Hi,
I got a problem with ompi when sending large number of messages from

Process A only send... and B only receive (the buffers are reused)

Newbie question:
How is the message passing of Open-MPI implemented when I have
say 4 nodes with 4 processors (SMP) each, nodes connected by a gigabit
ethernet ?... in other words, how does it manage SMP nodes when I

When building the nasa overflow 2.0aa code with openmpi 1.1.1b3 using
the intel compilers on a Opteron cluster running
SLES 9 with the intel 9 compilers, I get the following warnings when
linking :
/acct/bsb3227/openmpi_1.1.1b3/bin/mpif90 -xW -O2 -convert big_endian
-align all
-o overmpi_intel90_6
Summary: You have to properly uninstall OpenMPI 1.0.2 before
installing OpenMPI 1.1
