                                   GPUContext gCtx,
                                   String instName,
                                   MatrixObject left,

                                   boolean isRightTransposed)

Matrix multiply on GPU Examines sparsity and shapes and routes call to appropriate method from cuBLAS or cuSparse C = op(A) x op(B) The user is expected to call ec.releaseMatrixOutputForGPUInstruction(outputName);

Parameters:

ec - Current ExecutionContext instance

gCtx - a valid GPUContext

instName - name of the invoking instruction to recordStatistics.

left - Matrix A

right - Matrix B

outputName - Name of the output matrix C (in code generated after LOP layer)

isLeftTransposed - op for A, transposed or not

isRightTransposed - op for B, tranposed or not

Returns:

output of matrix multiply
