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. |
