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