Chuck 11:38, 26 September 2007 (EDT) The wiki was such a hit in the Division that the word got out to the rest of the department and people in other divisions wanted to use the wiki. With the permission of the Department Director, access to the wiki was expanded to allow each of the divisions to have their own space, and the wiki was subsequently renamed the Integrated Computation and Communications Division wiki (ICCD). Also, it was desireable for some of the persons accessing the wiki be able to do so from off site. There are specific security requirements for this, notably that access must be controlled through the same two-factor authentication method used to access secure web pages at the lab, and that external access be limited to people logging in through our VPN. This required some hammering, filing, and shaping of the Apache/PAM security stack, and tweaking of the Apache and wiki configuration files. This was done, and there was much rejoicing!!

Description
This was the wiki for the High Speed Systems Division of the Integrated Computation and Communications Department of the Computation Directorate at Lawrence Livermore National Laboratory. It is now the wiki for the department. The purpose of the wiki is to capture the corporate knowledge of the division in a peer-editiable serchable form in an attmpt to document the rapidly changing computational environment, where systems are installed, brought to General Availability, age, and are replaced over the span of only a few years. Many of the systems here in the Division are current top 10 machines in the Top 500 Supercomputers list, with BlueGene/L in the number 1 position and ASC Purple in the number 4 position, and 8 other systems at various positions.

The wiki was launched originally on March 9, 2006 as a pilot project and then migrated to it's current home, a 1U Supermicro dual dual-core 3.06GHz Xeon CPU with 4gb DDR2 memory and dual-redundant hot-swappable 72gb HDD, beginning on June 14, 2006 and completed on July 10, 2006. The server was subsequently renamed 'gasta' which is Irish for 'quick'.
