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 |
|
|
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. |
