Fig. 16 Number of send calls in process number 0 on each domain decomposition from 16 to
512 processes in weak scaling
Fig. 17 Elapsed time of the decomposition on radial dimension from 16 to 512 processes in strong
scaling
almost same compared with MPI, as shown Fig. 18, while the elapsed time of the
decomposition on the radial dimension increases as the number of nodes increases,
as shown Fig. 17.
