- PROBLEM: Blast -- the expansion of a hot sphere of plasma into
an initially uniform medium (Sedov-Taylor Blast Wave).
- GEOMETRY: Cartesian XYZ
- GRID: The physical grid is uniform and partitioned into 3-D
"tiles" with 32 x 32 x 32 zones. Each process is assigned to 1 tile.
Thus, we scale the total amount of work to be done to match the number
of processes. This is conceptually different from some other LCA benchmarks,
and direct comparison with them is not straigtforward.
- ALGORITHM: MPI used to pass messages; communication overlapped
with computation; van Leer advection
- PRECISION: Single precision on Crays (64-bits), DOUBLE PRECISION
on others.
- DATA: In the tables, "tused" is the average CPU seconds used
by each process in computing the evolution (some system and ZEUS-MP
overhead is excluded). The Zone-Cycles/sec is the total number of mesh
zones times the number of time steps divided by tused.
