Computer facilities |
|
|
|
|
|
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. |
