Dear lam-mpi users and developers,
I have some problems when running a program with mpirun and reading
standard input from a file. If I compile the following silly fortran
code
program read_variable
implicit double precision (a-h,o-z)
include 'mpif.h'
call MPI_init(ie)
call MPI_comm_rank(MPI_COMM_WORLD,myid,ie)
if (myid.eq.0) read*,a
call MPI_finalize(ie)
stop
end
with the command mpif77 "mpif77 sillycode.f -o sillycode" and I give the
commands
echo 1 > inputfile
mpirun -np 2 ./sillycode < inputfile
the program still waits reading from the terminal. If I understand
correctly in the mpirun man page, such a redirection can be done.
I booted lam-mpi with the command "lamboot -v lamhosts", where the file
lamhosts contains this line "mycomputer cpu=2".
My laminfo gives the following output
