All, This isn't specifically an Open MPI issue, but as that is the MPI stack I use on my laptop, I'm hoping someone here might have a possible solution. (I am pretty sure something like MPICH would trigger this as well.)
Namely, my employer recently did something somewhere so that now *any* MPI application I run will throw popups like this one: https://user-images.githubusercontent.com/4114656/30962814-866f3010-a44b-11e7-9de3-9f2a3b0229c0.png though for me it's asking about "orterun" and "helloworld.mpi3.exe", etc. I essentially get one-per-process. If I had sudo access, I suppose I could just keep clicking "Allow" for every program, but I don't and I compile lots of programs with different names. So, I was hoping maybe an Open MPI guru out there knew of an MCA thing I could use to avoid them? This is all isolated on-my-laptop MPI I'm doing, so at most an "mpirun --oversubscribe -np 12" or something. It'll never go over my network to anything, etc. -- Matt Thompson “The fact is, this is about us identifying what we do best and finding more ways of doing less of it better” -- Director of Better Anna Rampton
