17 Aachen on Rank 180 in e Over 2 TeraFlop/s Linpack Permance April The upgrade from UltraSPAR III to UltraSPAR IV including an increase of the main memory capacity more than doubled our Linpack permance! A linear system with 499,200 unknowns was solved in 11:12:48.8 hours at an average speed of billion floating point operations per second (GFlop/s). The program had a total memory footprint of 2 Terabyte processor cores were kept busy with 82,930,000,000 million floating point operations. 17 RZ.RWTH-AAHEN.DE enter omputing and ommunication
