Our Mission
High-performance computing
The Research Computing Group at the CUNY Graduate Center implements and supports Open Source Linux research computing facilities at the CUNY Graduate Center, and provides assistance with research computing to research groups within The City University of New York (http://www.cuny.edu). For our purposes, research computing includes high-performance computational clusters and related technology; recently research computing has taken on web-enabled statistical computation and open source journal projects for the social sciences. Research Computing operates under the aegis of the Office of the Vice President for Information Technology and External Programs (http://web.gc.cuny.edu/provost/apit/index.html) at the CUNY Graduate Center (http://www.gc.cuny.edu).
Computer Science Lab
In Fall 2006, Research Computing assumed operational responsibility for the Graduate Center's computer science lab.
Open Source
Our philosophy is to use Open Source software wherever possible; see Why Open Source Software? Look at the Numbers! (http://www.dwheeler.com/oss_fs_why.html) and How to Evaluate Open Source Software (http://www.dwheeler.com/oss_fs_eval.html) by David A. Wheeler. Research Computing LAMP (http://www.onlamp.com) projects continue to demonstrate the cost-effectiveness of running LINUX/Apache/MySQL/PHP web servers. The initial LAMP web sites were developed in April 2005 for the for the social sciences.
Strategic Defenestration Initiative
According to www.dictionary.com (http://dictionary.reference.com/search?q=defenestration), one of the meanings of the word defenestration is "... 5. The act of completely removing Micro$oft Windows from a PC in favor of a better OS (typically Linux)."
The Research Computing Strategic Defenestration Initiative seeks to replace expensive, proprietary Windows services with suitable robust, sophisticated, maintainable and cost-effective open source Linux (http://www.linux.org) alternatives. In general, Research Computing attempts to use Open Source software systems wherever possible; see Why Open Source Software? Look at the Numbers! (http://www.dwheeler.com/oss_fs_why.html) and How to Evaluate Open Source Software (http://www.dwheeler.com/oss_fs_eval.html) by David A. Wheeler. Also, see The Practical Managers Guide to Open Source (http://windows-linux.com/practicalOpenSource/) by Maria Winslow.
NYT Article: Corrupted PC's Find New Home in the Dumpster (http://www.nytimes.com/2005/07/17/technology/17spy.html?pagewanted=1&ei=5094&en=178b2edcf06c6a45&hp&ex=1121572800&partner=homepage) Windows PC owners, including some Ph.D.s in computer science, are throwing out their virus and adware infected PCs, instead of cleaning them up! This kind of behavior would be considered irrational among Linux users; among Windows PC users, trashing an infected PC is considered "rational." All the more reason to switch to Linux: Linux PC's are considerably less succeptible to viruses and adware, which are mostly targeted for the Windows operating system.
LAMP versus WIMP Some resources on the Linux Apache MySQL PHP stack, versus the Windows IIS MSSQL asP stack.
This editorial (http://linux.sys-con.com/read/84967.htm) in LinuxWorld (http://linux.sys-con.com/) discusses how LAMP and open source technology enabled Google (http://www.google.com) and Amazon.com (http://www.amazon.com) to grow "...quickly into industry leaders...LAMP technologies are a great equalizer that can allow a relatively small vendor...to build a world class Web site and compete next to a Fortune 1000 company." While success has given Amazon and Google the means replace their open source Linux and Apache infrastructure with proprietary software systems, they have not done so.
