Jan 1, 2025Monthly performance summary for 2025-01 focusing on the cp2k/cp2k module. A critical bug fix was implemented in the helium worm propagation routine to ensure consistent initial conditions across multiple helium environments. The fix synchronizes the 'work' array with the 'pos' array, maintaining a stable simulation state and preventing drift that affected reproducibility and accuracy. The change is tied to commit 52fc3dc60e4cda456728f7fe2a3447cb006ea529.
