Abstract
This thesis contains a detailed comparison of the computation and communication performance of two commercially-available hypercube multiprocessors, the Intel iPSC and Intel iPSC/2. In a previous performance study [7], some of the benchmarks where also run on an Ncube/four hypercube; where appropriate, the results of these tests are also included.
Three kinds of benchmarks were used. The processor benchmarks measure computation performance. Many of these benchmarks are well-known programs used to measure traditional uniprocessor computers [15, 29]. Because computation performance is a function of compiler as well as processor, both C and FORTRAN benchmarks are included. In addition to comparing processor/ compiler performance across machines, the relative performance of the C and FORTRAN compilers for each machine is examined
The second class of benchmarks, the communication benchmarks, measures conununication performance. The communication benchmarks consist of simple conununication benchmarks, which measure link level (i.e. point-to-point) communication characteristics, and synthetic communication benchmarks, which measure the performance of the entire communication network under parametrically-generated communication loads.
Both the processor and communication benchmark set are based on the work of Grunwald and Reed [16]. The third set of benchmarks is a set of application programs that depend on both the computation and communication performance of the hypercubes.
