 It is a set of tools that convert a textual human readable dataflow language into a graph format (named "IF1" - Intermediary Form 1).Part of the SISAL project also involved converting this graph format into runable C code.In 2010 SISAL saw a brief resurgence when a group of undergraduates at Worcester Polytechnic Institute investigated implementing a fine-grain parallelism backend for the SISAL language.
