chelsioToday Chelsio Communications announced that its T5 iWARP RDMA over Ethernet adapters now fully support NVIDIA GPUDirect RDMA technology.

NVIDIA GPUDirect RDMA is a key component of the NVIDIA Tesla Accelerated Computing Platform, the leading platform for accelerating data analytics, deep learning and scientific computing. GPUDirect RDMA eliminates CPU bandwidth and latency bottlenecks using direct data transfers between GPUs and other PCIe devices, bypassing the host processor and memory. With its full support for NVIDIA GPUDirect and NVIDIA GPU Tesla accelerators, Chelsio is delivering a high-performance Ethernet connectivity solution to address customers’ most demanding data analytics and scientific applications.

We are pleased to support the leading accelerated computing platform with iWARP, and help NVIDIA bring new levels of computational performance to data analytics and HPC customers,” said Wael Noureddine, vice president of technology, Chelsio. “Our iWARP RDMA solution is recognized as an easy to use, industry-leading connectivity fabric for RDMA using standard Ethernet. We look forward to increased adoption of Ethernet in high performance applications.”

Recently published benchmarks illustrate the benefits of NVIDIA GPUDirect RDMA using Chelsio’s T5 adapters running at 40Gbps. The benchmarks show a 4X latency reduction across the message size range and a 5X bandwidth improvement for large messages with Chelsio T5 40GbE iWARP, compared to standard 40G server NICs. The results demonstrate the superior throughput of Chelsio’s 40G iWARP RDMA compared to alternative RDMA over Ethernet protocols (see benchmark report).

With the addition of 40Gb Ethernet and other advanced technologies to the Tesla Accelerated Computing Platform, NVIDIA continually provides an expanded range of flexible, ultra-high performance computing solutions for HPC and enterprise customers,” said Duncan Poole, director of Platform Alliances at NVIDIA. “Enabling direct data transfers between Chelsio devices and NVIDIA GPUs, iWARP with GPUDirect RDMA improves performance by maximizing bandwidth while minimizing latency.”

The production-level T5 iWARP driver software for NVIDIA Tesla GPU accelerators is available immediately.
