  14. SwinDeW-C: Overview 14

  15. SwinDeW-C: Simulation Environment SwinDeW-C is developed based on SwinDeW and SwinDeW-G . It is currently running at Swinburne University of Technology, which is composed of 10 servers and 10 high-end PCs. To simulate the cloud computing environment, we set up VMware software on the physical servers and create virtual clusters as data centres. Every data centre created is composed of 8 virtual computing nodes with storages, and we deploy an independent Hadoop file system on each data centre. SwinDeW-C runs on these virtual data centres that can send and retrieve data to and from each other. Through a user interface at the applications layer, which is a Web based portal, we can deploy workflows and upload application data. 15

  16. Research Topics • Workflow Temporal Verification in Scientific Workflow Systems • Constraint Setting (BPM, CCPE), Checkpoint Selection (ICSE, TOSEM), Temporal Verification (TASE, CCPE), Exception Handling (ACOWR, JSS, TSE) • Data Management in Cloud Workflow Systems • Intermediate Data Storage Strategy, Data Replacement, Data Replication (IPDPS, CCPE, FGCS) • Security and Privacy in Cloud Workflow Systems

  26. Tips: • Read the latest papers previously published in the conference or journals you want to submit: get to know the template, the style and etc. • Cite the papers previously published in the conference or journals: get to know the PC Chair’s and PC member’s recent work. • Structure is most important! • Related work is really important! Not only introduce them, but also point out their pros and cons. • Evaluation is really important! • Do not use unfamiliar words! See what other people used • Do not use complex sentences if not necessary! Short and simple is the best. 26
