Advanced Computer Concepts for The (Not So) Common Chef: First Some Terminology Part 2

OF COURSE, I KNOW WHAT A THREAD IS….DON’T I?

Now that we know what a core is, let’s dive into another source of confusion.

This section gets a little deeper into techno babble than I wanted for this series of blogs. If you are so inclined, my gourmet readers, you can either skip or read on. I believe the rest of the blogs can be understood with or without this little aside. But for those of you who are already familiar with threading, it may give you more insight than would be the case otherwise.

Advanced Computer Concepts For The (Not So) Common Chef: Terminology Pt 1

Before we start, I will use the next two blogs to clear up some terminology. If you are familiar with these concepts, I give you permission to jump to the next section.  I suggest any software readers still check out the other blog about threads. There is a lot of confusion, even among us software professionals.

Measuring Power on Intel® Xeon Phi™ Product Family Devices

Understanding power measurements and the issues associated with various power measurement methodologies is key to utilizing, procuring and deploying large HPC (High Performance Computing) clusters along with maximizing bottom line profit in the enterprise world. In the HPC space, large FLOPs/watt ratios are now a key design and procurement requirement as the operating costs of today’s petascale systems are on par with the acquisition costs of the actual supercomputer hardware itself (Subramaniam & Wu-chun, 2010).

  • Advanced Computer Concepts For The (Not So) Common Chef: Introduction

    While talking to a very intelligent but non-engineer colleague, I found myself needing to explain the threading and other components of the Intel® Xeon Phi™ ⅹ100 and ⅹ200 architectures. The first topic that came up was hyper-threading, and more specifically, the coprocessor’s version of hyper-threading. Wracking my brain, I finally hit upon an analogy that seemed to suit: the common kitchen.

    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.
