Sorry you're having problems, Michele.
Updating: If you installed the "Eclipse IDE for Parallel Application Developers" ("package") and then did a Help > Check for Updates there probably aren't any updates to *that package.*
It's exactly what I did.
But then if you install PTP 5.0.7, from the PTP-specific update site, "already installed and will perform an update instead" is what it should say, yes.
It's exactly what happened.
I didn't read that link and I'll do it now, to double check what I did.
Right.
Can you launch and run from PTP/Eclipse?
Yes.
Can you debug a simple MPI 'hello world' program with the PTP Debugger?
I've not tried such a simple program ... I'll try on monday on the same machine where I had the problem.
I see you have OpenMPI 1.6
Greg may have other insights....

Yes, I've updated it.
A strange thing that happened was that when I tried to update the PTP from the Eclipse GUI, it did not update anything.
Then I tried to install PTP 5.0.7 and the installer told me that it was already installed and that it would have performed an update instead.
Then I separately downloaded the "proxy" package (v. 5.0.7) and built the sdm.
And I had the problem I described. Some more details. I'm using a Linux CentOS 5.x OS, on a x86_64 machine. I'm using Open MPI 1.6.
Thanks,
Best regards.

Hi Michelle,
I am not the best person to answer, but a problem I've already had was
not updating the SDM binary. Have you updated it along with PTP?
Best regards,
Rodrigo.
