Notus relies on the ADIOS and HYPRE libraries. Optionally, Notus relies on MUMPS, LIS, ADIOS2, HDF5, T3PIO libraries

Some libraries may depend to other libraries:

ADIOS: parallel I/O (website)
- Mini-XML: xml parser used by ADIOS (website)
HYPRE: high-performance iterative solvers (website)
- BLAS: Basic Linear Algebra Subprograms (website)
- LAPACK: Linear Algebra PACKage (website)
MUMPS: high-performance direct solver (website)
- METIS: Serial Graph Partitioning and Fill-reducing Matrix Ordering (website)
- ScaLAPACK: Scalable Linear Algebra PACKage (website)

All these libraries (except BLAS and LAPACK that have to be installed on the system) can be downloaded and built thanks to the third-party libraries bundle that we advise to use.

Remark: on Condor supercomputer on which all librairies are already installed, you can skip this section and switch to the next one.

The third-party libraries bundle

We provide a git repository that you can clone (or download). It contains a third-party library installation script and an src directory that contains all the third-party libraries tarballs required by Notus.

To clone the bundle into the notus_third_party directory (no space in the directory path):

git clone https://git.notus-cfd.org/notus/notus_third_party.git notus_third_party

Automatic third-party libraries installation

Default installation

By default the script installs the third-party libraries in the $HOME/usr directory. You can modify the installation directory with the --install-dir option.

To build and install all third-party libraries on different kind of Linux systems, see the Readme page of the script.

Installing all the third party libraries may not be useful since some of them are very specific. We advice to install the minimum required (-m option) first. MUMPS solver may be useful (for 2D problem) and be installed in a second step with options --metis --scalapack --mumps (or scalapack-patched if --scalapack failed).

Script usage

The script build_notus_third_party_lib.sh can be executed with the following options:

Usage : build_notus_third_party_lib.sh [OPTIONS]

  -a                             build and install all third-party libraries
  -m                             build and install minimum required third-party libraries (MXML, ADIOS, HYPRE)
  -c                             clean directories before building
  -j                             number of threads used to compile (default 4)
  -h                             print usage
