It has been a while since my last post here, but I’m back! I had access to the French version of this book, thanks to the publisher.
CUDA is now in the trend, and there are several books, one of them I’ve also reviewed.

We know now that we won’t have the same serial computing increase we had in the last decades. We have to cope with optimizing serial codes, and programming parallel and concurrent ones, and this means that all coders have to cope with this paradigm shift. If computer scientists are aware of the tools to use, it is not the same for the “average” scientist or engineer. And this is the purpose of this book: educate the average coder.

Massively parallel processors are in the mood today. We had small parallel processors with a few cores and the ability to launch serevral threads on one core, we have now many cores on one processor and at the other end of the spectrum, we have GPUs. CPUs vendors are now going in this direction with Larabee and Fusion, and GPUs will still have more cores/threads/… It’s thus mandatory to understand this shift now.

I’ve played a little bit with Intel Parallel Studio. Let’s say it has been a pleasant trip out in the wildness of multithreaded applications.
Intel Parallel Studio is a set of tools geared toward multithreaded applications. It consists of three Visual Studio plugins (so you need a fully-fledged Visual Studio, not an Express edition):
This is an update of the review I’ve done for the beta version. Since this first review, I’ve tried the official first version.

Since this post, Intel has officially released Parallel Studio. This is why I’ve published a new, up-to-date review here.

Some months ago, I’ve decided to dig into raytracing, and more exactly interactive raytracing. So I’ve started writting my own library, based on several publications.
nVidia announced recently its own framework, Intel wants also to do raytracing on Larrabee, it is the current trend.

Some months ago, I had a TotalView tutorial, thanks to my job. Now, I’ve actually used it to debug one of my parallel applications and I would like to share my experience with fantastic tool.
First TotalView is not only a parallel debugger available on several Linux and Unix platforms. It also is a memory checker (MemoryScape and the TotalView plugin) as well as a reverse debugger, that is, you can roll back the execution of a program, even after it crashed (where it would be useless with a standard debugger like GDB).

Like other programming models, there are some patterns in selecting the right parallel solution when it comes to designing a parallel application. This is what this book is about. The solutions may be obvious, but patterns aften are.

I came across the issue of how to teach a trainee how to write a parallel finite-difference time-domain (FDTD) method. There are a lot of books on the FDTD, but only a few on parallel ones. So I’ve decided to go for this book, knowing that some chapters won’t apply to our job (wave equations). My goal was to seek a book that would explain the basics of my issues.

I had this discussion with one of my Ph.D. advisors some months ago when we talked about correctly using the computers we had then (dual cores), and I had almost the same one in my new job here: applied maths (finite differences, signal processing, …) graduate students are not taught how to use current computers, so how could they develop an HPC program correctly?
I think it goes even further than that, and it will be a part of this post. What I see is that trainees and newly-hired people (to some extent myself included) lack a lot of basic Computer Science knowledge, and even IT knowledge.
