[mpich-discuss] mpich2 Parallel job real time.

[mohamed makhyoun]

Dear users and developers:

Recently I compiled successfully a parallel binary (cfour software from www.cfour.de)

using pgf90 version 9.0 /mpich2 . The main program is a driver that initiate the parallel job internally 

without the common command: mpiexec -np  4 cfourbinary (for four nodes ).

The steps taking in running the program is as follows under linux:

mpd &

cfourbinary input > output

The problem is that  the
 real time for running the parallel job is nearly the same as the serial job.  Is something missing ? Also the ps command during the run indicates no communication either with ssh or rsh.

Best Regard

Mohamed Makhyoun
