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. If you're at UK, feel free to join the "KAOS" listserve.
May 2012 After many years there, we are now moving out of 301 and 302 DVT. It hasn't been a well-utilized space since we moved into Marksbury, so the primary effect is that we no longer have to explain where DVT is.... ;) Secondarily, that's why you no longer see it on our sensors page.
April 17, 2012 Hank Dietz will be presenting a free and open seminar on NodeScape: Supercomputer Status at a Glance in 108 Marksbury from 3PM to 4PM. NodeScape is the thing that generates these displays.
April 2, 2012 The University of Kentucky's basketball team defeated Kansas 67:59 for our 8th NCAA national title. Congratulations to our team and Coach Calipari for demonstrating once again how talent, work, and especially teamwork make Kentucky better and often best. Sometimes, people don't see Kentucky, but through this win more people will See Blue.
March 21, 2012 Matthew Sparks will be presenting a free and open seminar on Line Associative Register Architecture in 108 Marksbury from Noon to 1PM.
March 19, 2012 Can you use some of our free compute cycles? Yes, UKAN! We are making some of the "uncommitted KAOS accessible nodes" freely available to collaborators and worthy projects... see UKAN for details....
March 7, 2012 DeOrbIt WWW tool is posted. We developed this free tool to make the dreaded Fujifilm X10 "white orbs" look more natural. We plan to release a full C source code version into the public domain as soon as tuning is done and a research paper on the method completed, but this WWW form version is now open for public testing.
February 25, 2012 Engineers Day Open House at the University of Kentucky. Various activities will be held and many labs will be open. Come visit us in 672 F. Paul Anderson Tower, our secondary supercomputer machine room, from 9AM-1PM. February 23, Lex18's Lee Cruise did a segment on us in the Marksbury Building, but due to logistics issues, the Marksbury Building will not be open February 25. Tours of Marksbury facilities can be scheduled at other times.
January 26, 2012 Prof. Dietz will be presented Reprocessing Anaglyph Images, paper number 8290-27, at the IS&T/SPIE Electronic Imaging conference in San Francisco. Here are the slides and paper preprint.
January 25, 2012 Frank Roberts will be presenting a free and open seminar on KOAPing With The OpenCL API in 108 Marksbury from 11AM to noon.
November 28, 2011 KOAP: Kentucky OpenCL Application Preprocessor is now available as an "alpha quality" full source release.
November 12-17, 2011 Aggregate.Org will have a major research exhibit at SC11. We will be showing a lot of things, including MOG (MIMD On GPU), NodeScape, and KNITT (Kentucky Network ImplementationTopology Tool).
November 11, 2011 Prof. Dietz gave two talks at Microsoft Research in Redmond, WA. Both talks are now available online: The Benefits of Being Out Of Focus: Making the Most of Lens PSF and MIMD on GPU.
September 7, 2011 Meeting for UK grad & undergrad students interested in learning about our research group. Like the hardcopy announcement (PDF) says, we'll have pizza in 108 Marksbury at 1PM.
May 9, 2011 Our new machine room in 108A Marksbury is now reasonably operational... and we have a new tool, nodescape, that helps monitor everything. Here is the current status of the equipment in 108A Marksbury.
March 14-18, 2011 During UK's Spring Break, we are starting to power-up our new machine room, etc., in the new Davis Marksbury Building. Prof. Dietz now has his office in room 203, and the new lab and machine room are room 108 and 108A. Yes, we still have our old machine room in 672 FPAT... and both are quite full. ;-)
February 26, 2011 Aggregate.Org participated in the Engineer's Day Open House at the University of Kentucky; there were many activities, not just Aggregate.Org -- it's a neat way to spend a Saturday morning, and it's free.
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. Aggregate.Org is led by Professor and Hardymon Chair in Networking, Hank Dietz, who created KAOS out of the relatively well-ordered PAPERS Group that he founded in 1994 at Purdue University.
