About CL-Math

Mathematics library taking advantage of OpenCL hardware acceleration. Written for UAA's CSCE 448 course.

Current Status

Single-precision floating-point square matrix multiplication is all that is currently implemented. May be extended to other operations in the future.

Usage

More documentation is available in the wiki.

"lib/cl-math.h" must be included in any code you wish to use it in.

#include <lib/cl-math.h>

Multiplication of square single-precision floating-point matrices is as simple as the following:

CLMath* math = new CLMath();

Matrix a = math -> CreateSquareMatrix(SIZE, INIT_RANDOM); // or INIT_ZEROES
Matrix b = math -> CreateSquareMatrix(SIZE, INIT_RANDOM); // or INIT_ZEROES
Matrix c;

math -> CLSquareMatrixMultiply(a, b, c, SIZE, DEVICE_TYPE_GPU); // or DEVICE_TYPE_CPU

The matrices can be printed to console as shown:

math -> PrintMatrix(c, SIZE);

Matrix elements can be directly interacted with as floating point values:

Matrix a = math -> CreateSquareMatrix(3, INIT_ZEROES);
a[1][1] = 5;

The CreateSquareMatrix function takes a side length as the first argument. Matrices are later accessed using zero-indexing, so a 3x3 matrix generated using CreateSquareMatrix(3, INIT_ZEROES) is valid from [0-2][0-2].
