Parallel Code Performance of University of Utah Large-Eddy Simulation Model on seaborg (IBM SP2)

The following four plots are based on runs performed on various numbers of processors, using 64 x 64 x 110 grid points.
They show how the following quantities scale with the number of processors.

MFLOP/s (linear scale)

MFLOPS/s (log scale)

The following two plots also include results from a model of code performance.

execution times of load/store and communication instructions relative to computing instructions

fractional times of load/store, computing, and communication instructions
