History of DynamoRIO

DynamoRIO originated from a collaboration between MIT and Hewlett-Packard in 2001. HP Labs created the Dynamo system for PA-RISC in the 1990's. A port to IA-32 was begun in 2000 and continued in collaboration with the Runtime Introspection and Optimization (RIO) group at MIT. The name originated from combining Dynamo with RIO.
