For example‚ if each student record consists of an ID number and a GPA value‚ then a list of students can be represented as an array of structure: The same data can be stored as two arrays that "parallel" to each other‚ in the sense that the same index in them indicate data...
This is especially true for graph-based and tree-based data structures. In those cases, algorithms should create hierarchies of “divisions,” waiting for subtasks to complete before returning a partial result. Although less optimal in an array like the one in Figure 1, several levels of ...
The tree, hash table, and sorted array data structures for implementing the primitive operations of a search table are considered. It is argued that the tree structure suffers from the bottleneck problem created by the single entry point, namely, the root, resulting in a linear time complexity....

to a sequential implementation on a fast CPU, and compared to a parallel implementation in OpenGL on the same GPU. Due to the increasing power of commodity parallel processors such as GPUs, we expect to see data-parallel algorithms such as scan to increase in importance over the coming ...
There are many data structure-specific partitioning techniques you might want to apply, certainly too many to enumerate in this column. So we’ll just focus on a common technique, which is to assign disjoint ranges of elements from the array to each partition. We simply calculate a stride whi...
TheBatchBlock<T>class operates in eithergreedyornon-greedymode. In greedy mode, which is the default, aBatchBlock<T>object accepts every message that it is offered and propagates out an array after it receives the specified count of elements. In non-greedy mode, aBatchBlock<T>object postpone...
The data should be aligned in a structure-of-array (SoA) manner in which all populations of a given type that communicate during the streaming step, are aligned at consecutive memory addresses. After this rearrangement, even a relatively straightforward LBM algorithm gets close to 80% of the me...
The projecting of the memory which has such non-conventional features as parallelism and multidimensionality of storage media, multiformativity of data access is the complex problem. Payment for the new memory features is a complication of hardware. In this respect the dyadic allocations give certain...
