#pragma once // // 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: // // What is Automatic Differentiation? // https://www.youtube.com/watch?v=wG_nF1awSSY // // // ## 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. // // ## The matrix multiplication operator (ggml_mul_mat) // // TODO // // // ## Multi-threading // // TODO // // // ## Overview of ggml.c // // TODO // // // ## SIMD optimizations // // TODO // // // ## Debugging ggml // // TODO // // #ifdef GGML_SHARED # if defined(_WIN32) && !defined(__MINGW32__) # ifdef GGML_BUILD # define GGML_API __declspec(dllexport) # else # define GGML_API __declspec(dllimport) # endif # else # define GGML_API __attribute__ ((visibility ("default"))) # endif #else # define GGML_API #endif #ifdef GGML_MULTIPLATFORM # if defined(_WIN32) # define GGML_CALL # else # define GGML_CALL __attribute__((__ms_abi__)) # endif #else # define GGML_CALL #endif // TODO: support for clang #ifdef __GNUC__ # define GGML_DEPRECATED(func, hint) func __attribute__((deprecated(hint))) #elif defined(_MSC_VER) # define GGML_DEPRECATED(func, hint) __declspec(deprecated(hint)) func #else # define GGML_DEPRECATED(func, hint) func #endif #ifndef __GNUC__ # define GGML_ATTRIBUTE_FORMAT(...) #elif defined(__MINGW32__) # define GGML_ATTRIBUTE_FORMAT(...) __attribute__((format(gnu_printf, __VA_ARGS__))) #else # define GGML_ATTRIBUTE_FORMAT(...) __attribute__((format(printf, __VA_ARGS__))) #endif #include #include #include #include #define GGML_FILE_MAGIC 0x67676d6c // "ggml" #define GGML_FILE_VERSION 1 #define GGML_QNT_VERSION 2 // bump this on quantization format changes #define GGML_QNT_VERSION_FACTOR 1000 // do not change this #define GGML_MAX_DIMS 4 #define GGML_MAX_PARAMS 2048 #define GGML_MAX_CONTEXTS 64 #define GGML_MAX_SRC 10 #ifndef GGML_MAX_NAME #define GGML_MAX_NAME 64 #endif #define GGML_MAX_OP_PARAMS 64 #define GGML_DEFAULT_N_THREADS 4 #define GGML_DEFAULT_GRAPH_SIZE 2048 #if UINTPTR_MAX == 0xFFFFFFFF #define GGML_MEM_ALIGN 4 #else #define GGML_MEM_ALIGN 16 #endif #define GGML_EXIT_SUCCESS 0 #define GGML_EXIT_ABORTED 1 #define GGUF_MAGIC "GGUF" #define GGUF_VERSION 3 #define GGUF_DEFAULT_ALIGNMENT 32 #define GGML_UNUSED(x) (void)(x) #define GGML_PAD(x, n) (((x) + (n) - 1) & ~((n) - 1)) #define GGML_ASSERT(x) \ do { \ if (!(x)) { \ fflush(stdout);
