// - Kernel 1: inspired by a Qualcomm optimized GPU kernel with 2D register tiling
//   https://developer.qualcomm.com/blog/matrix-multiply-adreno-gpus-part-2-host-code-and-kernel
// Both are fully configurable (and tunable!) using many parameters. Both kernels support
// different data-types (SGEMM/DGEMM/CGEMM/ZGEMM/HGEMM) through a pre-processor define.

// For kernel 0 matrices are accessed as follows:
// A: [k*M + m], with 'k' ranging from 0:K and 'm' from 0:M (m,k,m)
// B: [k*N + n], with 'k' ranging from 0:K and 'n' from 0:N (n,k,n)
// C: [n*M + m], with 'n' ranging from 0:N and 'm' from 0:M (m,n,m)
// For kernel 1, both A and C are transposed w.r.t. the above
//
// Or as an image (assuming column-major)
