Benchmark the batched decoding performance of llama.cpp
Usage
There are 2 modes of operation:
prompt not shared
- each batch has a separate prompt of sizePP
(i.e.N_KV = B*(PP + TG)
)prompt is shared
- there is a common prompt of sizePP
used by all batches (i.e.N_KV = PP + B*TG
)
./llama-batched-bench -m model.gguf -c 2048 -b 2048 -ub 512 -npp 128,256,512 -ntg 128,256 -npl 1,2,4,8,16,32 [-pps]
# LLaMA 7B, F16, N_KV_MAX = 16384 (8GB), prompt not shared
./llama-batched-bench -m ./models/llama-7b/ggml-model-f16.gguf -c 16384 -b 2048 -ub 512 -ngl 99
# LLaMA 7B, Q8_0, N_KV_MAX = 16384 (8GB), prompt is shared
./llama-batched-bench -m ./models/llama-7b/ggml-model-q8_0.gguf -c 16384 -b 2048 -ub 512 -ngl 99 -pps
# custom set of batches
./llama-batched-bench -m ./models/llama-7b/ggml-model-q8_0.gguf -c 2048 -b 512 -ub 512 -ngl 999 -npp 128,256,512 -ntg 128,256 -npl 1,2,4,8,16,32
Sample results
PP
- prompt tokens per batchTG
- generated tokens per batchB
- number of batchesN_KV
- required KV cache sizeT_PP
- prompt processing time (i.e. time to first token)S_PP
- prompt processing speed ((B*PP)/T_PP
orPP/T_PP
)T_TG
- time to generate all batchesS_TG
- text generation speed ((B*TG)/T_TG
)T
- total timeS
- total speed (i.e. all tokens / total time)
