HIP Transfer Streams (HIts)

This application is designed to launch intra-node transfer streams in an adjustable way. It may trigger different types of transfers concurrently. Each transfer is bound to a stream. Transfer buffers in main memory are allocated (by default) on the proper NUMA node.

Dependencies

• Rocm
• libnuma

How to build HIts

% make

How to run HIts

% ./hits [ARGS...]

Arguments are :

-d, --dtoh=<id>            Provide GPU id for Device to Host transfer.
-h, --htod=<id>            Provide GPU id for Host to Device transfer.
-i, --iter=<nb>            Specify the amount of iterations. [default: 100]
-m, --disable-pinned-memory   Use pageable allocations instead.
-n, --disable-numa-affinity   Do not make the transfer buffers NUMA aware.
-p, --dtod=<id,id>         Provide comma-separated GPU ids to specify which
                           pair of GPUs to use for peer to peer transfer.
                           First id is the destination, second id is the
                           source.
-s, --size=<bytes>         Specify the transfer size in bytes. [default:
                           1073741824]
-?, --help                 Give this help list
    --usage                Give a short usage message
-V, --version              Print program version
