The International Supercomputing Conference 2007, the major European HPC conference and the announcement location for the June Top500 lists, has issued a call for abstracts for research posters and Birds of a Feather sessions. The deadline for submitting abstracts is Thursday, April 12.
The conference is June 26-29 in Dresden, Germany.
(Something I didn’t know: ISC actually predates SC’xy by two years. The first ISC was held in 1986, while SC didn’t get started until 1988.)
