[AMD Official Use Only - Internal Distribution Only]
After downloading a particular openMPI version, let's say v3.1.1 from
https://download.open-mpi.org/release/open-mpi/v3.1/openmpi-3.1.1.tar.gz , I
follow the below steps.
./configure --prefix="$INSTALL_DIR" --enable-mpi-fortran --enable-mpi-cxx
--enable-shared=yes --enable-static=yes --enable-mpi1-compatibility
make -j
make install
export PATH=$INSTALL_DIR/bin:$PATH
export LD_LIBRARY_PATH=$INSTALL_DIR/lib:$LD_LIBRARY_PATH
Additionally, I also install libnuma-dev on the machine.
For all the machines having Ubuntu 18.04 and 19.04, it works correctly and
results in expected performance/GFLOPS.
But, when OS is changed to Ubuntu 20.04, then I start getting the issues as
mentioned in my original/previous mail below.

[CAUTION: External Email]
How are you installing the OpenMPI versions? Are you using packages which are
distributed by the OS?
It might be worth looking at using Easybuid or Spack

Dear Experts,
Until recently, I was using openMPI3.1.1 to run single
node 128 ranks MPI application on Ubuntu18.04 and Ubuntu19.04.
But, now the OS on these machines are upgraded to Ubuntu20.04, and I have been
observing program hangs with openMPI3.1.1 version.
So, I tried with openMPI4.0.5 version - The program ran properly without any
issues but there is a performance regression in my application.
Can I know the stable openMPI version recommended for Ubuntu20.04 that has no
known regression compared to v3.1.1.
