Re: [ptp-dev] No process icons in Parallel Debug view
Jie,

I've never seen this problem with OpenMPI, and I don't have a
SLURM machine to run against.

Randy,

Not sure.

Will you please check the refactoring code for the potential reason?

Could this be a bug in my refactoring of the Process system?

Jie,

It sounds to me like the SLURM rms is somehow not creating the processes correctly. When you say you can see them in the JobsList view, do you mean the Processes panel of the Machines view? The JobsList view should just show a list of jobs. The Parallel Debug view should see the same processes that the Machines view sees, so I'm not sure why they're not visible. The debugger just manages changing the process state from running to suspended, so this should not be the source of the problem.

Greg,

Recently I'm testing PTP 4.0(RC4) on a cluster with about 1k nodes.
The cluster runs SLURM rms.

There is something strange (and potential bugs) with the PTP parallel debugger. 
When trying to launch a debug MPI job with 4 processes,  sometimes there are no
process icons within the Parallel Debug view. However, in the JobList view within Parallel Runtime perspective,
I can see that all four processes are RUNNING( GREEN icons). Without the process icons in the debug view,
many debug operations like registering process, creating process set are impossible.
However, even when process icons are missing, the stack trace of the (defaultly registered) first process is shown
in the Debug view.

I'm not very familiar with the new sdm debugger code.
Which debug event is responsible for the creation of process icons?
I remember that EVENT_DBG_SUSPEND is related to this issue.
Or is it related to the RMS proxy?
Does it mean that the SUSPEND event is lost?

Any idea?

Jie
