Subject: TOMS back issues available

I have a (probably) complete set of issues of ACM TOMS (Transactions
on Mathematical Software), starting with vol. 1, no. 1 (1975), to
vol. 40, no. 1 (2014). These are just collecting dust in my closet.
I am willing to donate them to the first responder who agrees to pay
shipping costs.

Subject: MAGMA 2.0 Released

MAGMA is on open-source library for dense and sparse linear algebra on
heterogeneous CPU + GPU systems. 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

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.

Subject: Distance Geometry, USA, Jul 2016

DIMACS Workshop on Distance Geometry: Theory and Applications
26-29 July 2016 at DIMACS, Rutgers University, NJ, USA

Distance Geometry (DG) is a field of geometry which focuses on
defining and working with geometrical objects using distances between
points rather than the points themselves. 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.

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. The goal of this workshop is to bridge
the gap between the theory of complex problems (computational fluid
dynamics, bio-informatics, linear algebra, big data computing,
deep-learning, data mining, ...) and high performance computing
platforms by proposing new trends/directions in programming.

Relevant topics include, but are not limited to:
- New strategies to improve performance
- Code adapting to take advantages of lastest features
- Numerical modeling for complex problems
- Communication, synchronization, load balancing
- Benchmarking, performance and numerical accuracy analysis
- Scalability of algorithms and data structures
- New programming models
- Auto-Tunning Computing Systems
- High level abstraction tools
