  abstract= "This work considers the pros and cons of different size SMPs
     as nodes in clusters. We investigate the Intel SMP
     architecture and consider the potential of and some problems
     with larger node-sizes in clusters of multiprocessors. Six
     applications that represent different classes of parallel
     applications are developed in versions that support both
     shared and distributed memory. Performance measurements are
     done on three different clusters of multiprocessors, with
     the purpose of identifying how the number of processors in
     each SMP node impacts the cluster performance. Our results
     show that clusters using higher order SMPs do not give a
     clear performance benefit compared to clusters using two-way
     SMPs. Off the bench mark-suite of six applications, the
     performance of two turn out to be independent of node-size,
     two show an advantage of larger node-sizes, as much as 34
     percent improvement of eight-way nodes over a dual-system,
     while the remaining two show an advantage of dual-processor
     nodes as big as 11 percent over an eight-way cluster."
