Cuda memory bandwidth test

WebApr 2, 2024 · we can estimate L2 bandwidth as: 2*64*2MB/123us = 2.08TB/s Both of these are rough measurements (I'm not doing careful benchmarking here), but bandwidthTest on this V100 GPU reports a device memory bandwidth of ~700GB/s, so I believe the 600GB/s number is "in the ballpark". WebOct 25, 2011 · You do ~32GB of global memory accesses where the bandwidth will be given by the current threads running (reading) in the SMs and the size of the data read. All accesses in global memory are cached in L1 and L2 unless you specify un-cached data to the compiler. I think so. Achieved bandwidth is related to global memory.

WebApr 24, 2014 · To my understanding: Bandwidth bound kernels approach the physical limits of the device in terms of access to global memory. E.g. an application uses 170GB/s out of 177GB/s on an M2090 device. A latency bound kernel is one whose predominant stall reason is due to memory fetches. WebWhen building the OSU benchmarks, you must verify that the proper flags are set to enable the CUDA part of the tests. Otherwise, the tests will only run using the host memory instead. which is the default setting. Additionally, make sure that the MPI libraries, OpenMPI, are installed prior to compiling the benchmarks.
