GPUDirect RDMA

Harnessing the massive computational power of modern-day Graphics Processing Units (GPUs) allows building extremely powerful clusters and super-computers. NVIDIA’s GPUDirect technology enables direct access to a GPU over the PCI bus eliminating unnecessary memory copies, dramatically lowering CPU overhead, and reducing latency.

With GPUDirect RDMA using Chelsio’s iWARP RDMA adapters, network access to the GPU is achieved at 10 and 40Gb speeds across a standard Ethernet network infrastructure with both high performance and high efficiency.
