The end of the ’90s was tough few years for supercomputers. These articles describe the spat that broke out between Cray and NEC a Japanese firms that was accused of selling supercomputers at less than cost price. After the spat was settled Cray entered an agreement to resell NEC supers SX-5 & SX-6 into the …
The National Centre for Atmospheric Research NCAR/UCAR in Colorado has a long association with Cray supercomputers. Starting in 1977 with the Cray-1 SN3 the site invested in some the best supercomputers available. More recently a Cray Petaflop class machines will be used to explore climate research. In 2021 the site awaits the commissioning of Derecho …
