It includes functionality similar to LAPACK, as well as iterative Sparse matrix solvers and preconditioners on the GPU. It is supported on Linux, MacOS, and Windows. This latest 2.0 release adds queues to the MAGMA BLAS functions for better thread support, and adds several new Sparse matrix solvers. It is available under a modified BSD license from http://icl.utk.edu/magma/software/ ------------------------------------------------------- From: Bruce Bailey [log in to unmask] Date: February 11, 2016 Subject: New Book, AIMD Dynamics and Distributed Resource Allocation Announcing the February 9, 2016, publication by SIAM of: AIMD Dynamics and Distributed Resource Allocation by M. Corless, C. King, R. Shorten, and F. Wirth xiv + 235 pages / Softcover / 978-1-611974-21-8 / List Price $84.00 / SIAM Member Price $58.80 / DC29 This is the first comprehensive book on the AIMD algorithm, the most widely used method for allocating a limited resource among competing agents without centralized control. The authors offer a new approach that is based on positive switched linear systems. It is used to develop most of the main results found in the book, and fundamental results on stochastic switched nonnegative and consensus systems are derived to obtain these results. The original and best known application of the algorithm is in the context of congestion control and resource allocation on the Internet, and readers will find details of several variants of the algorithm in order of increasing complexity, including deterministic, random, linear, and nonlinear versions. In each case, stability and convergence results are derived based on unifying principles. Basic and fundamental properties of the algorithm are described, examples are used to illustrate the richness of the resulting dynamical systems, and applications are provided to show how the algorithm can be used in the context of smart cities, intelligent transportation systems, and the smart grid.

From classical results such as Heron's theorem, Euler's conjecture on the rigidity of polyhedra, Maxwell's forces diagrams, and the link to positive semidefinite matrices, DG has seen a veritable "engineering renaissance" in the XX century. DG is used in architecture (rigidity of structures), spatial conformation of molecules from inter-atomic distances, localization of mobile sensors in communication networks, control of unmanned underwater vehicles, control of robotic arms, solution of problems in spatial logic, and more. One of the foremost problems in DG is that of completing a partially specified matrix so that it is a Euclidean distance matrix, either in a given dimension, or in any (unspecified) dimension. Schoenberg's link means that DG is tightly linked to Semidefinite Programming (SDP), which is one of the most popular tools to solve DG problems, especially in the field of sensor networks. Because so many diverse application fields appeal to DG, its development has been somewhat fragmented, with very similar concepts being introduced within separate communities with different names. The aims of this conference are: (i) to attempt to reconcile some of this fragmentation by inviting researchers from many different disciplines to take part; (ii) to facilitate communications of technical knowledge between the different application field communities working on DG; (iii) to provide incentives for unifying the field of DG. ------------------------------------------------------- From: Pedro Valero-Lara [log in to unmask] Date: February 13, 2016 Subject: Complex Problems over HPC Architectures, France, Aug 2016 2nd Workshop on Complex Problems over High Performance Computing Architectures (CPHPCA'16) Paris, France, August 24th-26th, 2016 The main proposal of CPHPCA is to provide a scenario to discuss how those problems compromising important challenges and high computational requirements can be mapped over current and upcoming high performance architectures.
