Hello all, I have an MPI CFD code that uses some OpenCL kernels to speed up meshing (signed distance functions). I am trying to run it on an M1 MacBook Pro, but I’m having a weird issue where the OpenCL kernels will fail returning data from the buffers to the MPI processes if run simultaneously. F…

FYI I solved this issue by avoiding to have many MPI CPUs simultaneously running command queues on the same GPU.
