>>Hi,
>>thanks very much! I set variable value MPI_GLOBMEMSIZE=536870912 forever :-)
>>Now FF works up to 32 cores. I found the following text:
>>"By default, mpich limits the number of processes for the ch_shmem device to 32, unless it determines at configure time that the machine has more processors.
>>You can override this limit by setting the environment variable PROCESSOR_COUNT to the maximum number of processes that you will want to run, and then reconfigure and remake mpich."
>>Does it concern the given restriction? If yes, what to do? I am far from such things.
