This package benchmarks performance of a few standard linear algebra operations (such as a matrix product and QR, SVD and LU decompositions) across a number of different BLAS libraries as well as a GPU implementation.
To do so, it takes advantage of the ability to ‘plug and play’ different BLAS implementations easily on a Debian and/or Ubuntu system. The initial version supported * reference blas (refblas) which are unaccelerated as a baseline * Atlas which are tuned but typically configure single-threaded * Atlas39 which are tuned and configured for multi-threaded mode * Goto Blas which are accelerated and multithreaded * Intel MKL which are a commercial accelerated and multithreaded version. As for GPU computing, we use the CRAN package * gputools
For Goto Blas, the gotoblas2-helper script from the ISM in Tokyo can be used. For Intel MKL we use the Revolution R packages from Ubuntu 9.10.
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
