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 many books available on various operating systems, languages and software, which are kept in 325 OEH (also 327 OEH and 222 Allen). This is also the place to look for hardcopy documentation on the codes.
