Raspberri Pi MPICH 4.1a1

Building and installing mpich-4.1a1 on a Raspberry Pi 4. The build is done in /opt/hpc/rpi/mpi/mpich/4.1a1/bld and the install location is /opt/hpc/rpi/mpi/mpich/4.1a1 to control the version usage of mpich.

As root

aptitude install gfortran automake g++ make
mkdir -p /opt/hpc/src
chown -R $USER.$USER /opt/hpc

As user

export VER=4.1a1
cd /opt/hpc/src
wget https://www.mpich.org/static/downloads/$VER/mpich-$VER.tar.gz
export PFX=/opt/hpc/rpi/mpi/mpich/$VER
mkdir -p $PFX/bld
cd $PFX/bld
tar xvzf /opt/hpc/src/mpich-$VER.tar.gz --strip-components=1

On traditional HPC systems the device must match the network. Without specification it might look like this:

./configure --prefix=$PFX
...
*****************************************************
***
*** device      : ch4:ofi (embedded libfabric)
*** shm feature : auto
*** gpu support : disabled
***
  MPICH is configured with device ch4:ofi, which should work
  for TCP networks and any high-bandwidth interconnect
  supported by libfabric. MPICH can also be configured with
  "--with-device=ch4:ucx", which should work for TCP networks
  and any high-bandwidth interconnect supported by the UCX
  library. In addition, the legacy device ch3 (--with-device=ch3)
  is also available.
*****************************************************
Configuration completed.

With using the legacy ch3:sock device it looks like this:

./configure  --prefix=$PFX --with-device=ch3:sock
...
*****************************************************
***
*** device configuration: ch3:sock
***
*****************************************************
Configuration completed.

If you are following these various configure experiments, make sure you run configure from a clean archive before compiling.

make -j 4
make install
