Publication number: 20180157526Abstract: A quasi-automatic method is provided to parallelize user programs with little or no changes in their original design, implementation or compiled binary code. The users issues a simple indication to inform a runtime system about the intent to run the programs in a parallel or distributed manner, and the runtime system executes a plurality of programs based on the original program to conduct the same computation with parallelization. The semantics of the original program is reused, and task instances are created based on the semantics and executed in parallel or distributedly. The method provides an easy yet reliable method for accelerating computation by distributing the original program processes on multiple computers. Through a semantics-aware I/O control and coordination, the runtime system improves the consistency between the logical result data generated by the parallel computation and the expected result data from the original program should it be executed on one computer.Type: ApplicationFiled: January 31, 2017Publication date: June 7, 2018Inventors: Lin Gu, Zhiqiang Ma, Xinjie Yu, Zhaohua Li
