[None][chore] Update trtllm-bench documentation on setting FP8 KV cache #7885
Conversation
📝 WalkthroughWalkthroughDocumentation in perf-benchmarking guide updated to reflect a configuration change for forcing KV cache quantization: replaces kv_cache_dtype: "fp8" with kv_cache_config: dtype: fp8 in example YAML. No code or control-flow changes. Changes

467-469: Fix option name in the tip: usekv_cache_config.dtype.The tip still references the old key. Replace with the new surfaced field.
-```{tip} -The two valid values for `kv_cache_dtype` are `auto` and `fp8`. -``` +```{tip} +The two valid values for `kv_cache_config.dtype` are `auto` and `fp8`. +```
459-461: Clarify the condition under which forcing applies.“checkpoint precision is null” is ambiguous. Refer directly to the field in
hf_quant_config.json.-If you would like to force the KV cache quantization, you can specify the following in the YAML file to force the precision -when the checkpoint precision is `null`: +If you would like to force KV cache quantization when `kv_cache_quant_algo` in `hf_quant_config.json` is `null`, add:

463-465: KV cache dtype: use lowercasefp8/auto— no change requiredConfirmed: kv_cache_config.dtype / kv_cache_dtype use lowercase
fp8/autoin the docs and CLI; uppercaseFP8is used only forquant_algo/compute-precision examples and should remain uppercase.

run [--reuse-test (optional)pipeline-id --disable-fail-fast --skip-test --stage-list "A10-PyTorch-1, xxx" --gpu-type "A30, H100_PCIe" --test-backend "pytorch, cpp" --add-multi-gpu-test --only-multi-gpu-test --disable-multi-gpu-test --post-merge --extra-stage "H100_PCIe-TensorRT-Post-Merge-1, xxx" --detailed-log --debug(experimental)]Launch build/test pipelines. All previously running jobs will be killed.
--reuse-test (optional)pipeline-id(OPTIONAL) : Allow the new pipeline to reuse build artifacts and skip successful test stages from a specified pipeline or the last pipeline if no pipeline-id is indicated. If the Git commit ID has changed, this option will be always ignored. The DEFAULT behavior of the bot is to reuse build artifacts and successful test results from the last pipeline.--disable-reuse-test(OPTIONAL) : Explicitly prevent the pipeline from reusing build artifacts and skipping successful test stages from a previous pipeline. Ensure that all builds and tests are run regardless of previous successes.--disable-fail-fast(OPTIONAL) : Disable fail fast on build/tests/infra failures.--skip-test(OPTIONAL) : Skip all test stages, but still run build stages, package stages and sanity check stages. Note: Does NOT update GitHub check status.--stage-list "A10-PyTorch-1, xxx"(OPTIONAL) : Only run the specified test stages. Examples: "A10-PyTorch-1, xxx". Note: Does NOT update GitHub check status.--gpu-type "A30, H100_PCIe"(OPTIONAL) : Only run the test stages on the specified GPU types. Examples: "A30, H100_PCIe". Note: Does NOT update GitHub check status.--test-backend "pytorch, cpp"(OPTIONAL) : Skip test stages which don't match the specified backends. Only support [pytorch, cpp, tensorrt, triton]. Examples: "pytorch, cpp" (does not run test stages with tensorrt or triton backend). Note: Does NOT update GitHub pipeline status.--only-multi-gpu-test(OPTIONAL) : Only run the multi-GPU tests. Note: Does NOT update GitHub check status.--disable-multi-gpu-test(OPTIONAL) : Disable the multi-GPU tests. Note: Does NOT update GitHub check status.--add-multi-gpu-test(OPTIONAL) : Force run the multi-GPU tests in addition to running L0 pre-merge pipeline.--post-merge(OPTIONAL) : Run the L0 post-merge pipeline instead of the ordinary L0 pre-merge pipeline.--extra-stage "H100_PCIe-TensorRT-Post-Merge-1, xxx"(OPTIONAL) : Run the ordinary L0 pre-merge pipeline and specified test stages. Examples: --extra-stage "H100_PCIe-TensorRT-Post-Merge-1, xxx".--detailed-log(OPTIONAL) : Enable flushing out all logs to the Jenkins console. This will significantly increase the log volume and may slow down the job.--debug(OPTIONAL) : Experimental feature. Enable access to the CI container for debugging purpose.
