Subject: In memoriam: Joseph F. Traub

It is my sad duty to inform you that Joseph F. Traub passed away on
Monday, August 24, in Santa Fe, NM. Joe's death was sudden and
unexpected, without any long suffering.

Joe had a long and distinguished career, having worked at Bell Labs,
the University of Washington, Carnegie Mellon University and Columbia
University, as well as the Santa Fe Institute. He was the chair of
the Computer Science Department at CMU, where he oversaw the growth of
the Department into one of the top CS departments in the world. He
was also the founding chair of the Columbia CS Department, where he
held the Edwin Howard Armstrong Professorship.

The unifying theme behind Joe's research was the role that information
plays when solving a numerical problem. This eventually led to the
creation of a new area of research, information-based complexity
theory, which studies the computational complexity of problems for
which the available information does not uniquely identify the problem
being solved.

Joe was the founding editor-in-chief of the Journal of Complexity, as
well as the founder of the Computer Science and Technology Board of
the National Research Council.

He was the author of over 120 papers, as well as the author or editor
of ten monographs (one of which, I was privileged to be his
co-author). He was the recipient of numerous awards and honors.

A memorial service will be held Friday, September 4, 10:00 am, at the
United Church (Arroyo Chamiso and St. Michael’s Drive, 505.988.3295)
in Santa Fe.

Full obituaries may be found at
The latter has a place for visitors to leave comments.

His colleagues are in the process of planning a suitable memorial.

Subject: AccFFT: A New Parallel FFT Library

Accelerated FFT is a new parallel FFT library for CPU and GPU. It
supports multi dimensional decompositions for computing a distributed
FFT for these architectures. The library uses several novel schemes
that make it up to 4x faster compared to existing codes. Currently it
supports real-to-complex, complex-to-complex, and complex-to-real

AccFFT is scaled up to 131K cores of Titan supercomputer at ORNL, and
32K cores of Stampede supercomputer at TACC. The GPU version of the
code is scaled up to 4,096 K20 GPUs of Titan. The homepage of the
library is, where the source code and its
documentation can be downloaded. The documentation involves several
steps that explain how to run the code for different cases.

The library is open sourced under GNU GPL2.

Subject: New Book, Line Integral Methods for Conservative Problems

We are glad to announce the publication, by CRC, of our book "Line
Integral Methods for Conservative Problems", which concerns
energy-conserving Runge-Kutta methods based on the so called discrete
line integral approach. The book fully covers this topic in Geometric
Integration, along with a number of generalizations. Both the theory
and the actual implementation of the methods is explained in full
details, along with a number of applications. More informations on
the book can be found at the web-site of the publisher,

Complementary material and related Matlab software can be retrieved at
the book homepage,

Subject: PhD Positions, Mathematics, Univ of Cambridge

Applications are sought for the CCA PhD course in Mathematical
Analysis starting in October 2016.

We are looking for first-class applicants who are either doing (or
have completed) a Masters-level course in mathematics or a four-year
degree course in a mathematical subject, and who ideally have some
prior experience of studying mathematical analysis.

The Cambridge Centre for Analysis is a Centre for Doctoral Training
based at the University of Cambridge, funded by the UK Engineering and
Physical Sciences Research Council (EPSRC). The Centre offers a unique
four-year PhD programme spanning pure, stochastic, computational and
applied analysis.

We believe that excellence in mathematical analysis requires a very
broad basis and our aim is to train students to be able and willing to
deploy a very wide range of techniques. This unique course has an
emphasis on team working and communication, alongside personal effort
and excellence, to foster a spirit of breadth and collaboration.

Subject: ACM TOMS Replicated Computational Results Initiative

The ACM Transactions on Mathematical Software (TOMS) has introduced a
new initiative to optionally review the computationals results of a
TOMS submission. This new effort is intended to assist in improving
the quality of scientific publication for TOMS and for the
computational science community as a whole. Manuscripts that
successfully complete the RCR Review process receive the RCR
designation when published.

The current issue of TOMS (Vol 41:3) contains my editorial describing
the RCR process, the first article published with the RCR Designation
("BLIS: A Framework for Rapidly Instantiating BLAS Functionality," by
Field Van Zee and Robert van de Geijn) and the RCR reviewer report
(authored by James M. Willenbring).

Details of Vol 41:3 are here:

Another purpose of the TOMS RCR initiative is to engage a portion of
the scientific community who are in fact experts in the use of math
software but are not typically involved in the publication process.
The expertise of these members is essential to making the RCR process
work well.

If you are interested in participating in this initiative, either as
an author or reviewer, please contact me.

Details of the TOMS RCR Initiative are available at
