Problem A basic test of CUDA-aware MPI with MPI.jl fails on both our Cray supercomputer and on another cluster: 1) On Cray system 1.1) Test and error: omlins@dom101:~> export MPICH_RDMA_ENABLED_CUDA=1 omlins@nid00002:~> julia julia> using MPI julia> using CuArrays julia> MPI.Init() julia> …

I just ran over this old topic and will quickly update it: meanwhile, CUDA-aware MPI works on the Cray system by just setting: export MPICH_RDMA_ENABLED_CUDA=1 export JULIA_CUDA_USE_BINARYBUILDER=false I guess the problem was simply that CUDA.jl did not use the system installation in the past as i…
