How To Install scotch on Debian 12
Introduction
In this tutorial we learn how to install scotch on Debian 12.
What is scotch
scotch is:
Its purpose is to apply graph theory, with a divide and conquer approach, to scientific computing problems such as graph and mesh partitioning, static mapping, and sparse matrix ordering, in application domains ranging from structural mechanics to operating systems or bio-chemistry.
The SCOTCH distribution is a set of programs and libraries which implement the static mapping and sparse matrix reordering algorithms developed within the SCOTCH project.
SCOTCH has many interesting features:
o Its capabilities can be used through a set of stand-alone programs as well as through the libSCOTCH library, which offers both C and Fortran interfaces.
o It provides algorithms to partition graph structures, as well as mesh structures defined as node-element bipartite graphs and which can also represent hypergraphs.
o It can map any weighted source graph onto any weighted target graph. The source and target graphs may have any topology, and their vertices and edges may be weighted. Moreover, both source and target graphs may be disconnected. This feature allows for the mapping of programs onto disconnected subparts of a parallel architecture made up of heterogeneous processors and communication links.
o It computes amalgamated block orderings of sparse matrices, for efficient solving using BLAS routines.
o Its running time is linear in the number of edges of the source graph, and logarithmic in the number of vertices of the target graph for mapping computations.
o It can handle indifferently graph and mesh data structures created within C or Fortran programs, with array indices starting from 0 or 1.
o It offers extended support for adaptive graphs and meshes through the handling of disjoint edge arrays.
o It is dynamically parametrizable thanks to strategy strings that are interpreted at run-time.
o It uses system memory efficiently, to process large graphs and meshes without incurring out-of-memory faults;
o It is highly modular and documented. Since it has been released under the CeCILL-C free/libre software license, it can be used as a testbed for the easy and quick development and testing of new partitioning and ordering methods.
o It can be easily interfaced to other programs. The programs comprising the SCOTCH project have been designed to run in command-line mode without any interactive prompting, so that they can be called easily from other programs by means of system() or popen() calls, or piped together on a single command line. Moreover, vertex labeling capabilities allow for easy renumbering of vertices.
o It provides many tools to build, check, and display graphs, meshes and matrix patterns.
o It is written in C and uses the POSIX interface, which makes it highly portable. PT-SCOTCH uses the MPI interface, and optionally the POSIX threads.
There are three methods to install scotch on Debian 12. We can use apt-get, apt and aptitude. In the following sections we will describe each method. You can choose one of them.
Install scotch Using apt-get
Update apt database with apt-get using the following command.
sudo apt-get update
After updating apt database, We can install scotch using apt-get by running the following command:
sudo apt-get -y install scotch
Install scotch Using apt
Update apt database with apt using the following command.
sudo apt update
After updating apt database, We can install scotch using apt by running the following command:
sudo apt -y install scotch
Install scotch Using aptitude
If you want to follow this method, you might need to install aptitude first since aptitude is usually not installed by default on Debian. Update apt database with aptitude using the following command.
sudo aptitude update
After updating apt database, We can install scotch using aptitude by running the following command:
sudo aptitude -y install scotch
How To Uninstall scotch on Debian 12
To uninstall only the scotch package we can use the following command:
sudo apt-get remove scotch
Uninstall scotch And Its Dependencies
To uninstall scotch and its dependencies that are no longer needed by Debian 12, we can use the command below:
sudo apt-get -y autoremove scotch
Remove scotch Configurations and Data
To remove scotch configuration and data from Debian 12 we can use the following command:
sudo apt-get -y purge scotch
Remove scotch configuration, data, and all of its dependencies
We can use the following command to remove scotch configurations, data and all of its dependencies, we can use the following command:
sudo apt-get -y autoremove --purge scotch
Dependencies
scotch have the following dependencies:
