Gridwars (aka GRID WARS) was a programming contest announced in November 2002 by Engineered Intelligence (EI). The competition was devised to promote EI's product called CxC (a parallel programming language) introduced the same day. Gridwars was also announced in selected forums and through personal invitations.
Four contests were held in total: in February 2003, in June 2003 (Gridwars II), in November 2003 (Gridwars Interactive), and in April 2004 (Gridwars III).
EI was founded by Matt Oberdorfer; in the late 2005 EI discontinued CxC and announced a new product called "I/O accelerator". In the early 2006 EI changed name to Gear6 and replaced Gridwars front page with the announcement of discontinuation. Shortly after the web site www.gridwars.com was shut down.
