Distributed Array Management Scheme for Data-parallel Compilers

International audienceHigh Performance Fortran and other similar languages have been designed as a means to express portable data parallel programs for distributed memory machines. As data distribution is a key-feature for exploiting the parallelism of applications, a crucial point for HPF compilers is their ability to manage efficiently distributed arrays. We present in this paper an innovative method to allocate local blocks and temporaries for received values and to manage the associated access mechanisms. The performance of these access mechanisms is measured and experimental results on the use of this array management within an existing compiler are shown
