Scientific Workflow Management in Grids
Research Guide
What is Scientific Workflow Management in Grids?
Scientific Workflow Management in Grids orchestrates complex, data-intensive computational pipelines across distributed grid resources using engines like Pegasus and Taverna.
Systems like Pegasus map abstract workflows to grid sites for execution (Deelman et al., 2005, 1213 citations). Taverna enables bioinformatics workflow composition via Web services (Oinn et al., 2004, 1617 citations). Yu and Buyya (2005, 829 citations) classify grid workflow systems by architecture and features.
Why It Matters
Pegasus supports reproducible astronomy pipelines on grids, reducing setup time by abstracting resource details (Deelman et al., 2005). Taverna accelerates bioinformatics discoveries by integrating tools for in silico experiments (Oinn et al., 2004). These systems enable e-science scalability, as in hybrid grid-cloud transitions modeled by CloudSim (Calheiros et al., 2010, 4861 citations).
Key Research Challenges
Resource Heterogeneity Handling
Grids feature diverse compute nodes and networks, complicating workflow mapping. Pegasus addresses this via abstract representations (Deelman et al., 2005). Adaptive scheduling remains difficult across failures (Yu and Buyya, 2005).
Provenance and Reproducibility
Tracking data lineage in distributed executions ensures scientific validity. Taverna logs workflow enactments for bioinformatics (Oinn et al., 2005, 653 citations). Best practices highlight versioning needs (Wilson et al., 2014, 698 citations).
Deadline-Constrained Scheduling
Grid workflows must meet time bounds amid variability. Abrishami et al. (2012, 648 citations) propose algorithms for Iaas clouds adaptable to grids. Timing anomalies exacerbate issues (Graham, 1969, 2338 citations).
