ab initio programs
Sometime ago I sent to the comp. chem. list a summary about the GAMESS-UK
program. It looks that there are some corrections If you are still keeping
the old GAMESS-UK summary mail, please through it away and use this one. I am
compiling these data since I think they are important for a few of us who are
thinking to purchase an ab initio program.
This is a summary of the informations I got about GAMESS-USA, GAMESS-UK
and CADPAC ab initio programs. Please notice that the price of these programs
are for academic only.

GAMESS-UK is an ab initio molecular electronic structure program for
performing SCF- and MCSCF-gradient calculations, together with a variety
of techniques for post Hartree Fock calculations.
Based on the original GAMESS software
from the National Resource for Computational Chemistry (NRCC, 1981),
development of the code over the past decade has been coordinated
by the Science and Engineering Research Council (SERC) Daresbury Laboratory,
and carried out by an International Consortium comprising Dr. M.F. Guest
(SERC Daresbury Lab., UK), Dr J.H. van Lenthe (Utrecht University,
The Netherlands), Dr. J. Kendrick (ICI plc Ltd, Wilton, UK)
and Dr. K. Schoffel (Norsk Hydro, Norway).
Recognising the increasing effort required in the support of
large scale computational chemistry codes, SERC has granted the above
consortium, through Computing for Science Ltd, an exclusive licence
to market the code and related products, with a view
to generating income to be dedicated to the upkeep, development and
maintenance of the software.
GAMESS--UK is currently available on a wide range of supercomputers,
superminis and workstations. Recent implementations
include those on the Cray Y-MP, Convex C3800 and C220,
Hewlett Packard 9000 Series Model 7xx, IBM RS6000-based models,
DEC (DEC Station 5000 series and Alpha AXP family),
Silicon Graphics (Challenge and Indigo family) and Sun (SparcStation 10).
Parallel versions are available for the Intel iPSC/860,
both transputer and i860-based Meiko Computing Surfaces, and
workstation clusters (both homogeneous and heterogeneous) from
Hewlett Packard and IBM.
GAMESS-UK may be used for a variety of types of investigations
1. Theoretical studies of reaction surfaces; SCF, MCSCF and
correlated second-order Moller Plesset (MP2) calculations of equilibrium
and transition structure geometries, and the evaluation of
force constants and vibrational frequencies at these stationary points.
2. Energy assignments in the entire field of electronic
spectroscopy; calculation of IR and Raman intensities, together with the
spectroscopic properties of highly excited molecular
and ionic states; evaluation of transition moments.
3. Graphical and numerical analysis of
Hartree-Fock and correlated wavefunctions.
4. Generation of zero-order wavefunctions required in the more
extensive treatments of dynamical correlation energy.
Applicability to general systems with many electrons in this
treatment of dynamical correlation energy.
Benchmark treatments of correlation energy using Full-CI calculations.
5. Theoretical mechanistic studies of chemisorption in heterogeneous
6. Reaction field studies of solvation effects.
7. Treatment of bio--organic and related molecules
through Direct-SCF and Direct-MP2 calculations and electrostatic potential
Version 1.0 of the code is now available as a series of modules,
GAMESS-1 - GAMESS-9). A summary of the features of each module is
