Now that we’ve built a cluster, let’s install UFS:
We’re going to install UFS on the HeadNode, we’re able to do this as the architecture of the HeadNode instance type,
c6a.2xlarge, matches the compute nodes so Spack does the correct microarchitecture detection. In most other cases it makes sense to install on compute nodes.
spack install -j $(nproc) ufs-weather-model%intel^intel-oneapi-mpi+external-libfabric EOF
||Compile with all cores on the instance.|
||Specify the Intel Compiler (icc) we installed in e. Install Intel Compilers.|
||Uses Intel MPI which we added in e. Install Intel MPI|
This will take about 1 minute to install. While that’s installing feel free to advance to the next step and pull down the simple test case.
