摘要

多核处理器的日益普及引起了人们对并行编程的兴趣。Cilk是C和c++的一种语言扩展,旨在简化共享内存多处理器系统的编程。Cilk中的工作窃取调度器被证明是高效的,并且保持了良好定义的空间边界。[1,2]确定性程序(即不使用锁结构的无竞争的Cilk程序)维护串行语义,并且这样一个运行在P个处理器上的Cilk程序将使用不超过相应串行程序所需堆栈空间的P倍。

Exploiting multicore systems with Cilk
The increasing prevalence of multicore processors has led to a renewed interest in parallel programming. Cilk is a language extension to C and C++ designed to simplify programming shared-memory multiprocessor systems. The workstealing scheduler in Cilk is provably efficient and maintains well-defined space bounds. [1, 2] A deterministic program (that is, a race-free Cilk program that uses no lock constructs) maintains serial semantics, and such a Cilk program running on P processors will use no more than P times the stack space required by the corresponding serial program.
