The Hewlett-Packard Consortium for Advanced Scientific and Technical (HP-CAST) computing users group works to increase the capabilities of HP solutions for large-scale, scientific and technical computing. HP-CAST provides guidance to HP on the essential development and support issues for such systems. HP-CAST meetings typically include corporate briefings and presentations by HP executives and technical staff (under NDA), and discussions of customer issues related to high-performance technical computing.
