Hi,
I have made some other tests. I don't know if it can help you but here is what
I observed.
Using the array contructor [] solves the problem for a scalar, as someone wrote
on
the mpi_f08 bindings and the Intel 2016 compilers.
It looks like configure is choosing to generate a different pragma for Intel
2016 vs. Intel 2015 compilers, and that's causing a problem.
Let me look into this a little more...

Open MPI was configured with the same options with both compilers.
Do you have any idea how I could solve this problem?

naged to hit on this solution by guesswork, but it's quite a
relief to know that its correctness is actually mandated by the MPI
standand not just my dumb luck.
Thanks again,

case I'm seeing failures with both MPICH2 and

would be appreciated. If there's anything I can do to make the issue
easier to replicate please let me know.

I've attached the logs for my "configure" and "make all" steps. Our email

Hi all,
I'm trying to compile openMPI 1.4.2 in Cygwin 1.7.5-1.
After ./configure I do make and after some time I always get this
error. I've tried "make clean" and "make" again, but that doesn't
help. It looks to me like I have all the requirements of the

omatically picks up the PE_NODEFILE if it detects that it is launched
within an SGE job. Would it be possible to have the same functionality for
torque? The code looks a bit too complex at first sight for me to fix this
myself.
Best regards,

Hi,
I was trying to install openmpi-1.2.2 under 2.4.32 kernel.
./configure --prefix=/mnt/shared/jroy/openmpi-1.2.2/ CC=icc CXX=icpc
F77=ifort FC=ifort
make all install
It installed successfully, but during mpirun I got...
mpirun --mca btl_tcp_if_include eth0 -n 4 -bynode -hostfile test_nodes
.
Dear Rainer and Adrian,
Thank you lot for the help. It works. I was trying this for long time but
didn't notice the mistakes. I can't understand how can I overlooked that!

In my 4 nodes cluster I want to run two MPI_Reduce on two communicators (one

Hi,
To optimize our network throughput we set jumbo frame=8000. The transfers
are going smoothly. But after few minitues we are seeing drastic drop in
network throughput, looks like a problem of deadlock in network transfer
speed (slow down by a factor of 100!). This situation is not happening if

Hi,
In between two nodes I have dual Gigabit ethernet full duplex links. I was
doing benchmarking using non-blocking MPI send and receive. But I am
getting only speed corresponds
