I guess we made some progress,however I think I still have a syntax problem.
Right now I am still configuring the master node ,so I do not have a hostfile
made yet.so I am using the following command which returns a python message
from an unknown python program.
mpirun --allow-run-as-root -np 4 hostname
the responds is :
python2helloworld.py
python2helloworld.py
python2helloworld.py
python2helloworld.py
this tells me that the program ran 4 times, 1 oer core.
this is good.
however I do not know where this program file is located. I also do not know
how this python 2 file gets invoked .
my question is :how can I modifly this command line to specifly the proper
python program?
thanks neil

Here are some instructions I have put together.
I am using Python 2 and Open MPI 2.1.2 so I changed the commands to work for
Python 3 and I tested them.
Hope it helps.
Regards,
Kostas

I am looking for a suggested list of commands to do this.

If your Linux distro does not have an Open MPI package readily available,
you can build Open MPI from source for an RPi fairly easily. Something like
this (not tested on an RPi / YMMV):
wget
https://download.open-mpi.org/release/open-mpi/v3.1/openmpi-3.1.0.tar.bz2
tar xf openmpi-3.1.0.tar.bz2
cd openmpi-3.1.0
./configure |& tee config.out
make -j |& tee make.out
sudo make install |& tee install.out
This will download, configure, build, and install Open MPI into the
/usr/local tree.
You can optionally specify a prefix to have it install elsewhere, e.g.:
./configure --prefix=/path/to/where/you/want/it/to/install |& tee config.out
Then do the make/sudo make again.

I am starting to build a Raspberry pi cluster with MPI and I want to use
the latest Raspian Streach Lite version from the raspberrypi.org website. After
a lot of trials of watching youtubes on how to do this, I have found that the
new version of Raspian Streach LITE is not compatible . I am looking for
details instructions on how to install MPIwith this latest version of Raspian
Streach Lite. I am using the newset hardware,RPI 3 B+ which requires this OS to
use the features on the -new chipset
Thanks
