Software-based speculative parallelism for multicore processors

直到最近，一个普通的计算机程序员都可以利用集成电路芯片上不断增加的数以亿计的晶体管，而不需要额外的努力，因为它们都是由一个单独的处理器组成的。然而，技术限制最近迫使工业界转向多核处理器：一个芯片内的并行处理器。为了充分利用这种并行性，需要使用普通程序员不具备的技能对所有程序进行转换——这对加拿大软件行业来说是一个重大挑战。

Until recently, an average computer programmer could exploit the increasing hundreds of millions of transistors available on integrated circuit chips without any extra effort, since they were each organized as a single processor. However, technology limitations have recently forced industry to switch to multicore processors: parallel processors within a chip. To fully exploit this parallelism requires that all programs be transformed using skills which average programmers do not have---a significant challenge for the Canadian software industry.
