test our implementation of the Fast Hadamard Transform?

Revision en1, by ilyaraz, 2015-11-27 23:08:11

Hi all,

Can you help me test our implementation of the Fast Hadamard Transform? It will take you a couple of minutes provided that you have modern enough C and C++ compilers. I'm especially interested in testing it under OS X and 32-bit systems.

You would need to have gcc that would compile C99 and g++ that would compile C++11. Also, you would need make to build everything.

What you need to do:

  1. Tell me your OS and CPU.
  2. Download the code from http://ilyaraz.org/fht.zip and unzip.
  3. Run "make", tell me if something does not compile.
  4. Run "test", make sure it does not fail. Tell me, if it fails.
  5. Run "best_chunk" with n = 1024, 1048576, 134217728 and send me the outputs.

Thanks! Ilya
