They aren't similar, they couldn't be more different. One is about lots of small threads of execution communicating with each other and synchronizing, one is about a few instructions being able to be run in parallel because implicitly within the CPU there are different pipelines. They aren't just different, they are at completely opposite ends of the programming spectrum. There are literally the two extremes of trying to make throughput faster.
