The paper "Expression Templates Revisited: A Performance Analysis of Current Methodologies" in SIAM Journal of Scientific Computing references the "Blaze" linear algebra library. I haven't heard of it before, and can't seem to find online references. (The obvious google searches are giving the above paper back.)

So what is this library and where I can I learn more about it?

  • @cjs Have you tried contacting the authors of the paper? Or the author of reference 10 in the paper you mention? – GertVdE May 04 '12 at 10:15
  • @Ali Nothing is wrong with the paper, AFAIK. I just didn't see a reference for the Blaze library in the paper. – cjordan1 May 04 '12 at 15:43
  • @GertVdE I have not. I assumed it's commonly known in the numerical linear algebra community, and found it really annoying that the answer wasn't a simple google search away. Simplest to just answer it once and for all on and overflow-type site. – cjordan1 May 04 '12 at 15:45
  • @cjs I'm not a Lin Alg specialist but Blaze doesn't ring a bell at all. And the authors are also unknown to me. Sorry – GertVdE May 04 '12 at 17:52

Original answer (May 2012)

As far as I am concerned, the Blaze library has not been publicly released. A link to the software as well as the license for its use should have both been in the paper.

If you're interested in a modern, freely available, numerical linear algebra library that heavily leverages expression templates, I recommend Eigen.

Update (August 2012)

Blaze has been released, see Jack's answer for more details. I still personally recommend Eigen for those interested in working in numerical linear algebra with C++, but I'm glad to see a new openly released package in this space.

It seems that the library was just officially released on NA Digest. The source code and documentation are available on Google Code.

I have never heard of Blaze. However, after reading a bit in the article and searching for the namespace used, I found the physics library at one of the author's home page. As the paper says on p. 2

This “smart” ET methodology is implemented in the Blaze library that was developed in context of the pe physics engine

Which I take to mean that Blaze is the part of this PE library which does matrix computations. While the website says that the library has "complete documentation", I was unable to find neither library nor documentation on the web site. I think your only option is sending an email.
