ompi_info is just the first time when an executable is built, and so it always
is the place where we find missing library issues. It looks like someone has
left incorrect configure logic in the system such that we always attempt to
build Infiniband-related code, but without linking against the l
I don't know anything about your application, or what the functions in your
code are doing. I imagine it's possible that you are trying to open statically
defined ports, which means that running the job again too soon could leave the
OS thinking the socket is already busy. It takes awhile for th
Here's another data point that might be useful: The error message is much more
rare if I run my application on 4 cores instead of 8.

Sorry for my last email - I think I spoke too quick. I realized after reading
some more documentation that OpenMPI always uses TCP sockets for out-of-band
communication, so it doesn't make sense for me to set OMPI_MCA_oob=^tcp. That

Hi there,
My application uses MPI to run parallel jobs on a single node, so I have no
need of any support for communication between nodes. However, when I use
mpirun to launch my application I see strange errors such as:

Hi Gus,
Thank you. I did start from a completely clean directory tree every time (I
deleted the whole folder and re-extracted the tarball).
I noticed that disabling any of the BTL components resulted in the same error,
so my solution was to build everything and disable certain components at

Yep - they are violating the C99 standard

Hi Dave --
It looks like my argv[argc] is not NULL (see below), so are we getting that
this problem is boost::python's fault?
Thanks!
Amos.
Looking in the boost code, I see this is how MPI_Init is called:
environment::environment(int& argc, char** &argv, bool abort_on_exception)
: i_initi
Looks like boost::mpi and/or your python "mpi" module might be creating a bogus
argv array and passing it to OMPI's MPI_Init routine. Note that argv is
required by C99 to be terminated with a NULL pointer (that is,
(argv[argc]==NULL) must hold). See http://stackoverflow.com/a/3772826/158513.
Afraid I cannot replicate a problem with singleton behavior in the 1.8 series:
11:31:52 /home/common/openmpi/v1.8/orte/test/mpi$ ./hello foo bar
Hello, World, I am 0 of 1 [0 local peers]: get_cpubind: 0 bitmap 0-23
OMPI_MCA_orte_default_hostfile=/home/common/hosts
OMPI_COMMAND=./hello
OMPI_ARGV=f
Okay, so regression-test.py is calling MPI_Init as a singleton, correct? Just
trying to fully understand the scenario
Singletons are certainly allowed, if that's the scenario

Can you pass us the actual mpirun command line being executed? Especially need
to see the argv being passed to your application.

Hi Lee-Ping
Did you cleanup the old build, to start fresh?
make distclean
configure --disable-vt ...
...
I hope this helps,

Hmm, the build doesn't finish - it breaks when trying to create the man page.
I guess I'll disable only a few specific BTL components that have given me
issues in the past.

Hi there,
I'm building OpenMPI 1.8.3 on a system where I explicitly don't want any of the
BTL components (they tend to break my single node jobs).
