     "CUBE (CUBE Uniform Behavioral Encoding) is a tool to display a variety
of performance metrics for parallel programs including MPI and OpenMP
applications.  CUBE allows interactive exploration of a multidimensional
performance space in a scalable fashion.  Scalability is achieved in two ways:
hierarchical decomposition of individual dimensions and aggregation across
different dimensions.  All performance metrics are uniformly accommodated in
the same display and thus provide the ability to easily compare the effects of
different kinds of performance behavior.")
