摘要： 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.

摘要： Mechanisms for performing data parallel function calls in code during runtime are provided. These mechanisms may operate to execute, in the processor, a portion of code having a data parallel function call to a target portion of code. The mechanisms may further operate to determine, at runtime by the processor, whether the target portion of code is a data parallel portion of code or a scalar portion of code and determine whether the calling code is data parallel code or scalar code. Moreover, the mechanisms may operate to execute the target portion of code based on the determination of whether the target portion of code is a data parallel portion of code or a scalar portion of code, and the determination of whether the calling code is data parallel code or scalar code.

摘要： Mechanisms for extracting data dependencies during runtime are provided. The mechanisms execute a portion of code having a loop and generate, for the loop, a first parallel execution group comprising a subset of iterations of the loop less than a total number of iterations of the loop. The mechanisms further execute the first parallel execution group and determining, for each iteration in the subset of iterations, whether the iteration has a data dependence. Moreover, the mechanisms commit store data to system memory only for stores performed by iterations in the subset of iterations for which no data dependence is determined. Store data of stores performed by iterations in the subset of iterations for which a data dependence is determined is not committed to the system memory.
