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. |
