Can more than 3 users in a cluster do 'mpirun' concurrently with 2-user floating license?
I wonder if the Intel license is applicable when compiling or when run-time.
I believe the seat limits for MPI license don't apply at run time. The license tokens should return to the available pool shortly after compilation, regardless of how much time you spend running.
