The Gozer workflow system is a production workflow authoring and execution platform that was developed at RiskMetrics Group. It provides a high-level language and supporting libraries for implementing local and distributed parallel processes. Gozer was developed with an emphasis on distributed processing environments in which workflows may execute for hours or even days. Key features of Gozer include: implicit parallelization that exploits both local and distributed parallel resources; survivability of system faults/shutdowns without losing state; automatic distributed process migration; and implicit resource management and control. The Gozer language is a dialect of Lisp, and the Gozer system is implemented on a service-oriented architecture.
