Project

Integrating Darshan I/O Monitoring for Optimized Performance and Bottleneck Detection

Integrating Darshan I/O monitoring into Software Performance Optimization Team (SPOT) workflow at ATLAS. SPOT at ATLAS uses PerfMonMt to monitor job processes, and Darshan I/O Monitoring integration will allow SPOT to find and optimize possible I/O bottlenecks. This work will improve the monitoring tools set up by SPOT and allow more insights into optimizations on ATLAS.
