Benchmarking Gpudirect Rdma On Modern Server Platforms Nvidia E. nvidia gpudirect rdma is a technology which enables a direct path for data exchange between the gpu and third party peer devices using standard features of pci express. examples of third party devices include network interfaces, video acquisition devices, storage adapters, and medical equipment. enabled on tesla and quadro class gpus. The whole point of this blog post is that the measured rdma bandwidth actually depends on your particular platform. in your case, you could check: cpu model (lscpu), the pcie topology (nvidia smi topo m), the system pcie max payload size (sbios), the infiniband hca maxpayload and maxreadreq, etc.
Benchmarking Gpudirect Rdma On Modern Server Platforms Nvidia Please note that mv2 cpu mapping=<core number> has to be a core number from the same socket that shares the same pci slot with the gpu. the mv2 gpudirect limit is used to tune the hybrid design that uses pipelining and gpu direct rdma for maximum performance while overcoming p2p bandwidth bottlenecks seen on modern systems. Benchmarking gpudirect rdma on modern server platforms nvidia gpudirect rdma is a technology which enables a direct path for data exchange between the gpu and third party peer devices using standard features of pci. Step 2 – exchange info: using an out of band (oob) mechanism (for example, linux sockets) peers exchange info about rdma queue (s) and memory buffers to be accessed remotely. step 3 – data path: the two peers execute an rdma read write send recv to exchange data using remote memory addresses. Gpudirect rdma is a technology introduced in kepler class gpus and cuda 5.0 that enables a direct path for data exchange between the gpu and a third party peer device using standard features of pci express. examples of third party devices are: network interfaces, video acquisition devices, storage adapters. gpudirect rdma is available on both.

Gpudirect rdma is a technology in nvidia gpus that enables direct data exchange between gpus and a third party peer device using pci express. the third party devices could be network interfaces such as nvidia connectx smartnics or bluefield dpus, or video acquisition adapters. gpudirect storage (gds) enables a direct data path between local or. Designed specifically for the needs of gpu acceleration, gpudirect rdma provides a direct communication path between nvidia gpus in remote systems using infiniband. this eliminates the system cpus and the required buffer copies of data via the system memory, resulting in superior performance. figure 1: block diagram of nvidia gpudirect rdma.
