Assyr was a world-renowned expert in the field of numerical methods for stochastic differential equations and multiscale problems, where he made numerous landmark contributions. He was an energetic, enthusiastic, and passionate colleague, always open to new ideas and engaged in promoting mathematics at EPFL. He played an essential role in creating and shaping a unified Institute of Mathematics at EPFL. Assyr was very much appreciated by students as a teacher and a mentor. We have set up a tribute page to commemorate Assyr at https://link.inmemori.com/TvUauf The MATHICSE group at EPFL ------------------------------------------------------- From: Michele Martone [log in to unmask] Date: September 17, 2021 Subject: Release 1.2.0.10 of librsb, Sparse BLAS Software Library Version 1.2.0.10 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 is a bugfixes release; see detailed changes in the NEWS file. The source code of librsb is LGPLv3 licensed.
