"Soon". With so many different organizations working together, it's
difficult to predict the exact date.
Hi Jeff,
sorry for the delay. When i have little time, i'll check OMPI trunck with
bound checking.
When is the deliver date of 1.3 version?

I think yes.
How does one do so? It may be worthwhile to expand our support for
gcc bounds checking (i.e., beyond just valgrind). The valgri

Were you checking only with the OMPI 1.2 series? If so, is there a
chance you could test with the OMPI tru

Just a moment:
i didn't compile OpenMPI with bounds checking, but only my application.
Problems with OMPI compiled with bound checking remains.

This is probably not too surprising -- the IB driver gives back memory

Hi Jeff,
i compiled OpenMPi using xgcc 4.0.2. I noted that the program stops before
to do process spawn.
Very strange.

I'm afraid that we've never tested OMPI under these conditions; I
don't know exactly what xgcc is testing for, so I don't know why it
would fail. There could be weird interactions between the OFED stack
and xgcc...? (i.e., memory "appears" from the kernel via ibv_*
function calls, etc.)
Hi Open MPI developers,
I compiled OpenMPI 1.2.6 with xgcc, a gcc version with bounds-checking
support. But i have a problem with a simply MPI application compiled with
-fbounds-checking flags.
The job doesn't works and it is locked to MPI_Init(), doing nothing. It is a
very strange behaviour. I
