[ptp-user] PTP and valgrind
|
Hi,
I just tried to deploy valgrind from within a Eclipse PTP session. My mileage
varied a lot. Eventually, I ended up using valgrind from command line.
This is what I found. Did I overlook something important ?
* There is an Eclipse plugin for valgrind (as part of the Linux tools
package), but it appears to support only serial (C/C++ ?) applications.
(and it is also sprouting java NPEs).
* There seems to be the external tools framework
(http://wiki.eclipse.org/PTP/ETFw/PTP_External_Tools_Framework),
which is not a valgrind plugin, but a framework for building such a
plugin. Suspiciously, at the end of the wiki page, the text refers to PTP 3.0
release plans - and we are at PTP 7.0, correct ? Also the wiki page seems to
be in category "Pages with broken file links". Is this framework still
maintained ?
* Skimming through the documentation of the latter, a large portion appears to
be dedicated to building a GUI for specifying tool configurations. I would be
rather interested how to interpret the results. -- Or even better, how to feed
the results (from a single MPI rank) into the valgrind plugin mentioned above.
* When I said "command line", I actually meant the following. In an OpenMPI
interactive launch configuration, I set the application name to
"/usr/bin/valgrind" and pre-pended the application name (=compiled binary from
the the PTP project) to the argument list. --- That worked and placed the
shuffled output lines of size_of_MPI_COMM_WORLD valgrind sessions into the
Eclipse console. Question - How to un-shuffle the output lines and feed it into
the valgrind profiling display ?
