Cross-Platform Parallel Programming in Parray: A Case Study
Parray (or Parallelizing ARRAYs) is an extension of C language that supports system-level succinct programming for heterogeneous parallel systems. Parray extends mainstream C programming with novel array types. This leads to shorter, more portable and maintainable parallel codes, while the programmer still has control over performance-related features necessary for deep manual optimization. This paper uses the case study on stepwise program refinement of matrix transposition to illustrate the basic techniques of Parray programming.
