PerfSuite is no longer supported on Blue Waters.

PerfSuite was an easy-to-use collection of tools and libraries to support application software performance analysis on Linux-based systems (x86, x86-64, ia64, ppc64 and ppc32). It included components to assist with performance measurement tasks, such as hardware performance counting and profiling, and itimer profiling. PerfSuite was developed by Rick Kufrin and subsequently supported by Rui Lui of NCSA.
