Code Library

The computers primarily available for use are the group's own Sun UNIX workstations. There is also the VAX system operated by the Computing and Information Systems (CIS) department, but this system tends to have older versions of the codes, and new users will find more help available if they are using the workstations.

In order to run the codes on local systems, look for executables in the directories:

UNIX workstations: /usr/local/atomic/bin

VAX system: USR2:[10104.ATOMIC1.EXE]

We encourage use of the SLATEC numerical library, which contains a wide variety of numerical algorithms written in FORTRAN. Source code is available in the directories:

UNIX workstations: /usr/local/atomic/slatec

VAX system: USR3:[PHY.SLATEC]

More information is available on the group's web site at:

http://stribor.phyast.pitt.edu/

The group has books available on various operating systems, languages and software, also hardcopy documentation on the codes.
