respected sir ,
the program is recognized by all the nodes now.thanku very
much.this was when i tried to run test program in amber6/test as
make test.sander
Now I tried to test run a realcase promblem as
mpirun -np 4 sander_classic -O -i ...
But just after the program started it stops with following
message

   $ mpirun -np 4 sander_classic -O -i minim.in -o test.out -p
test.top -c test.coord -r tres
tart -ref test.coord
  All processors started
  All processors started

   Unit 5 Error on OPEN: minim.in
[0] MPI Abort by user Aborting program !

It seems that [at least] one of processes that was started with
mpirun
did not invoke MPI_INIT before quitting (it is possible that more
than
one process did not invoke MPI_INIT -- mpirun was only notified of
the
first one, which was on node n0).

mpirun can *only* be used with MPI programs (i.e., programs that
invoke MPI_INIT and MPI_FINALIZE). You can use the "lamexec"
program
to run non-MPI programs over the lambooted nodes.
