SciRUN [scirun] is an application begun in 1992 by National Center for Research Resources Center at Utah. SciRUN is a GUI scientific workbench that allows users to construct, manage, and debug simulations in domains such as physics and neurobiology. SciRUN simulations may be thought of as workflows since they allow for parallel and conditional execution of tasks. Some SciRUN applications allow for jobs to be run on a grid. SciRUN also provides extensive scientific visualization libraries.
Application in SciRUN is composed of
modules with specified input and output ports. Every port stands for a single, atomic data. The application execution follows a dataflow pattern - as soon as every input data for a particular module is available the module is executed. From this point of view produced data pieces behave similar to
tokens in
Petri net model.
Special properties of ports allow for cycles in the workflow graph (and thus for loops in execution) - very handy in interactive visualization environment of SciRUN.
SciRUN 2 implementation is conformant to Common Component Architecture
CCA specification and forms one of CCA Frameworks.
