I don't think you should copy the executable files to other machines.

Instead, you check the file machines.LINUX in the

/home/gimul/1Work/mpich/util/machines

then machines.LINUX file could be ;

machine1
machine2
machine3
machine4

It will work  mpirun -np 4 fpi something like ;

pi = 0.044422   and so forth
