AbstractXALT collects accurate, detailed, and continuous job-level and link-time data and stores that data in a database; all the data collection is transparent to the users. The data stored can be mined to generate a picture of the compilers, libraries, and other software that users need to run their jobs successfully, highlighting the products that researchers use. We showcase how data collected by XALT can be easily mined into a digestible format by presenting data from four separate HPC centers. XALT is already used by many HPC centers around the world due to its usefulness and complementariness to existing logs and databases. Centers with XALT have a much better understanding of library and executable usage and patterns. We also present new functionality in XALT - namely the ability to anonymize data and early work in providing seamless access to provenance data.
