Is it in principle possible to add support for the NVSHMEM API, e.g. calls to nvshmem_my_pe(), etc., to the NVPTX backend? Or is this stuff outside the realm of simply lowering instructions to PTX - maybe because NVCC is doing some other magic alongside? If it's simply not possible due to how NVIDIA implemented NVSHMEM then it would be good to know. Thanks, Frank -------------- next part -------------- An HTML attachment was scrubbed...
