Tsunami Data Benchmark

This benchmark examines the performance of emulators fit in parallel to multiple targets. The benchmark uses a set of tsunami simulations, where the inputs are 14 values of the seafloor displacement resulting from an earthquake, and the outputs are tsunami wave heights at different spatial locations. This benchmark fits 8, 16, 32, and 64 output points using 1, 2, 4, and 8 processes, and records the time required per emulator to perform the fitting. The actual performance will depend on the specific machine and the number of cores available. Once the number of processes exceeds the number of cores on the machine, the fitting time will increase, so the results will depend on the exact setup used. For reference, tests on a quad core MacBook Pro found that the fitting took roughly 1 second per emulator on a single core, with the time per emulator dropping by about a factor of 2 when 4 processes were used.
