (FP16) compute tasks, unified virtual memory and page migration engine. NVIDIA Tesla V100 GPU adapter is a dual-slot 10.5 inch PCIe 3.0 card with a single NVIDIA Volta GV100 graphics processing unit (GPU). The V100S GPU offers improved performance over the V100, featuring a ~25% increase in memory bandwidth and higher FLOPS. NVIDIA Tesla V100S GPU adapter is a dual-slot 10.5 inch PCIe 3.0 card with a single NVIDIA Volta GV100 graphics processing unit (GPU). A100’s third-generation Tensor Core technology now accelerates more levels of precision for diverse workloads, speeding time to insight as well as time to market. As the engine of the NVIDIA data center platform, A100 can efficiently scale up to thousands of GPUs or, using new Multi-Instance GPU (MIG) technology, can be partitioned into seven isolated GPU instances to accelerate workloads of all sizes. If you're wondering what anyone would do with all of those GPUs, they're looking at things like artificial intelligence, weather systems, and other supercomputing tasks.The NVIDIA A100 Tensor Core GPU delivers acceleration at every scale for AI, data analytics, and HPC to tackle the world’s toughest computing challenges.

Perhaps more importantly for the Tesla P100, peak power use should be significantly lower than K80, meaning a full rack of twelve DGX-1 servers should only need around 30-40kW.

Using the existing K80, GPUltima is slightly faster on FP32 per rack, but slower on FP64. Of course, that's FP16 TFLOPS, so if you need FP32 precision you're looking at 1017 TFLOPS, or 509 TFLOPS for FP64. Nvidia's upcoming DGX-1 server with eight Telsa P100 Pascal GPUs can provide up to 170 TFLOPS of performance in a 3U chassis, and with 12 of those in a rack, 2035 TFLOPS per rack. Each 3U rack comes equipped with three 3000W 240V PSUs (one for redundancy), so a data center needs to be able to supply over 50kW per rack, with 76kW being "safe." The good news is it can also roast marshmallows and hot dogs if you're hungry. Just how much power does the GPUltima require? We were told that the typical power use under load for the system sits at around 5000W, though peak power use can jump a bit higher. There's a problem with stuffing that many GPUs into a rack, of course: you still need to provide power and cooling. Or if you want FP64, you'd drop down to 373 TFLOPS. Each has 8.74 FP32 TFLOPS, for a combined 1,120 TFLOPS per rack. Let's stick with the 128 Tesla K80 GPUs, though. And when you can count on cards being around that long, you can do crazy stuff like this:

Companies are often faced with needing to balance buying faster consumer hardware that will be phased out sooner, or paying the higher price for professional cards that are clocked slower but will be around for five or more years. Quadro and Tesla are kept in production for much longer, as part of the professional market they cater to. One of the problems vendors face when using consumer GPUs is that the cards have a relatively short shelf life in another year, there won't be many GTX Titan X cards around for purchase, assuming a Pascal variant takes its place. On a related note, we saw a lot of consumer GM200 cards in workstations, which isn't too surprising since there was no high-performance FP64 Quadro card for Maxwell.

What's interesting is that the EVGA cards are open air coolers rather than blowers when asked about this, Velocity Micro said that it was "mainly for show" and that normally they would use reference blowers to help with cooling. Here, the case is packed with eight GTX 980 Ti cards from EVGA, paired with dual Xeon processors (these were older E5-2660 v3 right now, though newer Xeon v4 models are supported). Systems like this were all over the show floor, but the Velocity Micro system caught our eye as it was one of the few to actually use GTX 980 Ti-most were doing GTX Titan X if they used consumer GPUs, while Quadro and Tesla were in the majority of professional servers and workstations.
