Hey all,
I'm getting a segmentation fault when I attempt to receive a single
character via MPI_Irecv. Code follows:
void recv_func() {
if( !MASTER ) {
charbuffer[ 1 ];
int flag;
The following is the error dump

Hi
I am trying to run open-mpi 1.3.3. between a linux box running ubuntu
server v.9.04 and a Macintosh. I have configured openmpi with the
following options.:
./configure --prefix=/usr/local/ --enable-heterogeneous --disable-shared
--enable-static
When both the machines are connected to the
Continuing the conversation with myself:
Google pointed me to Trac ticket #1944, which spoke of deadlocks in
looped collective operations; there is no collective operation anywhere
in this sample code, but trying one of the suggested workarounds/clues:
that is, setting btl_sm_num_fifos to at
Thank you, but I don't understand who is consuming this information for
what. E.g., the mpirun man page describes the carto file, but doesn't
give users any indication whether they should be worrying about this.

I hate to repost, but I'm still stuck with the problem that, on a
completely standard install with a standard gcc compiler, we're getting
random hangs with a trivial test program when using the sm btl, and we
still have no clues as to how to track down the problem.

Hi Eugene,
carto file is a file with a staic graph topology of your node.
in the opal/mca/carto/file/carto_file.h you can see example.
( yes I know that , it should be help/man list :) )
Basically it describes a map of your node and inside interconnection.
Hopefully it will be discovered
As Ralph suggested, I *reversed the order of my PATH settings*:

The ib tunings that you added to your command line only delay the
problem but doesn't resolve it.
The node-0-2.local gets asynchronous event "IBV_EVENT_PORT_ERROR" and as
result
the processes fails to deliver packets to some remote hosts and as
result you see bunch of IB errors.

Are you saying the output of mpicc/mpif90 -show has the same
optimization flags? MPICH2 usually puts it's own optimization flags
into the wrappers.
Jed, thank you for your reply. Yes, mpif90 shows (other than differing
libraries) identical flags.
