First and foremost, fork/join tasks should operate as “pure” in-memory algorithms in which no I/O operations come into play. Also, communication between tasks through shared state should be avoided as much as
In this work-efficient scan algorithm, we perform the operations in place on an array in shared memory. The algorithm consists of two phases: the reduce phase (also known as the up-sweep phase) and the down-sweep phase. In the reduce phase, we traverse the tree from leaves to root ...

The authors also discuss important issues such as algorithm engineering, memory hierarchies, algorithm libraries, and certifying algorithms. Moving beyond the sequential algorithms and data structures of the earlier related title, this book takes into account the paradigm shift towards the parallel ...

During the 1950s, parallel meant to share common memory with multiple processors. Today, parallel computing doesn’t only mean hardware parallelism but also software and application parallelism. It has become the mainstream computing architecture from laptops to the top end of computing. What is a ...
There was a time when machines were forced to use tapes to process large amount of data, loading smaller chunks into memory one at a time. The merge-sort sorting algorithm for example, is suitable for this kind of processing. Today we have bigger memories, but also big-data. File-based ...
The purpose of this book is to help you understand how to program shared-memory parallel machines without risking your sanity. By describing the algorithms and designs that have worked well in the past, we hope tohelp you avoid at least some of the pitfalls that have beset parallel projects....
55 MB total memory in use (0 MB lost due to fragmentation) MUT time 1.42s ( 0.36s elapsed) GC time 0.83s ( 0.21s elapsed) Total time 2.25s ( 0.57s elapsed) Relative to the sequential program, this is aspeedup of two on four cores. Not bad, but we ought to be able to do bett...
