v1.0.1

1.0.1 Bugfix Release

This Release:

1. Fixes a bug where cancelling multiple in-flight requests could crash the vllm server
2. Fixes a bug where granite-3.x-8b models were not detected correctly, leading to VLLM_SPYRE_REQUIRE_PRECOMPILED_DECODERS not functioning properly
3. Fixes a bug where the number of processors was not detected correctly for setting threading configs.
   1. VLLM_SPYRE_NUM_CPUS is now available as a manual override to set the number of cpu cores available to vllm
4. Fixes a bug where attempting to run pooling models in continuous batching mode would crash, instead of defaulting to static batching
5. Fixes a bug where the lower bound of FMS was not properly specified
6. Disables prompt logprobs completely because it's still broken
7. Updates the "simple compile backend" to inductor to align with vLLM

What's Changed

• disable prompt logprobs by @yannicks1 in #486
• [docs] update docs continuous batching by @yannicks1 in #485

v1.0.0

🎉 vllm-spyre v1.0.0 🎉

This release of vllm-spyre is compatible with the 1.0.0 version of the spyre runtime stack.

See the docs for a list of supported models and configurations

Supported Features:

• ⚡⚡⚡ Production-ready continuous batching (with VLLM_SPYRE_USE_CB=1) for a gpu-like user experience
• 🤓 Accurate text generation results with continuous batching for contexts up to 32k
• 🤏 Support for FP8-quantized models
• 🥅 Support for enforcing pre-compiled model graphs with VLLM_SPYRE_REQUIRE_PRECOMPILED_DECODERS=1

Known Issues:

• The container image for this release does not have the correct v1.0 spyre runtime stack installed and will not funciton properly, the containerfile is still for demonstration purposes only
• Logits processors (custom and builtin) are not applied to the first generated token (prefill phase). Users might have incorrect results for the sampling params: min_p, logit_bias and min_tokens.
• It is possible to crash the server with an IndexError and a StackTrace pointing at logits[self.logits_slice] = -float("inf") if sending and cancelling batches of requests with certain parameters; see #492
• The lower bound for ibm-fms is wrong, it should be <= 1.4.0. The lockfile contains a valid set of dependencies. See #493
• For reranker models, with the sendnn backend the outputs scores can be up to 15% different compared with a sentence-tranformers inference on GPU or CPU.
