How Sponsors and Developer Evangelists Can Win at Hackathons

I recently wrote here about the 2014 SoHacks hackathon, and doing so inspired me to do a general write-up on hackathon best practices based on my experience.  I hear comments now and then from those involved with developer evangelism that hackathons are a waste of time and money, and I believe this article can help put that broad claim to rest.

Controlling floating-point modes when using Intel® Threading Building Blocks

Intel® Threading Building Blocks (Intel® TBB) 4.2 Update 4 introduced enhanced support for managing floating-pointing settings. Floating-point settings can now be specified at the invocation of most parallel algorithms (including flow::graph). In this blog I want to pay attention to some peculiarities and details of the new feature and overall floating-point settings support in Intel TBB. This blog is not devoted to general floating-point support in the CPU.

  • Submissions open: High Performance Parallelism Gems

    We have all had our little discoveries and triumphs in identifying new and innovative approaches that increased the performance of our applications. Occasionally we find something more, something that could also help others, an innovative gem. You now have an opportunity to broadcast your successes more widely to the benefit of our community. You are invited to submit a proposal to a contribution-based book, working title, “High Performance Parallelism Gems – Successful Approaches for Multicore and Many-core Programming” that will focus on practical techniques for Intel® Xeon® processor and Intel® Xeon Phi™ coprocessor parallel computing. Submissions are due by May 29, 2014.
