Synopsis:
OIT 64-bit Computing Service: Answers to Frequently Asked Questions (FAQ)

Solution:
To accommodate the needs of those members of the Princeton community who run computationally intensive jobs using commercial software like Matlab, SAS, and Mathematica, open source software, or home grown applications, OIT provides a 64-bit computing service on both a Sun Solaris platform and a Linux platform. A Sun Solaris server called Tombstone, and Redhat Enterprise Linux servers called Sixtyfour and Lxiv are in place to provide registered 64-bit services for computationally intensive uses.

If you would like to use licensed scientific, math, or engineering software and running computationally intensive work on the Arizonas, you should register for the 64-bit computing servers, Tombstone, Sixtyfour, and Lxiv to use the software on those servers. The registration web page www.princeton.edu/register64 requires only a University netID and password. Registration takes effect within 30 minutes. The list of software provided can be found at: OIT Unix server specifications and licensed software locations.

All licensed software is available on Tombstone; Sixtyfour and Lxiv provide access to a subset of licensed software. If a registered user does not log in to the service for a consecutive period of 5 months, mail will be sent warning the user of registration expiration in a month unless the user logs in again within a month.

Because it is intended for computationally intensive work, the 64-bit service does not provide e-mail client software such as Pine, and it does not have access to the /usr/campuscgi file system. The old open source software file system /usr/princeton will no longer be available.

The new open source file system /usr/psr will be available on the new Arizonas as well as on Tombstone, Sixtyfour, and and Lxiv. Commercially licensed software will also be available on Tombstone, Sixtyfour, and and Lxiv in the /usr/licensed file system. Additional packages may be added through sponsorship by an individual or department. See the PSR Public Software page for more information.

For historical reference:
As of January 30, 2006, Dell servers running Redhat Enterprise Linux replaced the current Arizona servers. The Arizona servers can still be used to read e-mail with Pine, edit files with vi, and publish web pages, and will continue to use the Arizona name. There is no scientific, math, or engineering software on the Arizonas, and cpu usage of individual processes is limited. To see what is different on the new Arizonas, see OIT Unix server specifications and licensed software locations.
