Introducing at SC15: GPUltima 
At SC15, we've introduced the OSS GPUltima petaflop compute platform in a single rack. This high-density platform delivers petaflop performance at greatly reduced cost and space requirements. The OSS GPUltima supports up to 128 double-wide interconnected accelerators. Consuming only 56 kilowatts of power, the platform uses 94 percent less power than other petaflop solutions. This reflects a tremendous cost savings in power and cooling. In addition the single-rack occupies 96 percent less space than other solutions. The OSS GPUltima employs 64 OSS PCIe Gen3 x16 adapters and cables between the OSS servers and the OSS High Density Compute Accelerators (HDCA), each containing 16 high-performance NVIDIA® Tesla® K80 GPU accelerators and 32 Mellanox EDR 100Gbs InfiniBand adapters and cables connecting the GPUs through a 36-port InfiniBand switch. One Stop Systems' PCIe expansion systems provide high speed connectivity between the CPU and IO cards. While IO cards have traditionally occupied slots in the server cabinet, OSS designs expansion appliances that support large numbers of high speed cards with latest technology PCIe Gen3 slots, efficient cooling, and sufficient power. 
 
NVIDIA Tesla K80 GPU accelerators are the flagship offering of the Tesla Accelerated Computing Platform, the leading platform for accelerating data analytics, deep learning and scientific computing. It integrates the world’s fastest GPU accelerators, development tools, high-speed communication technology, a supported ecosystem and the NVIDIA CUDA® parallel computing model. NVIDIA's GPUDirect technology enables multiple GPUs to directly read and write CUDA host and device memory, eliminating unnecessary memory copies, dramatically lowering CPU overhead, and reducing latency, resulting in significant improvements in application performance.
 
Mellanox EDR 100Gb/s InfiniBand adapters, switches, cables and software are the most efficient solutions for server and storage connectivity, delivering high throughput, low latency and industry-leading application performance for enterprise solutions that are widely deployed across HPC, Cloud, Web 2.0, and Big Data satisfying the most demanding data centers requirements. The OSS GPUltima employs 32 EDR 100Gb/s InfiniBand adapters and a 36-port EDR 100Gb/s InfiniBand switch from Mellanox in each platform.
HPC Application Highlight: Medical
GPUs and flash memory are used in numerous medical applications today and the number is rapidly growing. The need to store and transcribe huge amounts of data through image and data processing is becoming overwhelming. The more GPUs and flash memory available, the quicker the data can be used. GPU appliances supporting multiple NVIDIA GPUs and Intel Phi coprocessors and Flash memory appliances supporting multiple Fusion-io flash memory cards are quickly becoming the best and most economical way of accomplishing this tremendous feat.
