In Java 8 specifically, a parallel stream is designed to leverage a multi-core architecture. Let’s see how you can use them to run our first attempt of calculating the variance in a faster way.

Sumatra will repurpose Java 8’s multi-core APIs called Stream or Lambda to enable both CPU or GPU computing, but it will need an extra layer of code for parallel execution.
