Turned out it was the fftw package that was not installed perfectly.
I used the fftw package that came with QE as suggested and all went fine.
Thanks a lot.

Hi Jitendra
Before you worry too much about the inefficiency of using a contiguous
scratch buffer to pack into and send from and a second contiguous scratch
buffer to receive into and unpack from, it would be worth knowing how
OpenMPI processes a discontiguous datatype on your platform.

George,
Yes that's what I understood after struggling with it over a week. I
need to send such messages frequently so creating and destroying the
data type each time may be expensive. What would be the best alternative
for sending such malloced data ? Though I can always pack the data in a
long arr
Jitendra,
You will not be able to reuse the same data-type. All internal arrays
are malloced and their position in memory will be completely random
from call to call (or use to use of the data-type). Therefore, even if
your structure looks the same, as you use non static arrays in your
st
Ralph,
Thanks!
I checked output of "ompi_info" and found that OpenMPI on PowerPC is
not built with heterogeneous support. We will rebuild OpenMPI and then
try the command you suggested.

First, I trust that you built Open MPI to support heterogeneous
operations? I'm not sure what version you are using, but it may well
have done it by default.
Second, there is an error on your cmd line that is causing the
problem. It should read:
mpirun -np 1 -host b1 foo_x86 : -np 1 -host
I have one MPI job consisting of two parts. One is "foo_x86", the other
is "foo_ppc", and there is MPI communication between "foo_x86" and
"foo_ppc".
"foo_x86" is built on X86 box "b1", "foo_pcc" is built on PPC box
"b2".Anyone can tell me how to start this MPI job?
I tried "mpiru

There was a bug that caused ompi-checkpoint not to find the correct
place in the session directory for mpirun's contact file. This was
fixed in r19265, so you should no longer have a problem.

Hi Gabriele!
In this case, mpirun works well, but the checkpoint procedure fails:

Dear OpenMPI developers,
i'm testing checkpoint and restart with OpenMPI 1.4 nightly. Test machine is

At the moment, I have some problems. My application is a simply
