Hello,
I have a small test case where a file created with MPI_File_open
is still open at the time MPI_Finalize is called. In the actual
program there are lots of open files and it would be nice to avoid the
resulting "Your MPI job will now abort." by either having MPI_Finalize

Thanks for the quick response ... I've been thinking about this today and tried
a few things on my CentOS mini connected cluster ...
To use tcp btl I will have to set up a bridge on A with ib0 and ib1
participating in the bridge, then tcp btl could be used as you suggest.
Unfortunately, the

No MPI involved. Fine. The objective is to parallelize.
I want to keep the GUI(windows) as the control to start calcs and display
results.
The GUI could be the master process of the mpi processes.
That's
Thanks for tracking that down!
Here's where it was removed:
https://svn.open-mpi.org/trac/ompi/changeset/23434
and then it was later applied to the v1.4 branch in r23448.
I'll double check back with Ralph (the ORTE guy), but I don't think that this
change matters.

You have no idea. :-)
The MPI Forum has been debating about exactly this issue for over a year. It
turns out to be a surprisingly complex, subtle issue (i.e., it's

This looks like something the boost people will have to support you with -- we
don't know anything about their installer.
Sorry! :(

Other than MPI_COMM_SPAWN[_MULTIPLE], we don't expose the underlying run-time
to MPI applications.
There is a whole programatic interface for the layer under MPI (the Open MPI
Runtime Environment -- ORTE), though. We don't advise mixing ORTE calls in MPI
applications, but it is certainly
You're gonna have to use a protocol that can route through a machine,
OFED User Verbs (ie openib) does not do this. The only way I know of to
do this via OMPI is with the tcp btl.

We've been using OpenMPI in a switched environment with success, but
we've moved to a point to point environment to do some work. Some of
the nodes cannot talk directly to one another, sort of like this with
computers A,B, C with A having two ports:
A(1)(opensm)-->B
A(2)(opensm)-->C
No way!!! That is so limiting,
