Dear NA Digest Community,

In the past few months, we have had to address several technical
challenges associated with sending out the NA Digest. We believe we
have solved the problems at this point, but some of you may not have
received some of the past few issues of the digest via email.

Subject: Release 1.3.0.1 of librsb Sparse BLAS Software Library

The minor release 1.3.0.1 of the "librsb" library for high performance
sparse matrix computations based on the "Recursive Sparse Blocks"
(RSB) format is out and available for download.

librsb is mainly for iterative methods implementors; it features cache
efficient, multithreaded sparse matrix-vector multiplication, and it
is especially fast in the symmetric and transposed variants.  Many
options and further matrix operations are available.

Both Sparse BLAS and the own interfaces are supported (C/C++,
Fortran).  You can also use librsb transparently in a Matlab-style
fashion via the GNU Octave `sparsersb` package and command, or in
Python via the `pyrsb.rsb_matrix` class inspired by `scipy.sparse`
classes.

- This release improves the build process across operating systems
  (e.g. *BSD, IBM AIX, Mac OS), architectures (armhf,sparc64),
  compilers and shells.
- Numerous compatibility-oriented configure options.
- Full changes list on http://librsb.sourceforge.net/NEWS.TXT

The source code of librsb is LGPLv3 licensed.
