clmatrix_t Struct Reference

Detailed Description

OpenCL boolean matrix data structure. Data is arranged in 32 bit words.

Words are stored in column-major order (as to optimise GPU memory access patterns).

Keeps two copies of matrix data: one in CPU memory and one in GPU memory. Methods are provided to move data back and forth.
