I have some old memory of this where the .bashrc file and the .profile are
distinguishing login and non-login.
Also something to do with the - being an argument to the bash process or
something like this.
man bash would give you a definite answer.

Hi
Will MPI_Probe return that there is a message pending reception if the
sender MPI_Bcast a message?
Is the only way to receive a broadcast from the root is to call MPI_BCast in
the slave?
ditto,

Hello
Do people looking at this list ever join the #openmpi IRC channel. The channel
seems to point to the website already.
The medium could be useful to spread even more the use of openmpi.
More specific channels could also be created. -beginner, -platform specific ,

I don't understand 1 thing though and would appreciate your comments.
In various interfaces, like network sockets, or threads waiting for data from
somewhere, there are various solutions based on _not_ checking the state of the
socket or some sort of queue continuously, but sort of getting _in
very clear, thanks very much.

Hello,
on win32 openmpi 1.4.3, I have a slave process that reaches this pseudo-code
and then blocks and the CPU usage for that process stays at 25% all the time (I
have a quadcore processor). When I set the affinity to 1 of the cores, that
core is 100% busy because of my slave process.

Does this really mean the process cannot have any other threads at all, even if
they doen't deal with MPI at all?
I'm curious as to how this case affects the openmpi implementation?
Essentially, what is the difference between MPI_THREAD_S

It truly does help to know what version of OMPI you are using - otherwise,
there is little we can do to help

Hello
If I have a 256 mpi processes in 1 communicator, am I able to split that
communicator, then again split the resulting 2 subgroups, then again the
resulting 4 subgroups and so on, until potentially having 256 subgroups?
Is this insane in terms of performance?

No way!!! That is so limiting,
Are you aware of any MPI implementation that is able to do both windows and
linux?

Hi Hicham,
Unfortunately, it's not possible to run over both windows and linux.

Hi,
One typically uses mpirun to launch a set of mpi processes.
Is there some programmatical interface to launching the runtime and having
the process that launched the runtime becoming part of the list of mpi
