Eric,
can you make your test case (source + input file + howto) available so i
can try to reproduce and fix this ?
I would like to, but the complete app is big (and not public), is on top
of PETSc with mkl, and in C++... :-(
I can for sure send you binaries if you have any of the following
plateforms (RedHat 6.6, openSUSE 13.1 , openSUSE 12.3 , Fedora 19,
RedHat 5.7 or openSUSE 11.3 ) and input files (maybe we could get it run
in a chrooted environnement? but I never tried this), but our source
code I don't think I can... but I would like to post a simple example
showing the problem...
Based on the stack trace, i assume this is a complete end user application.
have you tried/been able to reproduce the same kind of crash with a
trimmed test program ?
I am trying to do so right now... ;-)
I try to reproduce the very exact order for open/close of files by MPI
followed with "normal" open of the file, etc...
If I can reproduce the problem, I will send it immediatly to the list.
It is an intermittent problem, but valgrind seems to catch it every time!
I will work on this this evening and in the following days, hoping to
send it in time before the final release...
BTW, what kind of filesystem is hosting Resultats.Eta1 ? (e.g. ext4 /
nfs / lustre / other)
It is a local hard drive with ext4.
oh, just noticed that one of my mail didn't made it to the list... I
will try to resend it now... contains a few hints...
Merci! :-)
Eric
