Performance modelling of large-grained parallelism
Technical Report
·
OSTI ID:5791659
Mathematical modelling, computer simulation, and graphical methods are used to analyze the performance of parallel computers. Speedup is used as a performance measure. Large-grained parallel computation is considered, i.e., the case in which multiple tasks each involving substantial computation are executed concurrently. A variable-length task involving the solution of a set of ordinary differential equations is defined and used to validate the performance models that are developed. Experimental results are shown for two machines, a Denelcor HEP with a single process execution module, and an Alliant FX/8. 6 refs., 16 figs.
