Carol Petersen Muser is a Senior Software Design Engineer on the HP-UX Kernel Performance Team. Her area of expertise includes kernel tracing, profiling and instrumentation, benchmark tracking, and troubleshooting. Her depth in this role spans a decade.
Through Carol’s dedication to exceptional performance, ktracer is faster by an order of magnitude. Through her attention to a richer total customer experience, ktracer is easier to invoke and understand, and more broadly available.
Because of her innovativeness and technical ability, ktracer is capable of creating thousands more trace points, dynamically programmable action at each trace point, and playing well with Itanium and PA/RISC processors, Cell OL*, cell local memory (CLM) and soon, dynamic loadable kernel modules and HP Virtual Machines.
