<H1>PeIGS -- Parallel Eigensystem Solver </H1>
|
|
|
|
PeIGS is a scalable, fully parallel, implementation of a
|
|
generalized and standard real, symmetric, dense eigensystem
|
|
solver callable from both Fortran 77 and C.
|
|
|
|
Only double precision is currently supported.
|
|
|
|
<P>
|
|
PeIGS runs on a variety of parallel computer systems, including
|
|
networks of workstations, and can easily be ported to any machine
|
|
that supports the message passing programming model.
|
|
|
|
The current version of PeIGS utilizes the
|
|
<A href="/docs/global/tcgmsg.html"> TCGMSG </A>
|
|
portable
|
|
communication package, MPI, or Intel NX intrinsics.
|
|
|
|
<P>
|
|
PeIGS is being used at the
|
|
<A HREF="/docs/pnl.overview.html">
|
|
Pacific Northwest Laboratory (PNL) </A>
|
|
as a production-grade library package for the construction of scalable
|
|
<A HREF="/"> quantum
|
|
chemistry application programs</A>,
|
|
including parallel SCF, MCSCF, DFT, and MP2 methods. Due to the
|
|
speed and scalability of PeIGS, the time for the eigensystem solution
|
|
has been reduced to an insignificant fraction of the total
|
|
time-to-solution for these applications.
