The parallel performance on three
different multiprocessor platforms of the ZEUS-3D Blast test problem using
the MoC algorithm is shown below. The long listings give more extensive
information.
- CODE: ZEUS-3D version 3.4.1.
- PROBLEM: Blast -- the expansion of a hot sphere of plasma into
an initially uniform magnetic medium.
- GEOMETRY: Cartesian XYZ
- GRID: 128 X 64 X 64 zones. The ratio of neighboring zone dimensions
is 1.02. The smallest zones are near origin.
- ALGORITHM: van Leer advection, Method of Characteristics scheme
to evolve magnetic fields
- PRECISION: DOUBLE
- DATA: In the graph below, the number of Megaflops for a given
physical problem is determined by comparing the number of CPU seconds
used by the master thread in computing the evolution (some system and
ZEUS-3D overhead is excluded). The data are scaled to the results from
running on one Cray C90 processor, which has a hardware performance
monitor capable of counting MFLOPS.
