With petascale computing just over the horizon, the super-computing community is becoming increasingly focused on developing strategies to take advantage of this new level of computing power. Petascale computing will eventually impact all scientific and engineering applications, but to reach its full potential, the problems of both hardware and software must be addressed. IBM's Blue Gene/P, the second generation of the Blue Gene supercomputer is designed with a Universal Performance Counter (UPC) Unit at each node capable of monitoring 256 events concurrently, unlike many microprocessors that provide only a few performance counters.
