在计算领域中，对提高设备性能增益的持续研究导致了多核处理器的出现，多核处理器包括一个以上的独立处理单元（核）。计算机硬件方面的这场革命要求软件程序员通过开发并行程序来开发处理能力。程序员更喜欢编写串行应用程序，因为串行代码比并行代码更容易实现他们的想法。因此，并行化这样的串行应用程序而不给开发人员带来太多负担变得至关重要。本文提出了一种自动并行化串行C代码的系统。提出的系统进行详细的依赖性分析，确定的“for”块，满足潜在的使用OpenMP框架被并行化的标准，确定在这样的潜在的“for”块，需要在一个关键的部分运行的区域。该系统保证了输入代码的正确性。此外，避免了执行后分析，即执行输入程序以监视资源的使用，这使得该系统比某些现有系统更快。
Continuous research to increase the performance gain of the device in the field of computing has led to the advent of multi-core processors, which include more than one independent processing unit (core). This revolution on the hardware-side of the computer demands the software programmers to exploit the processing power by developing parallel programs. Programmers prefer writing serial applications since it is easier to put their ideas into the form of serial code than a parallel one. Hence, parallelizing such serial applications without much burden on the developer becomes paramount. This paper proposes a system that automatically parallelizes serial C code. The system proposed performs detailed dependency analysis, identifies the ‘for’ blocks that satisfy the criteria of being potential to be parallelized using the OpenMP framework, identifies the regions in such potential ‘for’ blocks which need to be run in a critical section. The correctness of the input code is ensured by this system. Also, post execution analysis i.e. execution of the input program to monitor the usage of resources is avoided which makes this system faster than some of the existing systems.
