I’ve been recently playing with the MPI wrappers for Julia (MPI.jl) – yesterday I built a dumb test problem in both C and Julia and was comparing performance, and Julia is pretty close to C which is impressive! 
I thought I might be able to close the gap even further by using the PackageCompiler.jl package to speed up the initial loading cost in Julia, but I can’t get it to play nicely. If I run:
julia --sysimage myImage.so --project myProject.jl
it works fine, but if I run:
mpiexec -n np julia --sysimage myImage.so --project myProject.jl
I get a signal 6 abort. This is my first experience with both the MPI.jl and PackageCompiler.jl packages, so any tips/insights are much appreciated!
