In order to execute your program under MPI management, you'll need to use a command mpiexec.  The "easiest" way to do so would be to use the command line and launch your program manually.  For 8 cores, you'd want to use the command:

mpiexec -n 8 target.exe

Alternatively, after loading the MPI example, you'll see that the "Toolbox" menu should have a few new entries.  One entry is labeled "Launch with 4 Processes."  This toolbox command is pre-configured to launch the executable "target.exe" as 4 MPI-managed processes.  If you select "Configure Tools..." from that same menu, you can change the command used to launch your program under MPI management.

Any suggestions Jeff as to what I have done wrong on setup?  I did this on two machines and got the same results.  I also tried the hello world mpi I found at the above website, and it only grabs 1...

Sorry, I should have given you more data on the last reply!

I have an 8 core processor and I can see 4 cores responding - 1 core more than the others. But it says the number of processes is 1, so I am unsure how to interpret that.

Now I have to get it to work for multiple computers.  Any suggestions on reading that I can do?

I think you're misunderstanding how the Start tab's project offerings work.  To start the "MPI Example," you need to:

1.  Start Simply Fortran.

2.  In the Start panel, click "MPI Example."

3.  The file dialog opens asking you where you'd like to save your new project.  You'll need to type in a file name and save it to a valid directory.  You won't necessarily see any project files at this step since this is a "Save Project As..." dialog.

4.  Click Ok in the "Save Project As..." dialog after you've entered a filename.

After saving the project, you should now see, in the Project Outline panel, the following files:

• prime_mpi.f

• prime_mpi.f90

The project should build just fine.

Let us know if you have better luck!

Perhaps I've done something wrong?
