From Runnable and synchronized() to parallel() and atomically() (Part 1/2)
For about 15 years the Java multithreaded programming model has followed the evolution of CPUs and the growing needs of applications.
Multithreaded programming poses two challenges for the developer: parallelize the processes, and ensure consistency of the data,
while fully leveraging the computing power of modern multicore processors.
This lecture begins by describing precisely these challenges and their issues. It then describes the technical solutions available today,
whether in the JDK API or in the frameworks of the Java ecosystem. From the threads of Java 1.0, to the Fork / Join of Java 7, and the anticipated
parallel () of Java 8, from synchronized and volatile to STM and actors, everything will be explained. Some algorithm upcoming issues will also be
shown to illustrate the talk.
