hipudding 1bdd8ae19f [CANN] Add Ascend NPU backend (#6035 ) * [CANN] Add Ascend NPU backend Ascend is a full-stack AI computing infrastructure for industry applications and services based on Huawei Ascend processors and software. CANN (Compute Architecture of Neural Networks), developped by Huawei, is a heterogeneous computing architecture for AI. Co-authored-by: wangshuai09 <391746016@qq.com> * delete trailing whitespaces * Modify the code based on review comment * Rename LLAMA_CANN to GGML_CANN * Make ggml-common.h private * add ggml_cann prefix for acl funcs * Add logging for CANN backend * Delete Trailing whitespace --------- Co-authored-by: wangshuai09 <391746016@qq.com>		2024-07-17 14:23:50 +03:00

Multiple values can be given for each parameter by separating them with ',' or by specifying the parameter multiple times.

llama-bench can perform three types of tests:

Prompt processing (pp): processing a prompt in batches (-p)
Text generation (tg): generating a sequence of tokens (-n)
Prompt processing + text generation (pg): processing a prompt followed by generating a sequence of tokens (-pg)

With the exception of -r, -o and -v, all options can be specified multiple times to run multiple tests. Each pp and tg test is run with all combinations of the specified options. To specify multiple values for an option, the values can be separated by commas (e.g. -n 16,32), or the option can be specified multiple times (e.g. -n 16 -n 32).

Each test is repeated the number of times given by -r, and the results are averaged. The results are given in average tokens per second (t/s) and standard deviation. Some output formats (e.g. json) also include the individual results of each repetition.

For a description of the other options, see the main example.

Note:

When using SYCL backend, there would be hang issue in some cases. Please set --mmp 0.
