Abstract
In a joint project between the Swedish Institute of Applied Mathematics, ABB Corporate Research, SAAB Military Aircraft, and Volvo Flygmotor the possibility of running industrial production codes in parallel on workstation clusters is studied. In this paper we report on the experiences with two such codes.
A production code for numerical solution of the stationary Euler and Navier-Stokes equations for compressible flow in three space dimensions, accelerated by a multigrid method, is modified to run on a cluster of workstations at SAAB Military Aircraft. A 3-D Navier-Stokes code with combustion is parallelized and numerical simulations of the turbulent flow in two combustion chambers are performed on a cluster of workstations at Volvo Flygmotor.
The parallelization is done using the message passing system PVM and the workstations used for the tests are interconnected with Ethernet.
When the SAAB code is run on a single grid we reach 0.64 of the speed of one CRAY Y-MP processor by using eigth SGI R4000 workstations. At Volvo Flygmotor, speedup factors 2.5 and 9.7, as compared to the one processor case, are obtained for moderate size problems run on networks of three HP 9000-735 and twelve SGI R4000, respectively.
