ProActive Parallel Suite is an open-source software for enterprise workload orchestration, part of the OW2 community. A workflow model allows a set of executables or scripts, written in any language, to be defined along with their dependencies, so ProActive Parallel Suite can schedule and orchestrate executions while optimising the use of computational resources. ProActive Parallel Suite is based on the "active object" design pattern (see ) to optimise task distribution and fault-tolerance.
