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 http://www.cs.columbia.edu/2015/joseph-traub-in-memoriam http://www.santafe.edu/news/item/in-memoriam-joseph-traub The latter has a place for visitors to leave comments. His colleagues are in the process of planning a suitable memorial. ------------------------------------------------------- From: Ding Rujuan [log in to unmask] Date: August 27, 2015 Subject: Feng Kang Prize Awarded The 11th Feng Kang Prize of Scientific Computing Announcement The 11th Feng Kang Prize of Scientific Computing has been honored to - Dr. Yuhong Dai, Academy of Mathematics and Systems Science, Chinese Academy of Sciences, China; - Dr. Weiqing Ren, National University of Singapore and Institute of High Performance Computing A*STAR, Singapore for their significant contributions in Nonlinear conjugate gradient methods, quasi-Newton methods and spectral gradient methods; and Numerical methods for the study of rare events, multiscale modeling and simulation, the moving contact line problem.

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 transforms. 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 http://accfft.org, 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. ------------------------------------------------------- From: Luigi Brugnano [log in to unmask] Date: August 26, 2015 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.

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: http://dl.acm.org/citation.cfm? id=2786970&picked=prox&cfid=539910145&cftoken=74800503 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.
