Driven by growing application requirements and accelerated by current trends in microprocessor design, the number of processor cores on modern supercomputers is increasing from generation to generation. However, load or communication imbalance prevents many codes from taking advantage of the available parallelism, as delays of single processes may spread(More)
Programming and optimising large parallel applications for multi-core systems is an ambitious and time consuming challenge. Therefore, a number of software tools have been developed in the past to assist the programmer in optimising their codes. Scalasca and Vampir are two of these performance-analysis tools that are already well established and recognised(More)
