As the new ccNUMA architecture became popular in recent years, parallel programming with compiler directives on these machines has evolved to accommodate new needs. In this study, we examine the effectiveness of OpenMP directives for parallelizing the NAS Parallel Benchmarks. Implementation details will be discussed and performance will be compared with the MPI implementation. We have demonstrated that OpenMP can achieve very good results for parallelization on a shared memory system, but effective use of memory and cache is very important.

Improve your understanding of the basics of Functional Requirements for Authority Data (FRAD): A Conceptual Model with this text and help readers create RDA authority records. RDA will be implemented by thousands of libraries in the United States and around the world. RDA streamlines the process of making library collections accessible through improved authority data, either on-site or virtually. Catalogers need to understand the FRAD model in order to create RDA authority records. The first book of its kind, Demystifying FRAD: Functional Requirements for Authority Data provides clear, applicable information to help catalogers get up to speed by explaining the Functional Requirements for Authority Data (FRAD): A Conceptual Model. It illustrates the Conceptual Model for Authority Data with specific examples. It provides many specific examples that explain the FRAD entities, the attributes of those entities, and the relationships between those entities. This book also includes some brief RDA authority records exemplifying the major FRAD relationships.
