From e7e4df031b9e29d4b55a4e0b0295187f6b213db1 Mon Sep 17 00:00:00 2001 From: slaren Date: Fri, 12 Jan 2024 20:07:38 +0100 Subject: llama : ggml-backend integration (#4766) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * llama : ggml-backend integration * ggml-backend : add names to buffers * fix unmap after loading * batched-bench : add tensor_split param * llama : check for null tensor_split * ggml-backend : increase GGML_MAX_BACKENDS * improve graph splitting, partial fix for --no-kv-offload * cuda : add ggml-backend split buffer support * cuda : do not create buffer types for devices that don't exist (fixes usage without CUDA devices available) * ggml : fix null backend dereference (#4807) * ggml : fix null backend dereference * ggml : also check ggml_backend_is_cpu * test-backend-ops : check buffer allocation failures * llama : add cparam (split_mode) and command line argument (--split-mode, -sm) to configure the split mode (none, layer or row) * ggml : fix mul_mat_id work size * llama : rewrite session kv load/set without graphs * minor * llama : only initialize used backends, free backends on context free * llama : abort ctx if cuda backend init fails * llama : rewrite lora with ggml-backend and compute on CPU ggml-ci * llama : only map to a backend buffer the region of the file mapping containing the tensors used in the buffer * opencl : add ggml-backend buffer type * cuda : only use batched_cublas with batched mat muls (fixes fp16 tg perf) * llama : on Metal, by default offload the full model ggml-ci * metal : page align the data ptr (#4854) * Apply suggestions from code review Co-authored-by: Johannes Gäßler * cuda : fix split buffer free * address review comments * llama-bench : add split-mode parameter * fix whitespace * opencl : fix double initialization * server : add --split-mode parameter * use async copy and compute to improve multi-gpu performance ggml-ci * use async memcpys to copy the graph outputs to the CPU * fix opencl * use a host buffer for the cpu compute buffer for faster copies to the gpu --------- Co-authored-by: Georgi Gerganov Co-authored-by: Johannes Gäßler --- ggml-opencl.h | 16 +++++++++++++--- 1 file changed, 13 insertions(+), 3 deletions(-) (limited to 'ggml-opencl.h') diff --git a/ggml-opencl.h b/ggml-opencl.h index 44d05bd6..919b00d6 100644 --- a/ggml-opencl.h +++ b/ggml-opencl.h @@ -1,6 +1,7 @@ #pragma once #include "ggml.h" +#include "ggml-backend.h" #ifdef __cplusplus extern "C" { @@ -9,17 +10,26 @@ extern "C" { GGML_API void ggml_cl_init(void); GGML_API void ggml_cl_mul(const struct ggml_tensor * src0, const struct ggml_tensor * src1, struct ggml_tensor * dst); -GGML_API bool ggml_cl_can_mul_mat(const struct ggml_tensor * src0, const struct ggml_tensor * src1, struct ggml_tensor * dst); +GGML_API bool ggml_cl_can_mul_mat(const struct ggml_tensor * src0, const struct ggml_tensor * src1, const struct ggml_tensor * dst); GGML_API size_t ggml_cl_mul_mat_get_wsize(const struct ggml_tensor * src0, const struct ggml_tensor * src1, struct ggml_tensor * dst); GGML_API void ggml_cl_mul_mat(const struct ggml_tensor * src0, const struct ggml_tensor * src1, struct ggml_tensor * dst, void * wdata, size_t wsize); -GGML_API void * ggml_cl_host_malloc(size_t size); -GGML_API void ggml_cl_host_free(void * ptr); +// GGML_API void * ggml_cl_host_malloc(size_t size); +// GGML_API void ggml_cl_host_free(void * ptr); GGML_API void ggml_cl_free_data(const struct ggml_tensor* tensor); GGML_API void ggml_cl_transform_tensor(void * data, struct ggml_tensor * tensor); +// backend API + +// GGML_API ggml_backend_t ggml_backend_opencl_init(void); + +// GGML_API bool ggml_backend_is_opencl(ggml_backend_t backend); + +GGML_API ggml_backend_buffer_type_t ggml_backend_opencl_buffer_type(void); +// GGML_API ggml_backend_buffer_type_t ggml_backend_opencl_host_buffer_type(void); + #ifdef __cplusplus } #endif -- cgit v1.2.3
