Quadrics

QsNet is the main product of Quadrics, a company that initially started in the 1990s as the British firm Meiko that made parallel systems called the Computer Surface 1 and 2. In the CS-2 a very good logarithmic network was included that was made into a separate product after Meiko closed down and the network part was taken over by the the Italian company Alenia and put in the independent company Quadrics. The success came when Digital/Compaq chose QsNet as the network for its large high-performance computer products, the AlphaServer SC line. Some very large configurations of these machines were sold, e.g., at the Pittsburgh Supercomputing Centre and the French CAE. QsNet proved to be a very fast and reliable network and since about three years QsNet is also offered for cluster systems. more...
