ABSTRACT:
Parallelization of a program is performed by creating a distilled version of the program having higher execution speed but with unverified execution. The distilled program is executed rapidly to create state snapshots of the program that may be forwarded to secondary processors for execution of the actual program in parallel with other secondary processors similarly allocated. Each state snapshot is verified as the task is executed on a secondary processor by the preceding processor. The degree of parallelization is limited only by the speed up of the distilled program.
