Apr 1, 2025In April 2025, Beast-MCMC delivered key CI/Testing infrastructure enhancements and a reliability upgrade for MCMC checkpointing in beast-dev/beast-mcmc. The CI workflow was stabilized by removing redundant test configurations, restoring Java 8 compatibility in CI, cleaning obsolete configs, and improving artifact visibility in CI logs, while aligning test data and XML configurations to yield faster, more reliable builds. In parallel, MCMC checkpointing reliability was enhanced by switching to a save frequency of every N iterations, ensuring consistent checkpoints and simpler recovery during long-running simulations. These changes reduced flaky tests, shortened feedback loops, and improved resilience of long-running experiments. The work demonstrates strong capabilities in CI/CD, test-data management, and numerical simulation robustness, delivering measurable business value through faster releases, higher reliability, and more predictable compute runs.

Nov 1, 2024November 2024: Strengthened stability and reliability of the MarginalLikelihoodEstimation workflow in beast-mcmc by adding robust handling for MIXED_EFFECTS_CLOCK. Implemented an explicit case for MIXED_EFFECTS_CLOCK in MarginalLikelihoodEstimationGenerator.java and enhanced the default error message to include unknown clock types for quicker debugging. This reduces runtime failures and accelerates issue resolution for users modeling with MIXED_EFFECTS_CLOCK. All changes tracked in beast-dev/beast-mcmc.
