Declarative Data Parallelism Using Parallel LINQ

Last updated: Wednesday, August 31, 2022

Published in: CODE Magazine: 2011 - January/February

Applications can be single threaded or multithreaded. A single-threaded application is one in which the processor executes threads in a sequence, i.e., a thread would be scheduled by the operating system only if the execution of the currently running thread is complete. This approach doesn’t provide much system throughput (a measure of the amount of work done in unit time).
