twod::JagMHeurProbeVer< T, Pr, onedalgoY, onedalgoX > Class Template Reference

Finds least max proc load value by applying binary search over it. First cut direction is vertical. See section 3.2.2 PROBE-M algorithm of "E. Saule, E. O. Bas, U. V. Catalyurek, Load-Balancing Spatially Located Computations using Rectangular Partitions Paper, Tech. Report, ArXiv, no. arXiv:1104.2566v1, 2011". More...

T twod::JagMHeurProbeVer< T, Pr, onedalgoY, onedalgoX >::part ( int  procCount,
const Pr &  prefixSumArray,
util::RectList< T, Pr > &  parts 
) [virtual]

Applies a 2d partitioning algorithm to a given 2d prefixSumArray .

Parameters:
[in] procCount is the number of processors
[in] prefixSumArray first column and first row consists of zero only. But the borders of rectangles in rect_list never touch this area (index 0 in row or column)
[out] parts must be empty before calling this function. It will contain the partition after the function return
Returns:
the load of the most loaded rectangle of parts

Implements twod::PartBase< T, Pr >.
