That's rather an ImplicitGlobalGrid related thing. Depending on your server install you can simply launch diffusion3D_multigpucpu_novis.jl
using e.g.
mpirun -n 8 julia --project ./diffusion3D_multigpucpu_novis.jl
Check before hand your MPI install is working and you may enable GPU-aware MPI upon setting IGG_CUDAAWARE_MPI=1
.
Thank you very much !
I read the README.md
in both ParallelStencil.jl
and ImplicitGlobalGrid.jl
and I could not find the command you proposed.
It could be interesting to add a section on how to launch the examples (you type this, you should obtain this).
A quick note in case someone fall on the same problem. If your local MPI
installation does not match the MPI.jl
's one then the command mpirun -n 8 julia --project ./diffusion3D_multigpucpu_novis.jl
launches 8 times the same monoprocess execution with a warning. Fixing the MPI mismatch fix the pb.
how do you to launch an example (e.g. diffusion3D_multigpucpu_novis.jl) on multiple processes ?
