Computer

|
|
|
|
The group
owns a number of computers, including PC Intel Pentium 4, (Stribor), Sun SPARCstation 5 (Oat), Pentium laptop
computer (Shiba), PC Intel Celeron (OatPC), and R. Pratt’s PowerMac G4. |
|
|
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 version of these 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. |
|
|
Help with
all computer connected issues is available from S. Novikov. |
