Parallel processing specialist Alliant Computer Systems is the latest company to sign up with Verdix Corp, Chantilly, Virginia, for a source technology licence agreement for the Verdix Ada Development Systems software, allowing Alliant to adapt the VADS to run on its high-performance vector and parallel processing FX/Series family of computer systems. Ada provides for concurrent execution of multiple program tasks, making it an appropriate language for the Alliant FX line. In adapting VADS, Alliant will support full parallel execution of Ada programs, resulting in significantly faster processing speed. Alliant hopes that the addition of Ada will enable it to extend the application of transparent, scalable parallel and vector processing to new and rapidly growing markets for mini-supercomputers. For Verdix, the agreement is the twentieth source licence it has sold to US companies; 17 of these licences are in the hands of computer manufacturers – and Alliant is the third mini-supercomputer manufacturer to sign with Verdix in the past quarter.
