The basic goal of the effort summarized here is to greatly increase the amount of effective computing available to the average CDF member and for special projects while maintaining an environment that is easy to use for the average physicist. Where possible, familiar tools and interfaces are used while trying to extend their applicability to a global computing environment.
At present, we have achieved a uniform job submission environment to a set of resources that increases the total cpu available over the central systems by approximately 1.8 THz on a guaranteed basis. Over the next few months to a year, we expect to expand this base and to target the availability of additional resources that do not use the "classic CAF" paradigm by moving into a more general grid environment. We will also switch the base operating systems and software to more modern versions in an effort to stay in synch with (and also lead) other developments in the field. During this process, we expect to maintain our present concentration on ease of use for the physicist.
The number of active remote facilities open to general CDF use has expanded considerably since the inception of this project in January 2004. In addition, other facilities are on the horizon. If you want to join or add resources to this effort, send e-mail to Igor Sfiligoi and/or Ian Fisk, or more generally to CDF-DCAF-Admin at fnal.gov.
The next CDF Grid workshop will be held March 10-11, 2005 in room FCC1 in the Feynman Center at Fermilab. All collaborators interested in grid computing are invited. Our most recent previous workshop was held Sept. 9-10, 2004. The resulting WebTalks pages are available to CDF members for the first, second, and third sessions and the full agenda is also publicly available in plain text form.
[*] Total resources at each cluster are only listed for those portions dedicated to CDF on a guaranteed average basis, and open to all CDF users. In many cases, especially for the larger offsite clusters, more capacity is available and can be scheduled for special needs. Contact the site administrator at each site above if you have questions or would like to pursue a special project.

|The above links are current as of the most recent workshop, Sep. 9-10, 2004 at Fermilab. Previous workshops have been held Apr. 1-2, 2004 at Fermilab and Jan. 20-22, 2004 at the University of Florida. (The original documentation from the Florida workshop has largely been kept up to date rather than replaced, so these links still provide a valuable reference.)|
