Vectorization Gets Explicit with Intel’s Updated Parallel Tool

Intel Parallel Studio XE 2015′s explicit vectorization feature allows programmers to define SIMD and other loops that should split and run in parallel on separate compute nodes. Intel has released a new version of its HPC application development suite with support for more hardware and development languages and a simple …

Next-Gen Code Worthy of World’s Most Powerful Supercomputers

Project aims to maximize power of world’s largest supercomputers by breaking big apps into tiny pieces. Modern supercomputer designs take parallel computing to such an extreme that even applications designed specifically for massive computers with thousands of computing nodes aren’t able to recognize all the myriad computing resources available and …

Speculative Locks Are Powerful When Used with Caution

Speculative locks work closely with Transactional Synchronization Extensions (TSX), allowing for multiple threads to obtain a lock simultaneously. The technology is difficult to use and requires careful considerations on when to use it. Jeff Cogswell gives you the details. Back in April, I talked about Intel’s Transactional Synchronization Extensions (TSX) …

Supercomputer Helps Kill Cancer More Effectively

MD Anderson Cancer Center researchers are using supercomputer simulations to aid in the development of a new cancer treatment that combines radiation with real-time magnetic resonance imaging (MRI).  Today, when physicians give radiation treatment to patients, they rely on CT scan images of a tumor’s location that were taken prior …
