In the proceedings of CUG2006 we published a paper evaluating the performance of the HPCC benchmark suite on the Cray XT3, jaguar, and newly-upgraded Cray X1E, phoenix supercomputers at the Center for Computation Sciences (CCS) at Oak Ridge National Laboratory (ORNL). Although phoenix has remained unchanged since this paper was published, jaguar has undergone significant changes. It has been upgraded from a single-core XT3 system to a combined dual-core XT3 and XT4 system. This paper revisits HPCC on jaguar and discusses the effect that the past year's system upgrades have had on overall performance.
