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.

Pebble Of The Day/Week/Whenever

February 20, 2010 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 14-20, 2009 Aggregate.Org will have a major research exhibit at SC09. We will be showing a lot of things, many of which involve MOG (MIMD On GPU) technologies.

October 8, 2009 We presented two papers at the 22nd International Workshop on Languages and Compilers for Parallel Computing: Hardware Support for OpenMP Collective Operations and MIMD Interpretation On A GPU.

September 26, 2009 We've posted a couple of new documents about a bit of technology recycling for digital imaging: Old Film Camera Lenses On New Digital Cameras and Big Old Camera, Tiny New Sensor.

September 4, 2009: Diego Rivera successfully defended his MS thesis on Reduction Operations and Synchronization Mechanisms on NVIDIA GPUs.

July 24, 2009: Dalton Young successfully defended his MS thesis on an implementation of MPI running native in the CUDA environment on NVIDIA GPUs.

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.
