one presenter exclaimed “Time spent optimizing for MIC is time well spent because it optimizes your code for non-MIC processors at the same time.”

Wellington and Austin: programming lots of cores

A couple of back-to-back opportunities to see great talks about harness lots of cores, and to give talks about programming options and why we do not need to give up on programmability in our quest for high performance. Wellington this week, Austin next week. Programming is not easy, and neither is parallel programming. Nevertheless, many [...]

Coarse-grained locks and Transactional Synchronization explained
By James Reinders (Intel) (48 posts) on February 7, 2012 at 2:55 pm
Comments (5)
Coarse-grained locks, and the importance of transactions, are key concepts that motivate why Intel Transactional Synchronization Extensions (TSX) is useful. I’ll do my best to explain them in this blog. In my blog “Transactional Synchronization in Haswell,” I describe new instructions (Intel TSX) that will improve the performance of coarse-grained locks. Understanding coarse-grained locks and [...]

TeraFLOP in 20W by 2020?
By James Reinders (Intel) (48 posts) on September 12, 2011 at 7:01 pm
Comments (0)
In 1996, a TeraFLOP was possible with only one computer in the world. By 2005, more than 500 computers could deliver a TeraFLOP. By 2020, many expect that an ExaFLOP machine (a million TeraFLOPs) can be built and consume only 20 MW of power. That means a TeraFLOP of computing will require only 20W. That's [...]

A Cilk Plus specification without an implementation would be noise. That is why we released a serious implementation first, followed shortly by a specification. Serious evaluation, production usage, and feedback are all possible as a result.

What Cilk™ Plus solves for C and C++ programmers

C and C++ were not designed as parallel programming languages. TBB solved this, quickly becoming the most popular solution. Cilk Plus complements TBB to address two important things which TBB did not: involving the compiler and direct mechanisms for data parallelism.
