mpicc is a symlink pointing to ompi_wrapper_script
I guess we do not correctly support the --target option, unless you changed
your configure options meanwhile, so you have to manually update the broken
symlinks so they point to arm-openwrt-linux-muslgnueabi-ompi_wrapper_script

Hi Gilles,
Thanks for responding me.
i did as mention previous mail ,but am getting below error as mpicc not
found...
*nmahesh@nmahesh-H81MLV3:~/Workspace/ARM_MPI/mpi$

You can try
configure --host=arm... CC=gcc_cross_compiler CXX=g++_cross_compiler

Rick,
if you look at the big picture, i think 3 communicators make more sense.
now keep in mind that a given task is only part of two valid communicators.
depending on how you implement communicator creation, there could be 2
communicators per task,
or 3 communicators, and one is MPI_COMM_NULL.

You should pass your arm architecture name to the --host option.
Example of my configure options for Open MPI, run on sparc64,
built on x86_64:

Hi all,
Thank you for responding me
Below is my configure options...
./configure --enable-orterun-prefix-by-default
--prefix="/home/nmahesh/Workspace/ARM_MPI/openmpi" \

CXX=arm-openwrt-linux-muslgnueabi-g++ \
--host=arm-openwrt-linux-muslgnueabi \
Hi Gilles,
Thank you for reply,
After doing below config options also
./configure --enable-orterun-prefix-by-default
--prefix="/home/nmahesh//home/nmahesh/Workspace/ARM_MPI/armmpi/openmpi"
CC=arm-openwrt-linux-muslgnueabi-gcc
CXX=arm-openwrt-linux-muslgnueabi-g++
Hi George and Jeff,
Thank you for taking the time to respond to my query. You did inspire me in the
right direction. Some of the variables involved in the calculation of B were
not broadcast. In addition,
a double do-loop combined with an IF statement was overwriting on the correct
B values.
Hi,
can you please give the patch below a try ?
Cheers,
Gilles

I have the release version of CUDA 8.0 installed and am trying to build OpenMPI.
Here is my configure and build line:
./configure --prefix=$PREFIXPATH --with-cuda=$CUDA_HOME --with-tm=
--with-openib= && make && sudo make install
Where CUDA_HOME points to the cuda install path.
When I run the
Hi,
You did *not* specify the following options to configure, right?
Specifying all these will cause a problem.
--disable-mmap-shmem
--disable-posix-shmem
--disable-sysv-shmem
Please send the output of the following command.
mpirun --allow-run-as-root -np 1 --mca shmem_base_verbose 100
After looking into this a bit more it appears that the issue is I am building
on a head node which does not have the driver installed. Building on back node
resolves this issue. In CUDA 8.0 the NVML stubs can be found in the toolkit at
the following path: ${CUDA_HOME}/lib64/stubs
For 8.0
