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. WebCUDA performance measurement is most commonly done from host code, and can be implemented using either CPU timers or CUDA-specific timers. Before we jump into these performance measurement techniques, we need to discuss how to synchronize execution between the host and device.
