<TT>Mpich</TT> is a freely available implementation of the MPI standard that runs on  
a wide variety of systems.    
The details of the <TT>mpich</TT> implementation are described in  
[<a href="node66.htm#-Bib7">7</a>]; related papers include  
[<a href="node66.htm#-Bib5">5</a>] and [<a href="node66.htm#-Bib6">6</a>].
