<h1>External Packages</h1>
<code>libMesh</code> interfaces to a number of high-quality software packages to provide certain functionality. This page provides a list of packages and a description of their use in the library.
<h2>MPI</h2> The <a href="http://www-unix.mcs.anl.gov/mpi">Message Passing Interface</a> is a standard for parallel programming using the message passing model. PETSc requires MPI for its functionality. <code>libMesh</code> makes use of MPI to when running in parallel for certain operations, including its <code>ParallelMesh</code> distributed-memory, fully unstructured mesh implementation.
<h2>TBB</h2> Since February 2008 <code>libMesh</code> can be configured to use the <a href="http://threadingbuildingblocks.org/">Threading Building Blocks</a> for thread-based parallelism on shared memory machines. Several key algorithms in the library have been refactored to be multithreaded, and this effort will continue as additional profiling reveals additional serial bottlenecks. It is envisioned that for certain classes of problems multilevel parallelism (e.g. message passing between nodes and threading within nodes) will prove more scalable than message passing alone, especially with the introduction of commodity multi-core processors. The reality is that for implicit problems this can only be achieved with a parallel linear algebra library that also uses multilevel parallelism.
<hr>
<h2>PETSc - Parallel Linear & Nonlinear Solvers</h2> The Portable, Extensible Toolkit for Scientific Computation <a href="http://www.mcs.anl.gov/petsc">(PETSc)</a> is a suite of data structures and routines for the scalable (parallel) solution of scientific applications modeled by partial differential equations.
<h3>SLEPc</h3> The Scalable Library for Eigenvalue Computations <a href="http://www.grycap.upv.es/slepc">(SLEPc)</a> is a library for the solution of large scale sparse eigenvalue problems on parallel computers. It is an extension of PETSc and can be used for either standard or generalized eigenproblems, with real or complex arithmetic.

<h1>Supporting libMesh</h2>
If libMesh has been useful in your work please consider supporting its future development.
<br>
<br>
The original development team was heavily influenced by Professor Graham F. Carey, professor of aerospace engineering and engineering mechanics at The University of Texas at Austin, director of the ICES Computational Fluid Dynamics Laboratory, and holder of the Richard B. Curran Chair in Engineering.
<br>
<br>
Many of the technologies employed in libMesh were implemented because Dr. Carey taught them to us, we went back to the lab, and immediately began coding. In a very real way, he was ultimately responsible for this library that we hope you have found useful, despite his continued insistence that "no one ever got a PhD from here for writing a code."
