Abstract
The author describes experiences over the past year with the Intel iPSC/860, a distributed memory MIMD parallel computer based on the Intel i860 floating point processor. Attention is given to the system at NASA Ames Research Center, which has 128 node and a theoretical peak performance of over 7 GFLOPS. System stability, computer performance measured by the NAS (Numerical Aerodynamic Simulation) kernels, and results from a two-dimensional computational fluid dynamics application are discussed.<>
