Not recommended. - `--mlock`: Lock the model in memory, preventing it from being swapped out when memory-mapped. - `--no-mmap`: Do not memory-map the model. By default, models are mapped into memory, which allows the system to load only the necessary parts of the model as needed. +- `--numa STRATEGY`: Attempt one of the below optimization strategies that help on some NUMA systems +- `--numa distribute`: Spread execution evenly over all nodes +- `--numa isolate`: Only spawn threads on CPUs on the node that execution started on +- `--numa numactl`: Use the CPU map provided by numactl +if run without this previously, it is recommended to drop the system page cache before using this +see https://github.com/ggerganov/llama.cpp/issues/1437 + - `--numa`: Attempt optimizations that help on some NUMA systems. - `--lora FNAME`: Apply a LoRA (Low-Rank Adaptation) adapter to the model (implies --no-mmap). This allows you to adapt the pretrained model to specific tasks or domains. - `--lora-base FNAME`: Optional model to use as a base for the layers modified by the LoRA adapter. This flag is used in conjunction with the `--lora` flag, and specifies the base model for the adaptation. diff --git a/examples/server/server.cpp b/examples/server/server.cpp index 2decd776..912c750c 100644 --- a/examples/server/server.cpp +++ b/examples/server/server.cpp @@ -1855,7 +1855,10 @@ static void server_print_usage(const char *argv0, const gpt_params ¶ms, { printf(" --no-mmap do not memory-map model (slower load but may reduce pageouts if not using mlock)\n"); } - printf(" --numa attempt optimizations that help on some NUMA systems\n"); + printf(" --numa TYPE attempt optimizations that help on some NUMA systems\n"); + printf(" - distribute: spread execution evenly over all nodes\n"); + printf(" - isolate: only spawn threads on CPUs on the node that execution started on\n"); + printf(" - numactl: use the CPU map provided my numactl\n"); if (llama_supports_gpu_offload()) { printf(" -ngl N, --n-gpu-layers N\n"); printf(" number of layers to store in VRAM\n"); @@ -2264,9 +2267,17 @@ static void server_params_parse(int argc, char **argv, server_params &sparams, { params.use_mmap = false; } - else if (arg == "--numa") - { - params.numa = true; + else if (arg == "--numa") { + if (++i >= argc) { + invalid_param = true; + break; + } else { + std::string value(argv[i]); + /**/ if (value == "distribute" || value == "" ) { params.numa = GGML_NUMA_STRATEGY_DISTRIBUTE; } + else if (value == "isolate") { params.numa = GGML_NUMA_STRATEGY_ISOLATE; } + else if (value == "numactl") { params.numa = GGML_NUMA_STRATEGY_NUMACTL; } + else { invalid_param = true; break; } + } } else if (arg == "--embedding") { @@ -2497,7 +2508,8 @@ int main(int argc, char **argv) params.model_alias = params.model; } - llama_backend_init(params.numa); + llama_backend_init(); + llama_numa_init(params.numa); LOG_INFO("build info", {{"build", LLAMA_BUILD_NUMBER}, {"commit", LLAMA_COMMIT}}); |
