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.

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.

Wen-Mei Speaks at SuperComputing 2016

What a great time to be a student in computing!

Wen-Mei gave the Education/Career Keynote at SuperComputing 2016 in Salt Lake City.

"Programming Massively Parallel Processors" Text and GPU Teaching Kit: New 3rd Edition

Wen-Mei gave two talks Introducing the 3rd Edition of "Programming Massively Parallel Processors a Hands-on Approach". This new edition is the result of a collaboration between GPU computing experts and covers the CUDA computing platform, parallel patterns, case studies and other programming models. Brand new chapters cover Deep Learning, graph search, sparse matrix computation, histogram and merge sort.

The tightly-coupled GPU Teaching Kit contains everything needed to teach university courses and labs with GPUs.
