<H2>HPL Documentation</H2>

The  HPL software distribution comes  with a set of text files explaining
how to install,  run and tune the software. These files reside in the top
level  directory  and their names are in upper case.  To  a large extent,
this page reproduces them. In addition,  man- and HTML-pages are provided
for every routine in the package. To access the man pages,  one  must add
hpl/man  to its  MANPATH  environment variable.  The  HTML  pages  can be 
accessed on this site,  or by pointing your browser to your local hpl/www
directory. Finally,  the source code has been heavily documented. Despite
all the other documentation efforts, the  source  code remains  the  most
trustworthy  and truthful piece of information about what goes on in HPL.

<STRONG>Grid Management</STRONG>  Most of these routines have a direct
MPI equivalent.  On new systems,  when the entire MPI functionality is
not yet readily available, these functions are particularly convenient
since they rely on a mininal  subset of the MPI standard.
