* Try IQ4_NL with blocks of 64 - does not look good * iq4_xs: go to super-blocks of 256 and 6-bit scales for blocks of 32 * iq4_xs: CUDA works - 133.2 t/s * iq4_xs: AVX2 dot product * iq4_xs: ARM_NEON dot product * iq4_nl: Metal implementation As usual, Metal / Apple Silicon don't like my quants. * iq3_xs: minor fix * iq4_xs: shrink by using IQ3_S for attn_k and attn_q * iq4_xs: revert using IQ3_S for attn_k and attn_v PPL vs size is good, but CPU performance suffers: on M2 Max TG-128 drops to 21.7 t/s from 28.8, and on a Ryzen-7950X to 14.5 t/s from 15.8 t/s. On CUDA we have 135 t/s when using IQ3_S vs 133 t/s with pure IQ4_XS. * Fix CI * iq4_xs: Added forgotten check for 256 divisibility --------- Co-authored-by: Iwan Kawrakow <iwan.kawrakow@gmail.com>

// GGML Tensor Library
|
|
//
|
|
// This documentation is still a work in progress.
|
|
// If you wish some specific topics to be covered, feel free to drop a comment:
|
|
//
|
|
// https://github.com/ggerganov/whisper.cpp/issues/40
|
|
//
|
|
// ## Overview
|
|
//
|
|
// This library implements:
|
|
//
|
|
// - a set of tensor operations
|
|
// - automatic differentiation
|
|
// - basic optimization algorithms
|
|
//
|
|
// The aim of this library is to provide a minimalistic approach for various machine learning tasks. This includes,
|
|
// but is not limited to, the following:
|
|
//
|
|
// - linear regression
|
|
// - support vector machines
|
|
// - neural networks
|
|
//
|
|
// The library allows the user to define a certain function using the available tensor operations. This function
|
|
// definition is represented internally via a computation graph. Each tensor operation in the function definition
|
|
// corresponds to a node in the graph. Having the computation graph defined, the user can choose to compute the
|
|
// function's value and/or its gradient with respect to the input variables. Optionally, the function can be optimized
|
|
// using one of the available optimization algorithms.
|
|
//
|
|
// For example, here we define the function: f(x) = a*x^2 + b
|
|
//
|
|
// {
|
|
// struct ggml_init_params params = {
|
|
// .mem_size = 16*1024*1024,
|
|
// .mem_buffer = NULL,
|
|
// };
|
|
//
|
|
// // memory allocation happens here
|
|
// struct ggml_context * ctx = ggml_init(params);
|
|
//
|
|
// struct ggml_tensor * x = ggml_new_tensor_1d(ctx, GGML_TYPE_F32, 1);
|
|
//
|
|
// ggml_set_param(ctx, x); // x is an input variable
|
|
//
|
|
// struct ggml_tensor * a = ggml_new_tensor_1d(ctx, GGML_TYPE_F32, 1);
|
|
// struct ggml_tensor * b = ggml_new_tensor_1d(ctx, GGML_TYPE_F32, 1);
|
|
// struct ggml_tensor * x2 = ggml_mul(ctx, x, x);
|
|
// struct ggml_tensor * f = ggml_add(ctx, ggml_mul(ctx, a, x2), b);
|
|
//
|
|
// ...
|
|
// }
|
|
//
|
|
// Notice that the function definition above does not involve any actual computation. The computation is performed only
|
|
// when the user explicitly requests it. For example, to compute the function's value at x = 2.0:
|
|
//
|
|
// {
|
|
// ...
|
|
//
|
|
// struct ggml_cgraph * gf = ggml_new_graph(ctx);
|
|
// ggml_build_forward_expand(gf, f);
|
|
//
|
|
// // set the input variable and parameter values
|
|
// ggml_set_f32(x, 2.0f);
|
|
// ggml_set_f32(a, 3.0f);
|
|
// ggml_set_f32(b, 4.0f);
|
|
//
|
|
// ggml_graph_compute_with_ctx(ctx, &gf, n_threads);
|
|
//
|
|
// printf("f = %f\n", ggml_get_f32_1d(f, 0));
|
|
//
|
|
// ...
