WebRemote direct memory access (RDMA) enables peripheral PCIe devices direct access to GPU memory. Designed specifically for the needs of GPU acceleration, GPUDirect RDMA provides direct communication between … Latency test results on various GCN implementations. Since its debut about a decade ago, AMD has steadily augmented GCN with more cache and higher clockspeeds. Memory latency has come down partially because getting to L2 was faster, but latency between L2 and VRAM has been decreasing as well. See more GPUs have headline grabbing compute and memory bandwidth specs, but need tons of parallelism to utilize that. Unlike CPUs that do out of … See more The first version of the latency test used a fixed stride access pattern. After testing across several GPUs, none of them did any prefetching, so any jump greater than the burst read size … See more Turing and Ampere show similar patterns here, but curiously Turing’s GDDR6 has higher latency than Ampere’s GDDR6X. On Pascal, GDDR5X … See more With the newer test, RDNA 2 and Ampere have similar latency to their fastest cache, but Ampere’s L1 is larger than RDNA 2’s L0. Nvidia can also change their L1 and shared memory allocation to provide an even larger L1 size … See more
