Subject: Roland Sweet, March 14, 1940---April 15, 2019

Roland Sweet passed away April 15, 2019.

Roland earned his Ph. D. in Computer Science at Purdue University in
1967. He was an Assistant Professor at Cornell University, working
summers at Argonne National Laboratory and Marathon Oil Company.  He
joined the Department of Mathematics at the University of Colorado in
1970, teaching at the Denver Campus and consulting at the National
Center for Atmospheric Research (NCAR). He received tenure in 1974.
In 1980, Roland joined the National Bureau of Standards (NBS now NIST)
in Gaithersburg, Maryland. Two years later, he transferred to the NBS
laboratory in Boulder, Colorado. In 1985, he joined the Department of
Mathematics at the University of Colorado, Denver, becoming the
Director of the Computational Mathematics Group in 1988.

Along with Paul Swarztrauber, Roland was one of the early pioneers of
fast direct Poisson solvers using the methods of Fourier analysis and
cyclic reduction (FACR), which resulted in the widely used software
package FISHPACK for sequential, vector, and parallel processors.

Roland retired for the first time in 1996 and spent two years sailing
around the Caribbean with his wife, Linda Lindgren. After that
adventure, he worked in Seattle for Lizard Tech, developing image
processing software, and in McKinney, Texas, for several companies. He
retired for the last time in 2008 and spent his final years in
Boulder, where he became deeply involved in the Boulder Homeless
Shelter and Earth's Table Community Garden.

Roland was a good friend and colleague. He had an easy smile, quick
wit, and a great sense humor. We will all miss him greatly.

Subject: Quasi-Variational Inequalities, Germany, Sep 2019

Quasi-variational inequalities (QVIs) form a notoriously difficult
class of problems which differ from standard variational inequalities
since its feasible set also depends on the decision variable. Besides
this fact, the QVI has become a standard tool for the modeling of
various equilibrium-type scenarios in the natural sciences and
includes, in particular, the generalized Nash equilibrium problem
(GNEP). QVIs therefore have a wide range of applications in game
theory, continuum mechanics, economics, transportation etc.

The lectures will be given by
- Jong-Shi Pang (University of Southern California, USA):
  Generalized Nash-Equilibrium Problems in Finite Dimensions
- Carlos N. Rautenberg (Humboldt Universitaet zu Berlin, Germany):
  Introduction to Quasi-Variational Inequalities in Hilbert Spaces
- Hasnaa Zidani (ENSTA ParisTech, France):
  Optimal Control and Hamilton-Jacobi-Bellman Equations

Subject: Postdoc Position, Reconfigurable Computing

The Center for Research in Mathematical Sciences Applied to Industry
(CEPID-CeMEAI) at University of Sao Paulo opens a post-doctoral
research position in Reconfigurable Computing. The selected candidate
will work at Institute of Mathematical and Computer Sciences of
University of Sao Paulo in Sao Carlos/SP, Brazil. Sao Paulo Research
Foundation provides the financial support with a monthly salary of
R$7,373.10. Financial support can also be provided to cover
transportation expenses as to the move to Sao Carlos - Brazil. An
extra grant is also provided to cover participation in highly relevant
conferences and workshops, as well as research trips (limited to 15%
of the annual amount of the fellowship). The position is for one year.

Project: Development of an FPGA-orientated hardware system for real
time financial market access.

Supervisor: Dr. Alexandre A. C. Delbem

Description: The financial market has employed real time computing
systems to accelerate trading operations known as HFT (High Frequency
Trading) systems. One of the major challenges of HFT systems is to
guarantee predictability of the system execution time and low latency
for the system response. Such features are fundamental to determine
its success. Then use of reconfigurable hardware for data processing
at package level is the state of the art for this type of
systems. This approach eliminates the various layers of software that
exists in traditional systems and allows both data preprocessing and
decision-making algorithms to be implemented directly in hardware
circuits using dedicated communication channels. This project aims to
construct such HFT system based on FPGA device, including resources to
access the financial market directly via FIX/FAST protocol and to
interface with software processors for hardware configuration and
monitoring. The research will be led jointly by Dr. Vanderlei Bonato.
Requirements: Applicants should have PhD in Computer Science or
related fields with experience in hardware development for FPGAs,
hardware description languages, high level synthesis languages, design
space exploration, and modeling and solving optimization problems. It
is also desirable to have experience in developing interfaces for
Gigabit Ethernet devices and DDR3 and DDR4 memories. The applicant
must have got their PhD in the last 5 years.
Application: Please send your application until June 4, 2019 to: Dr.
Vanderlei Bonato ( [log in to unmask] ) indicating 'CEPID Postdoc - HFT'
in the subject line. Applications should include curriculum vitae,
statement of research interests and two contact information for
recommendation purpose (only PDF files).
