Hello,
I have tried to run the executable "wrf.exe", using
mpirun -machinefile /tmp/108388.1.par2/machines -np 4 wrf.exe
but, I've got the following error:
--
mpirun noticed that process rank 1 with PID 9942 on node
pa
Sure, this is possible and generally works, although it is not defined
by the MPI standard. Regular shared memory rules apply: you may have to
add additional memory consistency and/or synchronization calls depending
on your platform to ensure that MPI sees intended data updates.
Best,

If the mmap() pages are created with MAP_SHARED, then they should be
sharable with other processes in the same node, isn't it? MPI
processes are just like any other process, aren't they? Will one of
the MPI Gurus please comment?
Regards
Durga

More in detail,
is it possible use mmap() function from MPI process and sharing these memory
between others processes?
