The remainder of the paper is organized as follows. With and without communication optimization. We present experimental measurements for theĭistributed-memory parallel architecture, and compare the performance of benchmarks Pointer analysis and read/write sets for indirect references. Should be applica b le to other compilers that support Representation, and the presence of accurate read/write sets for both stack and heapdirected pointers 8, 111. In order to present relatively simple and efficient algorithms we take advantage of the structured nature of

This paper focuses on how to optimize the Primitives and to generate appropriate threads and synchronization. Thus, it is the EARTH-McCATĬompiler’s job to insert the appropriate communication To provide a high-level parallel language that exposesĬoarse-grain parallelism and data locality to the programmer, but hides all the details of communicationĪnd thread generation. That were written in EARTH-C, a high-level parallel dialect of C. To test our approach we implemented the techniquesĬ compiler, and we experimented with a collection of pointer-based benchmarks Transformation phase that selects the best location and Our framework consists of an analysis phase that determines where it is safe to move communication! and a To block or pipeline a group of remote requests together. Remote accesses with one access, and (3) transformations

Our framework includes: (1) code movement to issue remote reads earlier and writes later, (2)Ĭode transformations to replace repeated/redundant
