Computer
facilities |
|
|
|
|
|
The
group owns a number of computers, including PC Intel Pentium 4, (Stribor),
Pentium laptop computer (Shiba), PC Intel Celeron (OatPC). |
|
|
Stribor
(operated by Linux Red Hat 9) serves as the main group computer. All user files are stored on Stribor. It has the latest version of Intel fortran
compiler, and users are encouraged to compile, debug and run their codes
using Stribor. |
|
|
Stribor
also runs the IMAP mail server and Apache web server. The group’s website
address is http://stribor.phyast.pitt.edu |
|
|
Old
large codes (Rayleigh and Compton scattering, bremsstrahlung) can be run on
Oat (operated by Solaris 2.6). Rayleigh & Compton have also been modified
for compilation under the Windows operating system. The latest versions can be obtained from L.
LaJohn. |
|
|
OatPC
runs WindowsXP and has all commonly used applications. Short term visitors who prefer Windows over
Linux can use OatPC. |
|
|
The
group has books available on various operating systems, languages and
software, also hardcopy documentation on the codes. |
