Re: [ptp-user] PTP parallel debugging on OS X 10.8

Hi Tomasz, sorry you are having trouble.
Let's start at the beginning. Sounds like you are running MPI locally on your Mac. What version of MPI do you have? (OpenMPI?)  
See http://wiki.eclipse.org/Parallel_Tools_Platform_FAQ#Q:_How_do_I_install_Open_MPI.3F
Can you compile and run a small mpi program from the command line?

Hi

I spent today having my second go on trying to do MPI debugging with PTP on OS X. A year ago tried on Darwin (and failed - but perhaps did not try hard enough). Today it was on the newest 10.8.2 system.

What I did:

1. Installed the newest Eclipse 6.0.2
    => This is done in to my $HOME/Devel/eclipse
2. Installed the PTP-specific update as mentioned on http://www.eclipse.org/ptp/downloads.php
    => I did only this update and tried to debug MPI Hello world - but it did not work (details below)
    => Then I noticed that "Check for Updates" still shows one possible "parallel environment update" which I also installed
          (MPI Hello wouldn't still work)
   => Q1: Should I go only for the PTP-specific update or should I install all possible updates?
3. Before trying to debug anything I installed sdm (downloaded newest ptp-proxy):
   => First I compiled sdm in my temp directory and moved the "bin/sdm" directory into my eclipse directory (and used this path)
   => Then I found out that the user documentation says:
             
              If you are debugging on the local machine, this path should point to the sdm executable in your Ecilpse installation'splugins/org.eclipse.ptp.os.arch_version/bin directory, where os.arch_version is your operating system (linux, macosx, or aix), architecture (x86, x86_64, or ppc), and version number of the plugin (e.g. 5.0.0.201106080812).

        So on one of the subsequent todays reinstallations of eclipse I actually unzipped ptp-proxy and compiled and left it there. This also did not work.
 
4. Just to add the: ssh server is enabled on my laptop and I can "log into it" from eclipse when initialising the parallel debug environment.

When I try to debug the auto-generated MPI Hello world program, I am getting this error:

26ee4d88-e731-4750-8938-59a7872ca44f: FAILED
#PTP job_id=36436

--------------------------------------------------------------------------
mpirun noticed that the job aborted, but has no info as to the process
that caused that situation.
--------------------------------------------------------------------------

Running the application in parallel works. Debugging it in serial mode also seems to work. I would appreciate some hints on why doesn't parallel debugging just work?

Best regards,
