Re: [ptp-dev] Only single MPI task appears in debugger view

[Dave Wootton <dwootton@xxxxxxxxxx>]

That explains why I was able to make
it work a week ago and couldn't make it work any more. Now I can switch
between tasks. The first time I do this, the debug view then shows me task
0 and task 1 in suspended state. I then double click again on the task
0 icons then task 1 icons I got a core file with the following traceback
for the SDM. I modified the makefiles to compile without -O2 so the traceback
should be good.

Dave,

You need to double click on the icon to register it in the debug view.
