The engine log file (study/study.stt file) maintains detailed information on how much memory, disk space, elapsed time, and CPU time the engine uses as your job runs.

You can review this file to monitor resource requirements and performance. For example, reviewing Step Elapsed Time and Step CPU Time can help you predict how much time a particular job step will take at a future p-pass. Results inconsistent with the trends in this file can help you identify and fix performance problems and resource shortages.