|
|
// }
|
|
//
|
|
// The actual computation is performed in the ggml_graph_compute() function.
|
|
//
|
|
// The ggml_new_tensor_...() functions create new tensors. They are allocated in the memory buffer provided to the
|
|
// ggml_init() function. You have to be careful not to exceed the memory buffer size. Therefore, you have to know
|
|
// in advance how much memory you need for your computation. Alternatively, you can allocate a large enough memory
|
|
// and after defining the computation graph, call the ggml_used_mem() function to find out how much memory was
|
|
// actually needed.
|
|
//
|
|
// The ggml_set_param() function marks a tensor as an input variable. This is used by the automatic
|
|
// differentiation and optimization algorithms.
|
|
//
|
|
// The described approach allows to define the function graph once and then compute its forward or backward graphs
|
|
// multiple times. All computations will use the same memory buffer allocated in the ggml_init() function. This way
|
|
// the user can avoid the memory allocation overhead at runtime.
|
|
//
|
|
// The library supports multi-dimensional tensors - up to 4 dimensions. The FP16 and FP32 data types are first class
|
|
// citizens, but in theory the library can be extended to support FP8 and integer data types.
|
|
//
|
|
// Each tensor operation produces a new tensor. Initially the library was envisioned to support only the use of unary
|
|
// and binary operations. Most of the available operations fall into one of these two categories. With time, it became
|
|
// clear that the library needs to support more complex operations. The way to support these operations is not clear
|
|
// yet, but a few examples are demonstrated in the following operations:
|
|
//
|
|
// - ggml_permute()
|
|
// - ggml_conv_1d_1s()
|
|
// - ggml_conv_1d_2s()
|
|
//
|
|
// For each tensor operator, the library implements a forward and backward computation function. The forward function
|
|
// computes the output tensor value given the input tensor values. The backward function computes the adjoint of the
|
|
// input tensors given the adjoint of the output tensor. For a detailed explanation of what this means, take a
|
|
// calculus class, or watch the following video:
|
|
//

|
|
//
|
|
//
|
|
// ## Tensor data (struct ggml_tensor)
|
|
//
|
|
// The tensors are stored in memory via the ggml_tensor struct. The structure provides information about the size of
|
|
// the tensor, the data type, and the memory buffer where the tensor data is stored. Additionally, it contains
|
|
// pointers to the "source" tensors - i.e. the tensors that were used to compute the current tensor. For example:
|
|
//
|
|
// {
|
|
// struct ggml_tensor * c = ggml_add(ctx, a, b);
|
|
//
|
|
// assert(c->src[0] == a);
|
|
// assert(c->src[1] == b);
|
|
// }
|
|
//
|
|
// The multi-dimensional tensors are stored in row-major order. The ggml_tensor struct contains fields for the
|
|
// number of elements in each dimension ("ne") as well as the number of bytes ("nb", a.k.a. stride). This allows
|
|
// to store tensors that are not contiguous in memory, which is useful for operations such as transposition and
|
|
// permutation. All tensor operations have to take the stride into account and not assume that the tensor is
|
|
// contiguous in memory.
|
|
//
|
|
// The data of the tensor is accessed via the "data" pointer. For example:
|
|
//
|
|
// {
|
|
// const int nx = 2;
|
|
// const int ny = 3;
|
|
//
|
|
// struct ggml_tensor * a = ggml_new_tensor_2d(ctx, GGML_TYPE_F32, nx, ny);
|
|
//
|
|
// for (int y = 0; y < ny; y++) {
|
|
// for (int x = 0; x < nx; x++) {
|
|
// *(float *) ((char *) a->data + y*a->nb[1] + x*a->nb[0]) = x + y;
|
|
// }
|
|
// }
|
|
//
|
|
// ...
|
|
// }
|
|
//
|
|
// Alternatively, there are helper functions, such as ggml_get_f32_1d() and ggml_set_f32_1d() that can be used.
