 // define this if you want to always fallback to MMQ kernels and not use cuBLAS for matrix multiplication
 // on modern hardware, using cuBLAS is recommended as it utilizes F16 tensor cores which are very performant
 // for large computational tasks. the drawback is that this requires some extra amount of VRAM:
