Abstract
A method for detecting a software-race condition in a program includes copying a state of a transaction of the program from a first core of a multi-core processor to at least one additional core of the multi-core processor, running the transaction, redundantly, on the first core and the at least one additional core given the state, outputting a result of the first core and the at least one additional core, and detecting a difference in the results between the first core and the at least one additional core, wherein the difference indicates the software-race condition.
