Hi
after I finish execution, and all results are reported, and both
processes are about to call MPI_Finalize, I get this runtime error:
any help is appreciated, thanks
Manal
Signal:11 info.si_errno:0(Success) si_code:1(SEGV_MAPERR)
Failing at addr:0xa
[0]
Please see attached source file.
According to my understanding of MPI_Comm_spawn(), the intercommunicator
returned is the same as it is returned by MPI_Comm_get_parent() in the
spawned processes. I am assuming that there is one intercommunicator which
contains all the (spawned) child processes
That's excellent, thanks.

For lack of a longer explanation, let's call it "internal accounting
errors" :-). In an attempt to speed up the TM launcher, we made some
changes in Open MPI 1.1 which ended up using the TM API the wrong way.
So it was clearly a bug. It *might* work in 1.1, but I wouldn't
recommend it (i.e.,
Jeff,
What were the details of the problem/fixes?
Is it worth us moving to the trunk or using what we have until 1.1.1
arrives?
Thanks.

All --
Martin Schaffoner reported some TM problems to this list a little while
ago. It took a long time for he and I to synch up, but we finally
identified and fixed the problem. This only affects Open MPI 1.1
installs -- it is not an issue for 1.0.x installs. The fix has been
included in both
It might be ok to adapt the module to try to "include" it (vs. requiring
it) and if it's not there, fail over.
Make sense?

Hi ,
Can anyone please enlighten us about what really
happens in MPI_init() in openMPI?
More specifically i am interested in knowing
1.Functions that needs to accomplished during
MPI_init()
2.What has already been implemented in openMPI
MPI_Init
2. The routines called/invoked that perform
