Concurrency

Abstract

One of the biggest challenges in software development is writing software that will do more than one thing at a time. For decades, computers have been able to give an illusion of concurrency by quickly switching between tasks at a high rate, making it seem that they’re doing several things at once (when in reality, they’re continuously flipping from one task to the next, only “paying attention” to one at a time). Today’s computers frequently contain two or more computation cores, so that they really can do multiple things at once, simultaneously executing instructions on all cores at the same time.
