Re: [ptp-dev] Process sets? Process output?

Should running and stepping process sets work ok right now?
Yes, with one caveat. There's a bug in gdb on Linux that stops the
'suspend' button from working. I'll try and fix that today.
And should the output in the jobx_processY view work?
When you run a job it should. Currently there is something preventing
output when you are debugging a process.
(I go to runtime persp. to get them - dclick on node/process icons...
then go back to debug view and i can see them there.
I want to step over printlns so i can "prove" a particular process
is running. Should that work?)
Not currently. Usually just showing the location changing and the
values of variables is enough for a demo.
Running and stepping process sets were a bit dicey last night when
i played around more, too.
If you can suggest a simple MPI program and a scenario that works,
I will try that.
I would suggest creating a section in your program that doesn't do
any sends/receives and do your breakpoints/stepping demos there. That
way you will avoid deadlocks in the communication code. I find
stepping all processes through your 'if' statement works fine. You
see the different instruction streams and then eventually everything
resyncs at the MPI_Finalize().
Leaving for the meeting now. Hopefully I can find a wired connection
so this Linux version of my thinkpad can connect. I don't have the
wireless
working on it yet. Demo at 4pm CT.
Thanks for all your help so far, guys!
