MPI execution failed

[Adjeiinfo]

I am new to fortran.

[xxx]$ gfortran --version
GNU Fortran (GCC) 4.4.6 20110731 (Red Hat 4.4.6-3)
Copyright (C) 2010 Free Software Foundation, Inc.

Then I could build my project using gfortran

I run the following to command to run the code
mpirun -f myhostfile -3 5 /myhome/myproject/mympiexe.x [/quote][/topic]

I got the following error

[mpiexec@c24] set_default_values (./ui/mpich/utils.c:1292): no executable specified
[mpiexec@c24] HYD_uii_mpx_get_parameters (./ui/mpich/utils.c:1510): setting default values failed

Could anyone help me solve this issues?

What is "mpirun -3 5 ..." supposed to do? Do you want 5 processes?

Thankyou for your reply. I was out of office.

Following is the my job setting bash file

#! /bin/bash
#$ -S /bin/bash
#nodes=5
#ncpu=`expr $nodes \* 2`
#$ -q node.q
#$ -pe core8 40
#$ -j y
#$ -N mpitst
cat $TMPDIR/machines | sed -e 's/$/:2/' > myexecfile
mpirun -f myexecfile -np $ncpu /myhome/myproject/mympiexe.x <<EOF

Ah, GridEngine?

If you build your MPI with GE integration you can just say "mpirun <yourprogram>" at the end and the MPI will take care of all the hostfile and -np bits for you.

Code: Select all

#nodes=5
#ncpu=`expr $nodes \* 2` 

these are just comments as far as the shell executing the job is concerned and are ignored.

Not sure what the "here" (<<) on the last line is supposed to do? Are there more lines you truncated?

tony-curtis,

Thank you. It works now. My bad.

Thanks again.

I am happy to find your information here. Before I submit my job, I have to modify
the cpu/cores required for my computing cluster (#$ -q node.q #$ -pe core8 40).
But, I do not know what should I write after "#$ -q" and "#$ -pe". How to know it?
I would be very grateful if you could answer me as much detail as possible. (i'm a rookie)
