If we take a closer look in the scalar multiplication process, we can see that we can calculate the whole vector at once: In the scalar code, Vec.x is multiplied with the first four elements of the matrix. Those four elements are represented as the first line of the matrix, and are a...

With the M4D macro in place, implement the matrix multiplication function in mat4.cpp. Don't forget to add the function declaration to mat4.h. Remember that the (2, 1) element, for example, should take the dot product of row 2 from matrix a and column 1 of matrix b: mat4 operat...

>>It's funny how in college they tell you that the programmer need not worry with the low level issues of hardware implementation, yet even a simple problem such as matrix multiplication can cause such problems.This is the difference between theory and practice. QED (Quite Easily Doh...
This brings me to the topic at hand: does anyone have a good idea for how to fuse dequantization and general matrix multiplication in ggml? I think I could at the very least do a basic implementation that at least greatly reduces VRAM usage but it may perform significantly worse for promp...
