I will be out of the office starting 12/21/2008 and will not return until
01/02/2009.
So your tests show:
1. "Shared library in FORTRAN + MPI executable in FORTRAN" works.
2. "Shared library in C++ + MPI executable in FORTRAN " does not work.
It seems to me that the symbols in C library are not really recognized by
FORTRAN executable as you thought.What compilers did
Where did you put the environment variable related to MCF licence file and
MCF share libraries?
What is your default shell?
Did you test indicate the following?
Suppose you have 4 nodes,
on node 1, " mpirun -np 4 --host node1,node2,node3,node4 hostname" works,
but "mpirun -np4 --host node1,no
which
could be the right one ;-)
Thanks in advance for your hints, Best Regards, Gilbert.

can you update me with the mapping or the way to get it from the OS on the
Cell.
thanks

Hi, Lenny,
So rank file map will be supported in OpenMPI 1.3? I'm using OpenMPI1.2.6

1. MCA BTL parameters
With "-mca btl openib,self", both message between two Cell processors on
one QS22 and messages between two QS22s go through IB.
With "-mca btl openib,sm,slef", message on one QS22 go through shared

. Seems to me SEND/RECV is
always used no matter btl_openib_flags is. Can I force OpenMPI to use
RDMA between x86 and PPC? I only transfer MPI_BYTE, so we do not need
the support for endianness.

Ralph,
How does OpenMPI pick up the map between physical vs. logical
processors?Does OMPI look into "/sys/devices/system/node/node for
the cpu topology?
Thanks,

ts (which would
default to whatever node you were on when you executed this), while
foo_ppc will run on both hosts b1 and b2 (which means the first rank
will always go on b1).
Hope that helps

"b2".Anyone can tell me how to start this MPI job?
I tried "mpirun -np 1 foo_x86 : -np 1 foo_ppc -H b1,b2"
I tried the above command on "b1", the X86 box, and I got "foo_ppc:
Exec Format error"
I tired on "b2", the PPC box, and I got "foo_x86: Exec format error"
Anybody has a clue? Thanks in advance.
