hej,
i know its not really the wright spot for this question, its more like general software relatet but anyway i hope someone can answer me this:

when i give multiple mpiruns to my cluster, in multiple terminals (since one mpirun blocks one terminal) they apear not to be aware of each other. even when marked with -nooversubscribe it sometimes happens. i can trick it into giving the right amount of jobs to the specific machines with extra hostfiles for every run and specific options, but that's exausting and i think this slows the performance down.

so, how do i make them aware of each other? or am i wrong on this..?

thanks!!
