چکیده
DEFINITION OpenMP is an application programming interface for parallelizing sequential programs written in C, C++, and Fortran on shared-memory platforms. It provides a collection of compiler directives, a runtime library, and environment variables to enable programmers to specify the parallelism they desire to exploit in a program.

How to Reconcile Event-Based Performance Analysis with Tasking in OpenMP
With version 3.0, the OpenMP specification introduced a task construct and with it an additional dimension of concurrency. While offering a convenient means to express task parallelism, the new construct presents a serious challenge to event-based performance analysis. Since tasking may disrupt the classic sequence of region entry and exit events, essential analysis procedures such as reconstru...

چکیده امروزه شاهد گسترش روزافزون و اجتناب ناپذیر استفاده از رایانه‌ها در علوم و صنایع مختلف به منظور پردازش داده‌ها و انجام محاسبات هستیم. در این بین حجم محاسبات علمی در برخی از صنایع همچون صنعت هوافضا به دلیل سنگینی و پیچیدگی محاسبات میزان بالایی از پردازش را می‌طلبد و همچنین مقابله به موقع با چالش‌های فراوان پیش رو، نیاز به سرعت را نیز افزایش میابد. نیاز به دستیابی روش‌های نوینی که به ن...
متن کاملSkeleton driven transformations for an OpenMP compiler
In this paper we present a technique based on code templates, oriented to source to source code transformations for OpenMP parallelization. Our goal is to provide an OpenMP compilation infrastructure that includes a reconfigurable code generation phase, targetting different OpenMP runtime systems or explore different translation strategies for OpenMP constructs. We describe the main OpenMP tran...
متن کاملAn Operational Semantic Basis for OpenMP Race Analysis
OpenMP is the de facto standard to exploit the on-node parallelism in new generation supercomputers. Despite its overall ease of use, even expert users are known to create OpenMP programs that harbor concurrency errors, of which one of the most insidious of errors are data races. OpenMP is also a rapidly evolving standard, which means that future data races may be introduced within unfamiliar c...
