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.

“With Java 8, it’s a huge shift in how you code,” says Java developer Yoav Landman, CTO at JFrog, which provides tools for managing binaries.

Native support for HSA’s specifications in JVMs is expected with Java 9 in 2015, and parallel algorithms will be executed natively in JVMs without extra layers of code. The JVM will recognize ...

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.
