The objective of IMPACT (Illinois Microarchitecture Project using Algorithms and Compiler Technology) is to provide critical research, architecture innovation, and algorithm and compiler prototypes for heterogeneous parallel architectures. We achieve portable performance and energy efficiency for emerging real-world applications by developing novel hardware, compiler, and algorithmic solutions.

Mert Hidayetoglu Selected as CSE Fellow (May 9, 2017)

This year 12 CSE faculty members, representing a broad spectrum of research interests, evaluated 39 CSE Fellow proposals. The proposed research must be interdisciplinary and computationally oriented. In the end, 8 proposals were selected for funding for the 2017-18 school year. CSE Fellows will present their research results at the annual CSE Symposium at the end of the school year.

Abdul Dakkak Presents at GTC 2017 (May 8, 2017)

A major component of many advanced programming courses is an open-ended "end-of-term project" assignment. Delivering and evaluating open-ended parallel programming projects for hundreds or thousands of students brings a need for broad system reconfigurability coupled with challenges of testing and development uniformity, access to esoteric hardware and programming environments, scalability, and security. We present RAI, a secure and extensible system for delivering open-ended programming assignments configured with access to different hardware and software requirements. We describe how the system was used to deliver a programming-competition-style final project in an introductory GPU programming course at the University of Illinois Urbana-Champaign. Abdul Dakkak, Carl Pearson, and Cheng LI authored the paper.

Carl Pearson Receives the Mavis Future Facultry Fellowship (MF3)

The Mavis Future Faculty Fellows (MF3) Academy in the College of Engineering was developed to facilitate the training of the next generation of great engineering professors. Engineering at Illinois is internationally recognized for the impact of our research and the strength of our graduate education. The doctoral programs that produce this reputation are primarily research-focused and may not provide students interested in academic careers with the opportunity to gain the knowledge of how to become a highly productive faculty member. To help address this issue, the Office of Engineering Graduate, Professional and Online Programs facilitates the MF3 Academy where fellows participate in a series of workshops, seminars, and activities that cover various aspects of an academic career.

Izzat El Hajj Receives Dan Vivoli Endowed Fellowship

This fellowship is given to students interested in the use of a Graphics Processing Unit (GPU) in parallel computing, the use of a GPU in solving high performance computing problems, and the development of applications for the GPU. Previous IMPACT recipients include Li-Wen Chang, Xiao-Long Wu, and John Stratton.

Mert Hidayetoglu receives the Professor Kung Chie Yeh Endowed Fellowship.

This $5,000 fellowship was established in memory of Professor Kung Chie Yeh, who devoted his career to teaching and research in wave propagation and upper atmospheric physics and morphology. Recipients must be conducting research in wave propagation and upper atmospheric physics.

Now Available: Programming Massively Parallel Processors 3rd Edition

The much anticipated 3rd edition of Programming Massively Parallel Processors A Hands-on Approach by David Kirk and Wen-mei Hwu is now available through all major book sellers including and Barnes & Noble. Broadly speaking, there three major improvements in the third edition while preserving the most valued features of the first two editions. The improvements are (1) adding new Chapters 9 (histogram), 11 (merge sort), and 12 (graph search) that introduce frequently used parallel algorithm patterns, (2) adding new Chapter 16 on deep learning as an application case study, and (3) adding a chapter to clarify the evolution of advanced features of CUDA.  These additions are designed to further enrich the learning experience of our readers. The book is used by more than 100 institutions worldwide for teaching applied parallel programming using GPUs.

Innovative Applications and Technology Pivots - A Perfect Storm in Computing

Since early 2000, we have been experiencing two very important developments in computing: a tremendous amount of resources have been invested into innovative applications and industry has been taking a technological path where application performance and power efficiency vary by more than two orders of magnitude depending on their parallelism, heterogeneity, and locality. In this talk, Dr. Hwu presents some research opportunities and challenges that are brought about by this perfect storm.
