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.
