paratrac

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 Publica
