Interestingly enough, I have found that using --disable-dlopen causes
the seg fault whether or not --enable-mca-no-build=coll-ml is used. That
is, the following configure line generates a build of Open MPI that will
*not* seg fault when running a simple hello world program:

Hi Nate,
The odls output helps some. You have a really big CLASSPATH. Also there
might be a small chance that the shmem.jar is causing problems.
Could you try undefining your CLASSPATH just to run the test case?
If the little test case still doesn't work, could you reconfigure the mpi
build to

David, to modify that option modify the toss-common file. It is in the
same location as the platform file. We have a number of component we
disable by default. Just add coll-ml to the end of the list.

Ah, if you're disable-dlopen, then you won't find individual plugin DSOs.
Instead, you can configure this way:
./configure --enable-mca-no-build=coll-ml ...
This will disable the build of the coll/ml component altogether.

Hi Ehsan
You didn't tell the details of how you configured and installed Open MPI.
However, you must point the configuration --prefix to the installation
directory, say:
./configure --prefix=/opt/openmpi-1.8.8
In addition, the installation directory must be *different* from the
directory where
David, our platform files disable dlopen. That is why you are not seeing
any component files. coll/ml is built into libmpi.so.

Hey Jeff,
I'm actually not able to find coll_ml related files at that location.
All I see are the following files:
[dshrader@zo-fe1 openmpi]$ ls
/usr/projects/hpcsoft/toss2/zorrillo/openmpi/1.8.8-gcc-4.4/lib/openmpi/
libompi_dbg_msgq.a libompi_dbg_msgq.la libompi_dbg_msgq.so

I don't have that option on the configure command line, but my platform
file is using "enable_dlopen=no." I imagine that is getting the same
result. Thank you for the pointer!
Thanks,
David

Hi all,
The configuration might be a bit exotic:
Kernel 4.1.5 vanilla, Mellanox OFED 3.0-2.0.1
ccc174 1 x dual port ConnectX-3
mini4 2 x single port ConnectX-2
mini2 8 x single port ConnectX-2

The following does work:

Note that this will require you to have fairly recent GNU Autotools installed.
Another workaround for avoiding the coll ml module would be to install Open MPI
as normal, and then rm the following files after installation:
rm $prefix/lib/openmpi/mca_coll_ml*
This will physically remove the co
David,
i guess you do not want to use the ml coll module at all in openmpi 1.8.8
you can simply do
touch ompi/mca/coll/ml/.ompi_ignore
./autogen.pl
./configure ...
make && make install
so the ml component is not even built
Cheers,

Ehsan,
how did you try to install openmpi ?
shall i assume you download a tarball, and ran configure && make install ?
can you post the full commands you ran ?
are you installing as root ? or did you run sudo make install ?
if not, do you have write access to the /opt/openmpi-1.8.8 directory ?
hi,
my dear friends
i tried to upgrade my openmpi version from 1.2.8 to 1.8.8
