Gpu memory access latency
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 WebArrays allocated in device memory are aligned to 256-byte memory segments by the CUDA driver. The device can access global memory via 32-, 64-, or 128-byte transactions that are aligned to their size. For the C870 or any other device with a compute capability of 1.0, any misaligned access by a half warp of threads (or aligned access where the ...
