Synopsis:
Detailed information regarding the implementation and rollout schedule of 64-bit Unix public computing environment.

Solution:
OIT has been upgrading and improving the public Unix computing environment since September of '04. The following itemizes the rollout of the project for historical reference (with most recent upgrades listed first).

January 30, 2006
The current Arizona servers were replaced by Dell servers running Redhat Enterprise Linux. Those who log in to the Arizona servers to read e-mail with Pine, edit files with vi, and publish web pages continue to do so on these new Linux servers, which continue to use the Arizona name. There is no scientific, math, or engineering software, and cpu usage of individual processes is limited on the new Arizonas (see www.princeton.edu/register64 to run computationally intensive software). To read e-mail with Pine or do file editing, continue to use the Arizonas as you have always done. If you made modifications to your environment on the old Arizonas, you may notice some changes on the new servers. For detailed information regarding what is different on the new Arizonas, please see: OIT Unix server specifications and licensed software locations.

January 24, 2005
New 64-bit Redhat Enterprise Linux server called sixtyfour becomes available. This server joins the Sun Solaris server tombstone in providing service for those who run computationally intensive jobs using commercial software like Matlab, SAS, and Mathematica, open source software, or home-grown applications. Like tombstone, sixtyfour is a registered service dedicated to computationally intensive work. It does not provide e-mail client software and does not have access to the /usr/campuscgi file system. The arizona and hats servers continue to be available for general purpose work. (Details....)

September 1, 2004
Three statistical packages, SAS, Stata, and DBMS/Copy, move from the Arizona servers to the new 64-bit computing server, tombstone. The 64-bit computationally intensive environment is a registered service, so to have access to these packages, users need to register online (you will be prompted for your University netID and LDAP password).

September 1, 2004
Default versions of software available on OIT's servers and via the Princeton Software Repository are updated. Wherever possible, the previous version of the software is left available for those who may need them. Four facilities change default on September 1:

• SAS Unix - the version available on tombstone will be 9.12 (it was 8.20 on the arizonas before the license was moved to tombstone). The new license does not support backward compatibility, so SAS 9.12 will be the only version available on tombstone. Those who have used SAS in the past 6 months will be notified by e-mail.
• Matlab on the hats, arizonas, and tombstone - The new default version will be 7.0.14. The previous version, 6.5.13 is still available as well as a number of more historical versions. The matlab wrapper reports the default version and the available older versions.
• Maple on the hats, arizonas, and tombstone - The new default version will be 9.5. The previous version, 9 is still available as well as a number of more historical versions. The maple wrapper reports the default version and the available older versions.
• PSR - The "current" version of PSR will be upgraded from OpenPKG 1.x to OpenPKG 2.1 on both the NFS filesystem and RPM repository. Users who have installed the RPM's locally on their systems will need to perform the RPM upgrade if the want the newer packages. All affected registered users of PSR will be notified via e-mail of the change. The older OpenPKG 1.x packages will continue to be available as the "previous" version.
