Can a single-threaded program be made to use multiple cores?

Chris

The title says it all: is there a way to get an older program designed to use a single CPU core to use multiple CPU cores?

bwDraco

Unfortunately, a legacy program written for a single CPU cannot be forced to use multiple CPU cores. The usage of multiple CPU cores requires multiple threads, which need to communicate with each other while ensuring that race conditions and other problems do not occur. An older application cannot be made to use more than CPU core unless it is rewritten to do so, and only if the nature of the application allows it to be parallelized.
