rank ordering for basic otf2 #10

Open wohlbier opened 6 years ago

Is there a reason that ranks are not ordered sequentially in the trace view? See attached image.

Hmm... the full version of Ravel will re-order the ranks to group ones communicate with each other over ones that do not. I thought I tore that out for the basic version and the normal Gantt version though.

It could also have something to do with the way the trace was written or the way the sub-communicators are set up. It may be trying to preserve the sub-communicator order (but still label by the global ranks).

Short answer: Several possibilities. Should we take a look? I have a student who just started working on it with plans to add more filtering/summary views.

You're welcome to the data. The tgz file is 380MB. Do you have anywhere to put it?

Thanks! You can place it here: https://www.dropbox.com/request/RvoTM5HKFTlAVsU4jRT5 (I'll close the link after you do.)
