Table 1.
Least Runtime in seconds for the three single cell models when the maximum piece size factor (Fac) is varied. Also shown are the results for the standard maximum piece size factor of 0.3. Other columns are % Load Balance, Number of multisplit subtrees (Pieces), Number of split points (Rank of the reduced-tree matrix), Reduced-tree MPI Recv buffer size (Buf) in number of double precision data values, and the Reduced-tree (RT) computation time in seconds.
