The laboratories of the American society Cray, located in Eagan, Minnesota, have just finished their supercomputers. Cray-YMPS and YMP8I are the names of the new models and are the most powerful of today, with 2,667 million operations per second. The power over large computers so far is not much greater, but they have twice as much memory and work four times faster in peak hours.
For Cray-Research director John Rollwagen, the calculation speed is useless if it does not help scientists solve their problems. Therefore, more than 600 application programs have been carried out for engineering, construction, fluid dynamics, reservoir simulation and oil installations, seismology, basic chemistry, etc.
