[MITgcm-support] errors for MPI simulation

[Clark Yxh]

Hi,

*I'm trying to change my non-MPI simulation to parallel simulations to
increase the speed, but the following error showed up:*

Open RTE was unable to open the hostfile:
    mf
Check to make sure the path and filename are correct.

A daemon (pid unknown) died unexpectedly on signal 1  while attempting to
launch so we are aborting.

There may be more information reported by the environment (see above).

This may be because the daemon was unable to find all the needed shared
libraries on the remote node. You may set your LD_LIBRARY_PATH to have the
location of the shared libraries on the remote nodes and this will
automatically be forwarded to the remote nodes.

mpirun noticed that the job aborted, but has no info as to the process
that caused that situation.

mpirun: clean termination accomplished

*Following is my configuration for SIZE.h and SIZE.h_mpi*
     &           sNx =  10,
     &           sNy =  140,
     &           OLx =   2,
     &           OLy =   2,
     &           nSx =   5,
     &           nSy =   1,
     &           nPx =   4,
     &           nPy =   1,
     &           Nx  = sNx*nSx*nPx,
     &           Ny  = sNy*nSy*nPy,
     &           Nr  =  10)

*Following is the command I entered:*
cd ~/mitgcm/pgmpi/pgmpi_v1
mkdir pgmpi_v1a
cd pgmpi_v1a
../../../tools/genmake2 -mods=../code -mpi -of
=../../../tools/build_options/linux_amd64_gfortran
make depend
make -j 4
mpirun -np 4 -machinefile mf ./mitgcmuv



*Any help appreciated, thank you!*

*Sincerely,*
*Clark*
