==Application Details==
*Description: a software library of high performance preconditioners and solvers for the solution of large, sparse linear systems of equations on massively parallel computers
*Version: 2.11.0 (compiled with intel)
*Module: hypre/intel/2.11.0 and hypre/intel/2.11.0b
*Licence: GNU

==Usage Examples==

'''hypre''', a software library of high performance pre conditioners and solvers for the solution of large, sparse linear systems of equations on massively parallel computers. The
hypre library was created with the primary goal of providing users with advanced parallel pre conditioners. The library features parallel multi-grid solvers for both structured and unstructured grid problems. For ease of use, these solvers are accessed from the application code via hypre’s conceptual linear system interfaces, which allow a variety of natural problem descriptions.

[username@login01 ~]$ module add hypre/intel/2.11.0
</pre>

===Compilation===

''hypre'' is a library s it, or it could be required at compilation time also.

A typical C++ code snippet requiring '''hypre''' (source Github) is shown below:

<pre style="background-color: #f5f5dc; color: black; font-family: monospace, sans-serif;">

Description: This code solves a system corresponding to a discretization
of the Laplace equation -Delta u = 1 with zero boundary
conditions on the unit square. The domain is split into
a n x n grid of quadrilateral elements and each processors
owns a horizontal strip of size m x n, where m = n/nprocs. We
use bilinear finite element discretization, so there are
nodes (vertices) that are shared between neighbouring
processors. The Finite Element Interface is used to assemble
the matrix and solve the problem. Nine different solvers are
available.
