  • ZPL uses the array abstraction to implement a data parallel programming model.
  • Computer graphics processing is a field dominated by data parallel operations particularly linear algebra matrix operations.
  • OpenCL provides a cross-platform GPGPU platform that additionally supports data parallel compute on CPUs.
  • But, such performance can be achieved only on certain workloads ( data parallel computations, or SIMD ).
  • A data parallel job on an array of'n'elements can be divided equally among all the processors.
  • One important thing to note is that the locality of data references plays an important part in evaluating the performance of a data parallel programming model.
  • Code that performs a similar and typically small operation on a large collection of elements is called data parallel, and appears often in high-performance scientific applications.
  • As a unique feature, Muesli's data parallel skeletons automatically scale both on single-as well as on multi-core, multi-node cluster architectures.
  • This programming paradigm maps well to vector processors : there is an assumption that each invocation of a kernel within a batch is independent, allowing for data parallel execution.
  • In programming models such as CUDA designed for data parallel computation, an array of threads run the same code in parallel using only its ID to find its data in memory.
  • The county data parallel U . S . Labor Department statistics, which show San Jose and San Francisco as the two metropolitan areas with the highest pay in the United States last year.
  • Modules can be nested using the two tier model, where the outer level is composed of task parallel skeletons, while data parallel skeletons may be used in the inner level [ 64 ].
  • On the other hand, if we execute this job as a data parallel job on 4 processors the time taken would reduce to ( n / 4 ) * Ta + Merging overhead time units.
  • For a more detailed comparison of the MapReduce and PACT programming models you can read our paper / / " MapReduce and PACT-Comparing Data Parallel Programming Models " / / ( see our page ).
  • In the early 1990s PGI was deeply involved in the development of High Performance Fortran, or HPF, a data parallel language extension to Fortran 90 which provides a portable programming interface for a wide variety of architectures.
  • For addition of arrays in a data parallel implementation, let s assume a more modest system with two Central Processing Units ( CPU ) A and B, CPU A could add all elements from the top half of the arrays, while CPU B could add all elements from the bottom half of the arrays.
