%X 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.
