Hello, thanks for your help and suggestions.
At the end it was no issue with OpenMPI or with any other system stuff, but rather a single line in our code. I thought I was doing the tests with the -fbounds-check option, but it turns out I was not, arrrghh!! At some point I was writing outside one of our arrays, and you can imagine the rest... That it was happening only when I was running with '--bind-to none' and only in my workstation brought me down all the wrong debugging paths. Once I realized -fbounds-check was not being used, figuring out the issue was a matter of seconds... Our code is now happily performing the +3000 tests without a hitch.
