Gpu memory access latency
WebGDRCopy is a low-latency GPU memory copy library based on GPUDirect RDMA technology that allows the CPU to directly map and access GPU memory. GDRCopy also provides optimized copy APIs and is widely used in high-performance communication runtimes like UCX, OpenMPI, MVAPICH, and NVSHMEM. cudaMemcpy uses the GPU … WebImproves bandwidth but also adds latency. GPU Memory System GPU Memory accesses measured at VE: Sustained fabric bandwidth ~90% of peak GPU cache hit ~150 cycles, cache miss ~300 cycles. TLB miss adds 50-150 cycles GPU cache line read after write to same cache line adds ~30 cycles
