But I am compiling Open MPI with --without-memory-manager, so it should work?
Anyways, I ran the tests and valgrind is reporting 2 different (potentially
related) problems:
1.
==12680== Invalid read of size 4
==12680==at 0x709DE03: ompi_cb_fifo_write_to_head
(ompi_circular_buffer_fifo.h:271
@#$%@#$%
Someday, I'm going to learn to send to the right list. Sigh.
Well, if anyone here cares, there's a slowly-getting-there web site
for MTT going up... :-)

I fixed the left-hand navigation, put up some descriptive text, and
then copped out and linked to the wiki for all the real content. :-)

I will be out of the office starting 09/21/2007 and will not return until
10/01/2007.
I will respond to your message when I return.
Thanks George. I figured out the problem (two of them actually) based
on a pointer from Gleb (thanks Gleb). I have two types of send queues
on the UD BTL -- one is per-module, and the other is per-endpoint. I
had missed looking for stuck frags on the per-endpoint queues.
So something is wro
Excellent -- thanks.

Andrew,
There is an option on the message queue stuff, that allow you to see
all internal pending requests. On the current trunk, edit the file
ompi/debuggers/ompi_dll.s at line 736 and set the p_info-

restart totalview. Yo
Tim,
Valgrind will not help ... It can help with double free or things
like this, but not with over-running memory that belong to your
application. However, in Open MPI we have something that might help
you. The option --enable-mem-debug add a unused space at the end of
each memory alloca

Thanks for the suggestions. I reran the runs with --without-memory-manager and
got (on 2 of 5000 runs):
*** glibc detected *** corrupted double-linked list: 0xf704dff8 ***
on one and
*** glibc detected *** malloc(): memory corruption: 0xeda00c70 ***
on the other.
So it looks
Per an idea that came up recently, can we make it so that ompi_info
reports the version of VT that is integrated into Open MPI?
