Re: [ptp-user] debug in parallel

That may or may not be a problem. Let’s try this first. Can you edit ~/.eclipsesettings/rms/MPICH2/start_debug_job.pl and add ‘(int)’ to the line that prints ‘MPIR_debug_state' (line 108)?
After the change it should read:
$response = $gdb->get("print (int) MPIR_debug_state");
Regards,
Greg
