It is possible to follow the steps used to build the current version on Archer2. These steps are codified at the Archer2 github repository and include a number of dependencies to be built in the correct order:
$ git clone https://github.com/ARCHER2-HPC/pe-scripts.git $ cd pe-scripts $ git checkout cse-develop $ ./sh/tpsl/metis.sh --prefix=/path/to/install/location $ ./sh/tpsl/parmetis.sh --prefix=/path/to/install/location $ ./sh/tpsl/scotch.sh --prefix=/path/to/install/location $ ./sh/tpsl/mumps.sh --prefix=/path/to/install/location $ ./sh/tpsl/superlu.sh --prefix=/path/to/install/location $ ./sh/tpsl/superlu-dist.sh --prefix=/path/to/install/location $ ./sh/petsc.sh --prefix=/path/to/install/location
--prefixoption indicating the install directory should be the same in all cases. See the Archer2 github repository for further details (and options).
