TavernaPBS plugin, developed by the Mackey Lab, Center for Public Health Genomics, University of Virginia, US, allows users to define workflows that can then be run using a computational cluster that uses a PBS queuing system. The workflows represent next generation sequencing analysis pipelines.

To most efficiently make use of their myriad of UNIX command line tools, the project has developed a custom Beanshell-based library to enable workflows composed of UNIX command line invocations. Furthermore, they have abstracted the command execution such that each step could be executed as an independent “job” on a remote high performance computing or grid environment. By doing so, they have essentially turned Taverna into a distributed workflow “compiler”.
