Welcome to Computational Science Stack Exchange

Computational Science is a question and answer site for questions and answers about computational methods used in technical disciplines. It's built and run by you as part of the Stack Exchange network of Q&A sites. With your help, we're working together to build a library of detailed answers to every question about computational science.

We're a little bit different from other sites. Here's how:


Ask questions, get answers, no distractions

This site is all about getting answers. It's not a discussion forum. There's no chit-chat.

Just questions...

...and answers.

up vote

Good answers are voted up and rise to the top.

The best answers show up first so that they are always easy to find.

accept

The person who asked can mark one answer as "accepted".

Accepting doesn't mean it's the best answer, it just means that it worked for the person who asked.

Is there a reference-level implementation of BLAS in C/C++?

up vote 14 down vote favorite

The netlib BLAS implementation is an excellent reference, being mostly un-optimized and well documented (e.g. zgemm). However, it is in Fortran 77, making it somewhat inaccessible to those with a more modern programming education. Is there a reference-level implementation of BLAS, like netlib, in C/C++?

Have you looked at GNU Scientific Library's implementation? I find the source code to be sufficiently readable and the routines are well documented.

Netlib also produces CLAPACK, which includes BLAS, but it is just the fortran code run through f2c and is therefore a bit clunky (e.g. zgemm).


Get answers to practical, detailed questions

Focus on questions about an actual problem you have faced. Include details about what you have tried and exactly what you are trying to do.

Ask about...

  • Software packages or languages used in computational science
  • Algorithms or methods used to solve problems in applied mathematics
  • Appropriate methods for a given application area

Not all questions work well in our format. Avoid questions that are primarily opinion-based, or that are likely to generate discussion rather than answers.

Questions that need improvement may be closed until someone fixes them.

Don't ask about...

  • Anything not directly related to computational science
  • Questions that are primarily opinion-based
  • Questions with too many possible answers or that would require an extremely long answer

Tags make it easy to find interesting questions

All questions are tagged with their subject areas. Each can have up to 5 tags, since a question might be related to several subjects.

Click any tag to see a list of questions with that tag, or go to the tag list to browse for topics that interest you.

Improve posts by editing or commenting

Our goal is to have the best answers to every question, so if you see questions or answers that can be improved, you can edit them.

Use edits to fix mistakes, improve formatting, or clarify the meaning of a post.

Use comments to ask for more information or clarify a question or answer.

You can always comment on your own questions and answers. Once you earn 50 reputation, you can comment on anybody's post.

Remember: we're all here to learn, so be friendly and helpful!

Looks good to me. The documentation is a bit lacking, but the variable names are chosen well enough that I think its clear. I'll probably prepend the opening comment of the netlib BLAS routines. What exactly do you take issue with? Do you have an alternative? - Max Hutchinson Oct 28 '13 at 10:21
