Feb 1, 2025February 2025 Monthly Performance Instrumentation Summary for troyvvgroup/quemb focused on delivering observable performance improvements and better debugging capabilities. A new Timer class was introduced to measure and report execution times for core BE (Basis Expansion) and BEOPT (Basis Expansion Optimizer) operations. The instrumentation was integrated across critical paths including BE object initialization, ERI transformation, one-shot BE calculations, and optimization iterations. Timing data is printed to the console at higher verbosity levels to facilitate performance analysis, debugging, and data-driven tuning. This work enhances observability, accelerates bottleneck identification, and supports faster, targeted optimizations, contributing to better resource utilization and potential cost savings.
