The Aggregate refers to a collection of researchers and the technologies that they use to make the components of a computing system work better together. Since before our first Linux PC work in the PAPERS project, we have been considering all aspects of Compilers, Hardware Architectures, and Operating Systems (KAOS) together, optimizing system performance rather than performance of the individual parts. The only aspect of our computer system designs that is set in stone is our name.
Although the aggregate.org consortium has participants at various institutions, since 1999 it has been based in the Department of Electrical and Computer Engineering at the University of Kentucky, in Lexington, KY.
February 23, 2008 Aggregate.Org will participate in the Engineer's Day Open House at the University of Kentucky; there will be many activities, not just Aggregate.Org -- it's a neat way to spend a Saturday morning, and it's free
November 12-15, 2007 Aggregate.Org will have a major research exhibit at SC07; stop by and visit us!
September 14, 2007 The talk Big Ideas About Control Of Tiny Devices was given in the UK ECE seminar. This is a good overview of the nanocontroller work.
July 18, 2007 Senscape.Org, our new WWW site about integrated presentation of multidimensional sensor data, is now active.
June 6, 2007 International Science Grid This Week is running a feature story on our work on AVA, titled Working The Camera: Real-Time Grid-Powered Surveillance.
May 24, 2007 AIK, the Assembler Interpreter from Kentucky, is now available to external users. AIK makes it very easy to build assemblers, facilitating experiments that require creating or modifying an instruction set architecture.
March 2007 Computer Architecture Letters has accepted our paper Low-Cost Microarchitecture Support for Improved Floating-Point Accuracy for publication in the March 2007 issue. The paper describes simple hardware extensions that will speedup native-pair computations with less hardware complexity than a wider floating-point unit.
February 24, 2007 Engineer's Day Open House in the Department of Electrical and Computer Engineering at the University of Kentucky. Come see lots of cool stuff, including various research labs. We're also giving away a variety of little goodies....
January 12, 2007 Our paper overviewing the Cluster Design Rules (CDR), A Web-Based Tool for Optimized Cluster Design is posted at Cluster Monkey. (As of January 17, 2007, the Inquirer noticed.)
November 13-16, 2006 Aggregate.Org/University of Kentucky Research Exhibit, booth 232, at IEEE/ACM SC2006 in Tampa, FL. Stop by for the latest advances in GPGPU, the CDR, etc. In our booth (#232), two cameras captured fisheye images that you can view: a DLink DCS 900 with a peephole lens and an Olympus D340R. Now that the show is over, a summary of our exhibit is posted.
May 29, 2006 Prof. Dieter will be presenting Floating-Point Computation with Just Enough Accuracy at ICCS 2006. This is just a small part of our ongoing work involving Numerical Precision, Accuracy, and Range, especially for GPUs and other specialized processors.
May 3, 2006: A new tool called NetWires is now available to create graphical renderings of a wide range of types of interconnection networks, from direct connections to FNNs of Fat Trees.
April 10, 2006: Our new section on Digital Imaging Technologies is now open, with new material on Fisheye Digital Imaging For Under Twenty Dollars and a variety of other goodies.
This site, and the research described, includes work created by researchers at a number of institutions, but the lead research group is KAOS in the Electrical and Computer Engineering Department of the University of Kentucky in Lexington, KY. The primary contact people are:
Hank Dietz, Professor
and Hardymon Chair in Networking, created KAOS out of the
relatively well-ordered PAPERS Group that he founded
in 1994 at Purdue
University.
Bill
Dieter, Assistant Professor, lends some
stability to KAOS with his work on checkpointing and seems to know
how to fix a lot of the research that's slightly broken.

The
only thing set in stone is our name.
