Mar 1, 2025

March 2025 monthly summary focusing on key accomplishments, with a focus on delivering end-to-end Boltz prediction capabilities and a critical reliability fix across Kubernetes/Dask workloads. Highlights include the introduction of a FastAPI Boltz prediction API that runs the boltz predict CLI as an asyncio subprocess to enable parallel requests and packaging results as a gzipped tar archive, along with adjustments to container resource limits for improved reliability. A Streamlit-based Boltz prediction UI was added, with updates to the FastAPI app to support asynchronous processing and GPU acceleration, new container images for FastAPI and Streamlit, integration of the Boltz model artifact, and enhanced prediction logic to accommodate async operation and optional MSA directories. A Go-based bug fix in Flyte introduced DeepCopy for TaskExecMetadata to prevent concurrent modifications of platformResources and overrideResources in Dask/Kubernetes environments, addressing a critical resource handling race condition. These efforts combined to boost throughput, reduce end-to-end latency under concurrent load, and strengthen resource safety and deployment reliability across the Boltz-enabled workflows.
