资 源 简 介
ParaTrac is a profilier for parallel/distributed applications. It enables user to investigate their applications by non-intrusive tracing and auto-generated informative profiles.
Features
User-level tracing for both file system call and process statistics
Fine-grained profiles for application investigation
Profiling Data-Intensive Workflows
Data-intensive workflow are current target application of ParaTrac.
Low-level I/O profiles: General application behavior, I/O pattern/prediction, bottlenecks of underlying I/O systems.
Workflow profiles: Data-process interactions, processing pattern, inefficient scheduling detection, workflow debugging.
Here is some exemplary profiles of data-intensive workflows.
Future Directions
Memory reference profiling
Profile replaying
