The current trend in workstation architectures toward several very fast scalar processors running in parallel and sharing the same physical memory space provides a very, good computational architecture for high-performance visualization.
In ORNL's case, the QMC/DCA code (specifically, an individual Markov chain in the Monte Carlo simulation) does not scale well on scalar processors, and the algorithm the team was using became too computationally inefficient when expanded beyond four-site clusters.
At the end of the day, the conventional scalar processors used in most HPC systems are fundamentally limited in their ability to extract more parallelism from application codes.
Fujitsu's supercomputer provides two, 2.5Gflop vector units shared by four scalar processors. Every fouror five years the number of processors is doubled, providing a gain of 18% per year.
