    In the multicore era, sequential programs need to be refactored for parallelism. The next version of Java provides ParallelArray, an array data structure that supports parallel operations over the array elements. For ...

    Effect systems are important for reasoning about the side effects of a program. Although effect systems have been around for decades, they have not been widely adopted in practice because of the large number of annotations ...

    The k-D tree is a well-studied acceleration data structure for ray tracing. It is used to organize primitives in a scene to allow efficient execution of intersection operations between rays and the primitives. The highest ...

    Object-oriented frameworks can make parallel programming easier by providing generic parallel algorithms such as map, reduce, or scan, and letting the user fill in the details with sequential code. However, such frameworks ...
