It seems to be related to the size of the array, using 1000x1000 I get results similar to yours, but just using a bigger array I get: ``` @time map(half_julia,...

Yes, the results were the fastest out of 3 consecutive calls. I just tried on my machine at work, which is almost the same except for the CPU and linux...

Maybe we should just ship openmpi binaries using BinaryBuilder, that way it will work out of the box for everyone. I'm not sure how well this would cross-compile for Windows,...

Yes, of course it would not cover all use cases, but it would make it easier for other packages to depend on MPI.jl and "just work" within the confines of...

Yes, it's debatable what should be the default. Maybe we could also detect if an MPI is already installed and loaded? I also think a cluster user would be more...

Yes, the version compatibility is a must-have, I had planned to look at it too, but I haven't even gotten round to looking at @JaredCrean2 's work.

I don't know if the test failures here are my doing...
