Performance Data for CTH Performance Data for CTH CTH has been run on a large number of computing platforms over the years. This version has a particular set of input specifications that reduces the total computational time. The changes that were made relative to the benchmark version of this input deck to reduce the run time were to save no tracer data, write only the last restart dump, and discard the high explosive detonation products and case material at 40 microseconds problem time with no continuos discarding. The problem geometry is small and may fit in cache for most RISC and CISC type computers and is a good test of raw compute performance.
Many factors can effect performance including compiler options and cache size.
Since the geometry is small it does not make effective use of vector hardware. Some of the results were generated at Sandia and some were provided to us by the computer vendors.
