Outreach, Community Building, and Professional Service

CSCAPES is in a sense an outgrowth of the broader effort of building a community around the field of Combinatorial Scientific Computing. The SIAM Workshop on CSC is the premier international event for the field. Since the Workshop's inception in 2004, four meetings have been organized, the latest in October 2009 in Monterey, CA. In addition, CSC minisymposia are regularly organized at SIAM and other Conferences, and CSCAPES has been organizing more SciDAC-oriented outreach activities. This page chronicles some of the major CSC events that have ocurred over the last few years and in which CSCAPES members were involved as co-organizers or in other capacities. The page also lists various professional services CSCAPES members are currently providing to the computing community at large.
