Taylor Test - Benchmark Problem
I have
run this DYNA2D simulation since LLNL received its
first CRAY in 1978.
This “Taylor” test simulation is of a cylindrical copper projectile impacting a
rigid boundary at 190 m/s.
The initial simulations (prior to the Pentium III)
were run to 70 micro-sec in 3519 cycles.
With the release of the Pentium III, the simulations were run to 500
micro-seconds (29658 cycles) to accommodate the faster computers.
1. “CPU time to 70 msec” is the processor time for the benchmark, 500
element,
2. “CPU time 500 msec” is the same problem run to 500 msec (29658 cycles).
This is a better benchmark for faster computers because the CPU time with the
faster computers is dominated by startup, ending and I/O.
3. TPEC is "time per zone cycle" (CPU time
/ # of elements / problem cycles).
4. The Cray 1 ratio is the ratio of the “Time Per
Element Cycle” values.
