We are talking about whether we can use MPICH-G2 to pass messages to nodes of different clusters.

The above link is related to that.

Useful link to build fortran compilers with MPICH-G2

http://www.cvc.mun.ca/software/mpich-g2/mpichman-globus2/node36.htm

We found that F90 compilers were missing in our fortran 90. Wen we tried to rebuild with the --enable-f90 option it said that the f90 compilers were missing (although they were included in the path variable).

This link provides the solution on how to add the F90 compilers to the env.

I ran sample Fortran MPI programs (Fortran77) on medusa and proc1 using MPICH-G2. The programs are simple hello world and matrix programs.
They were compiled using MPICH-G2s mpif77 compiler. We apparently dont have an mpif90 compiler. Could some one comment on how to get Fortran90 code running.

I am having problems in creating an RSL for running MPICH-G2 programs on the condor pool.

This is a link from globus mailing list that describes a similar problem with PBS and its solution.

It might be something to look at:

We are able to run the program provided by Nova Ahmed of GSU on 3 differenet machines
proc1, nori, and thing2 using MPICH-G2.

Once medusa is up we will try check to see why MPICH-G2 is not running on it.

It looks like if one wants to run the mpi program on more than one machine, the only way to do is to create a RSL.

The reason is it looks for the LD_LIBRARY_PATH.

If this path is different for the other machines from the machine it is running on it is not able to find it.

Do not know why it cannot get from $GLOBUS_LOCATION and LD_LIBRARY_PATH already set on the machines.

We were able to get the MPICH-G2 test program running from proc1 on 3 different machines - thing2, nori, and proc1.

On Medusa it is not running because of a missing library libglobus_duroc_bootstrap_gcc32.so.0

We are going to install globus 3.2 and check with it.
