Hi,
I would like to know what are the algorithms used in MPI_BCast() in the OpenMPI
implementation.
For example, in MPICH2, depending on the number of processes and the size of
data to broadcast, the broadcasting algorithm used can be different : a
binomial tree if the message is short or MP
Is the path correct for the new location?

Hi again,
as I checked the mailing list - isn't it this bug showing up again in static
version ?

Greetings,
I prepared my own static OpenMPI files (mpirun, mpif90...) within
openmpi-1.6.1.tar.gz
./configure --prefix= --without-memory-manager CXX=icpc CC=icc
F77=ifort FC=ifort LDFLAGS=--static --disable-shared --enable-static
and I was trying to launch parallel job at other machine (I sp
It isn't possible to do so.

Hello, I found a problem in openmpi's ptmalloc2. The problem is that
TSD (thread specific data) does not work properly and it may cause
peformance loss and segfault. In my case, heavy memory allocating
applications sometimes make segfault.
Please see opal/mca/memory/linux/sysdeps/pthread/malloc-
When i use the function comm_spawn ,it can not to be work on an off-line host.
but it can run well when the network is connected using a fault configure.
on the page http://www.open-mpi.org/community/lists/users/2010/01/11825.php
it says"Shared memory doesn't extend between comm_spawn'd parent/
