Package Information

Description:

rocSHMEM is a GPU-centric communication runtime following the OpenSHMEM partitioned global address space model. Its distinguishing feature is that device code initiates its own transfers: puts, gets and collectives are called from inside a kernel rather than being marshalled by the host between kernel launches, which suits fine-grained communication that would otherwise force a launch boundary. It can run over an MPI bootstrap for multi-process work, or within a single node over HIP IPC.
