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. |
