I thought multi-threading was taking a single large process and splitting it into multiple processes to speed up the overall process. I know when working in the mainframe days, a difference between the CDC and Cray processors was the Cray was better at multi-threading. My cousin worked on a project that was able to take programs not written to multi-thread but would make them able to multi-thread.
