- Intel Threading Tools and OpenMP
- Explicit threading methods, such as Windows threads or POSIX threads, use library calls to create, manage, and synchronize threads. Use of explicit threads requires an almost complete restructuring of affected code. On the other hand, OpenMP is a set of pragmas, API functions, and environment variables that enable one to...

- Intel Ct leaps ahead in multi-threaded development
- At Intel research day last week, one of the most impressive things I've seen to date in the parallel programming arena leapt out on center stage. I blogged earlier this month about "The death of single-threaded development" due to the systemic shift microprocessor progression. The OpenMP code took 172 lines...

- The death of single threaded development
- Applications use to get free performance boosts whenever the clock speed on the CPU and memory bus went up at an exponential rate. For two decades, applications just magically doubled in speed every two years without any requirement to redesign the code but the era the "free lunch" performance boosts...

- Extending OpenMP to Clusters
- OpenMP is a well-known parallel programming paradigm for shared-memory multiprocessors. In the past, OpenMP has been confined to Symmetric Multi-Processing SMP machines and teamed with Message Passing Interface MPI technology to make use of multiple SMP systems. A new system, Cluster OpenMP, is an implementation of OpenMP that can make...

- An Implementation of the POMP Performance Monitoring Interface for OpenMP Based on Dynamic Probes
- OpenMP has emerged as the standard for shared memory parallel programming. Unfortunately, it does not provide a standardized performance monitoring interface, such that users and tools builders could write portable libraries for performance measurement of OpenMP programs. This paper presents an implementation of a performance monitoring interface for OpenMP, based...

- Analyzing Overheads and Scalability Characteristics of OpenMP Applications
- Analyzing the scalability behavior and the overheads of Open-MP applications is an important step in the development process of scientific software. Unfortunately, few tools are available that allow an exact quantification of OpenMP related overheads and scalability characteristics. This paper presents a methodology which defines four overhead categories that can...

- OpenMP and Automatic Parallelization in GCC
- This paper describes the design and implementation of the OpenMP specification v2.5 in GCC. The implementation supports all the languages specified in the standard (C, C++ and Fortran), and it is generally available on any platform that supports POSIX threads. Emphasis is placed on the internal architecture and, in particular,...

- Load Balancing and OpenMP Implementation of Nested Parallelism
- Many problems have multiple layers of parallelism. The outer-level may consist of few and coarse-grained tasks. Next, each of these tasks may also be rich in parallelism, and be split into a number of fine-grained tasks, which again may consist of even finer subtasks, and so on. Here this paper...
