Abstract
Mechanisms for extracting data dependencies during runtime are provided. With these mechanisms, a portion of code having a loop is executed. A first parallel execution group is generated for the loop, the group comprising a subset of iterations of the loop less than a total number of iterations of the loop. The first parallel execution group is executed by executing each iteration in parallel. Store data for iterations are stored in corresponding store caches of the processor. Dependency checking logic of the processor determines, for each iteration, whether the iteration has a data dependence. Only the store data for stores where there was no data dependence determined are committed to memory.
