Cirrascale GX8 Series Rackmount Server Overview
The new Cirrascale GX8 Rackmount Series supports the Intel® Xeon® processor E5-2600 v3 product families and up to 10 PCIe Gen 3.0 x16 compatible devices enabling multidevice peering on a single PCIe root complex, such as the NVIDIA® Tesla® M40 GPU cards. This multi-device peering on a single PCIe root complex makes it a perfect solution for GPU accelerated applications and libraries like those used for deep learning, data analytics and molecular dynamics such as Torch 7, Theano, Caffe, and TensorFlow.
The GX8 Series rackmount servers are different from other GPU supporting hardware implementations. Most of the hardware configurations available today only provide maximum performance between specific pairs of GPUs; and since GPUs are paired up, jobs requiring communication between arbitrary GPUs experience a performance impact. Additionally, there can be a significant performance impacts with trying to scale more than four GPUs on multi-socket systems. These have been persistent problems for customers who are pushing the limits of GPUs with large, complex data-sets and calculations, or where data must be streamed between GPUs. Cirrascale has been able to overcome these issues, and achieve near linear performance scaling with its design.
By utilizing the Cirrascale SR3615 PCIe 96-lane switch riser, the Cirrascale GX8 supports up to eight NVIDIA Tesla M40 GPU cards and provides room for additional InfiniBand® or NVMe storage devices while enabling increased bandwidth and lower latencies between PCIe Gen3 devices than are possible in traditional systems. By enabling up to 8 discrete GPU accelerators to communicate directly with each other on the PCI bus, free of the need for host CPU intervention, they can create a "micro-cluster", sharing a single memory address space.
Maximize PCIe Bandwidth
Cirrascale is a strong believer in utilizing a technology to its fullest potential whenever possible and GPUs and GPU Accelerators are no exception. If the GPU has a PCIe Gen3 x16 link, then it should use it when communicating with other GPUs — any other GPUs. Our switch riser technology allows us to scale and peer multiple PCIe x16 Gen3 cards on a single root hub ensuring that the maximum PCIe bandwidth is available utilized for inter-card communication.
Minimize Intercard Latency and Obtain Consistent Performance Between GPUs
Our switch riser allows GPUs to communicate as if they are all on the same bus... because they are. Gone are the days of needing a bounce-buffer in host memory, or leaving GPU DMA engines unused because they couldn't address other devices in the system. This reduces intercard latency while helping to maintain a consistent performance level between GPUs.
Enable GPU-Centric Development and Usage
Since most all of the GPU traffic is passed between the GPUs directly via the Cirrascale SR3615 switch riser, a very negligible amount of host resources are needed to perform GPU work. Additionally, with a single address space and simultaneous inter-card communication at full PCIe x16 Gen3 speeds, software can spend more time doing work than thinking about when to schedule data copies.
