frechet::data::MatrixPool Class Reference

Detailed Description

memory pool for matrix objects (M4RI matrices mzd_t* and OpenCL matrices clm4rm_t*)

Keeps a list of recycled objects to reduce the need for new memory allocations. During the course of the poly-algorithm, all matrixes have similar sizes, so the chances for reusability are very good.
