BusSpeedDownload and BusSpeedReadback

Description Measures the bandwidth of the PCIe bus connecting the host and device by repeatedly transferring chunks of data ranging in size from 1KB to 64MB.

Options

• --nopinned - Disable the use of pinned (a.k.a. page-locked) host memory)

Problem Sizes: Always 1 KB to 64 MB. (Note: L0 benchmarks do not use -s size classes)

Precision: N/A

Includes PCIe Transfer Time: Obviously

Specific Tests

• DownloadSpeed - Bandwidth of the host->device transfer in GB/s (separate results printed for each transfer size)
