Paul, I'm sure this isn't the response you want to hear, but I'll suggest it anyway: Queuing systems can forward the submitters environment if desired. For example, in SGE, the -V switch forwards all the environment variables to the job's environment, so if there's one you can use to launch your

Re: [OMPI users] Anyone with Visual Studio + MPI Experience

Miguel, Thanks for the assistance. I don't have the MPI options you spoke of, so I figured that might have been part of the HPC Pack. I found a couple of web pages that helped me make progress. I'm not 100% there, but I'm much closer, say 85% of the way there. Now I can get an Fortran+MPI

Miguel, I'm using VS 2010 Professional + Intel Visual Fortran. I don't have the "Debugger to Launch" option in my version (or I'm looking in the wrong place), and don't see MPI options any where. Do you have any additional software installed, like the HPC Pack 2008? Prentice On 07/04/2011 04:32

One of the researchers I support is writing some Fortran code that uses Open MPI. The code is being compiled with the Intel Fortran compiler. This one line of code: integer ierr,istatus(MPI_STATUS_SIZE) leads to these errors: $ mpif90 -o simplex simplexmain579m.for simplexsubs579
