PSTSWM Parallel Performance

Performance Studies using

PSTSWM

Experiment A-1 Transpose LT Performance

These results represent the minimum execution time for each platform, using the optimal parallel implementation, math libraries where available, and the best available compilers. The legends list the platforms in alphabetical order. Results are presented for both MPI-only experiments and best over all communication libraries.
