Array optimizations for high productivity programming languages
While the HPCS languages (Chapel, Fortress and X10) have introduced improvements in programmer productivity, several challenges still remain in delivering high performance. In the absence of optimization, the high-level language constructs that improve productivity can result in order-of-magnitude …
