Hi Wyatt, All,
Just to bring this
discussion to the g-Eclipse mailing list as I think also others are interested
in it …
Wyatt, Greg and Beth, please feel free to subscribe to our list
since it would be great to let further discussions directly go on there, we
already subscribed to the ptp-dev and
will definitely make use of it in the future ;-)
Best regards,
Mathias

Betreff: Re: MPI Trace
Visualization
That is excellent, thank you. You have a Java based OTF trace
reader? That could come in very handy
as well. I developed one for the TAU (http://www.cs.uoregon.edu/research/tau/home.php)
trace format which might be of use if you are interested in supporting more
formats.
Regards,
Wyatt

Hi Wyatt
We talked to Mathias and it should
be no problem to create a feature that
provides the trace visualization functionality.
The trace visualization provides following extension points:
- Trace reader:
Currently we support traces in the formats NOPE and
OTF (but the OTF support
is only very basic).
- Trace visualization:
Right now there are plugins for visualization using Lamport clocks,
physical
clocks (still in a early stage) and
a very basic demonstration plugin
for displaying statistics using BIRT.
- Actions:
Its possible to define actions for the context menu of the events in the
graphs. There a few simple implementations.
- Markers:
Markers change the appearance of the events in the traces. They can be used
to mark events of interrest.
We are currently cleaning up the
code a bit and will commit an updated version
soon to our CVS in Karlsruhe (it is not yet in the Eclipse.org repository).
As far as threaded MPI applications are concerned, we currently do not offer
support for that since we mainly use NOPE traces and
those have no support
for threads. Depending on what your traces look like it might be possible to
add a trace reader for that.
Some other people in g-Eclipse told me that they are also interested in the
possibilities to use the trace view outside of g-Eclipse. I propose to
continue the discussion on the g-Eclipse mailing list:
