Forgive me for chipping in here. There is definitely a momentum behind the ARM architecture in HPC. However it seems to me that there are a lot of architectures under the 'ARM' umbrella. Does anyone have a simplified guide to what they all mean? On 30 May 2018 at 02:26, Gilles Gouaillardet

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
