Gahow Wang 445e491123 Add vLLM v0.18.1 source tree with KV transfer abort fix
third_party/vllm/ now tracked in git for direct patch management.
Based on vLLM v0.18.1 release with one patch applied:

  vllm/v1/core/sched/scheduler.py:
    Replace fatal assert with graceful skip when KV transfer callback
    arrives for an already-aborted request during PD disaggregated serving.

Future vLLM modifications should be made directly in third_party/vllm/
and committed normally. The patches/ directory is kept as documentation
of what changed from upstream.

Usage Stats Collection

vLLM collects anonymous usage data by default to help the engineering team better understand which hardware and model configurations are widely used. This data allows them to prioritize their efforts on the most common workloads. The collected data is transparent, does not contain any sensitive information.

A subset of the data, after cleaning and aggregation, will be publicly released for the community's benefit. For example, you can see the 2024 usage report here.

What data is collected?

The list of data collected by the latest version of vLLM can be found here: vllm/usage/usage_lib.py

Here is an example as of v0.4.0:

??? console "Output"

```

You can preview the collected data by running the following command:

tail ~/.config/vllm/usage_stats.json

Opting out

You can opt out of usage stats collection by setting the VLLM_NO_USAGE_STATS or DO_NOT_TRACK environment variable, or by creating a ~/.config/vllm/do_not_track file:

# Any of the following methods can disable usage stats collection
export VLLM_NO_USAGE_STATS=1
export DO_NOT_TRACK=1
mkdir -p ~/.config/vllm && touch ~/.config/vllm/do_not_track
