iohann.s.titov@gmail.com Ivan S. Titov 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. Enable the HIP IPC conduit for communication between GPUs on one node Enable the SDMA transport conduit, which upstream documents as MI300X and newer; harmless but not useful on other parts Use an external MPI implementation for host-side bootstrap and launching Restrict the build to single-node support only ROCm/rocm-systems
