Stardent Computer Corp, Newton, Massachusetts has signed up its rival in the minisupercomputer stakes, Richardson, Texas-based Convex Computer Corp as the second licensee for its Application Visualisation System software, following a similar deal with DEC back in March. The Application Visualisation System software, which originated with the Stellar Computer Corp side of the merged graphics supercomputer business, will enable Convex to target more aggressively market areas such as the petroleum, computational chemistry, government and aerospace, and appliactions in computer-aided engineering. It particularly hopes that the software will help it to win business where customers are looking to integrate Convex supercomputers as servers for use with their graphics workstations.
