Re: [ptp-user] Problem Debugging MPI program PTP

[David Wootton <drwootton@xxxxxxxxxx>]

Hi
I just tried this with the latest PTP code and it runs for me. What version of MPICH are you running? Do you remember what perl errors you got and how you fixed them?

It looks like this is failing when the script which starts the debugger is trying to read an internal MPICH structure to figure out the task mapping?

I'm traveling this week so I most likely won't be able to get back to this for a few days.

Hello,

(My apologies for re-posting but some gibberish appeared while copying my configurations, so I have tried to clean it up.)

I am trying to use PTP/Eclipse for debugging my MPI programs. Currently, I am testing the sample PI calculation program by running it Local. While the program runs fine with a parallel "Run" configuration for the local system, I keep getting the following error when trying to debug it. The error I get is:

d4317265-02aa-4af6-91a4-52a73966900f: FAILED
Use of uninitialized value $response in pattern match (m//) at /root/.eclipsesettings/rms/MPICH2/start_debug_job.pl line 150.

Error reading MPIR_proctable at /root/.eclipsesettings/rms/MPICH2/start_debug_job.pl line 66.

My configurations are:
Eclipse Standard/SDK (Version: 4.4.0.20140612-0500)
Eclipse Platform  (Version: 4.4.0.v20140606-1558)

Eclipse for Parallel Application Developers (Version: 8.0.0.201406102209)
Eclipse C/C++ Development Tools (Version: 8.4.0.201406111759)
Ubuntu 12.04 LTS

Before getting this error, I received a couple of Perl errors, which i resolved by updating some of the perl packages.

Any insight/help will be much appreciated.

Thanks
