The TAU performance system is an integrated performance instrumentation, measurement, and analysis toolkit offering support for profiling and tracing modes of measurement. This paper introduces memory introspection capabilities of TAU featured on the Cray XT3 Catamount compute node kernel. TAU supports examining the memory headroom, or the amount of heap memory available, at routine entry, and correlates it to the program's callstack as an atomic event.
