Research Exhibit

This is the home page for our 14th major research exhibit at the IEEE/ACM Supercomputing conference. The exhibit is again under the title Aggregate.Org / University of Kentucky, the informal research consortium led by our KAOS (Compilers, Hardware Architectures, and Operating Systems) group here at the University of Kentucky's Department of Electrical and Computer Engineering.

A time-lapse fisheye movie of our exhibit is available as a 28,451,014 byte MPG file. Camera trouble and a power failure caused most of Tuesday to not be recorded, but it is otherwise a fairly complete record of activity in our research exhibit during show hours.

Work Presented

The most obvious focus was a demonstration of the effectiveness of speculative precision. This was done using four "slot machines" like the one shown above. Here is a movie of one of the slots in action... summing a series of numbers in single, double, and arbitrary precision, and paying off when all three result in the same value to 5 decimal digits.

The very wide range of topics emphasized in our exhibit is summarized in the following white papers, which were distributed from our research exhibit, booth R3043, at SC07:

• The Loosest Slots In Reno
  (about the funny-looking "slot machines" in our exhibit - Numerical Precision, Accuracy, and Range)
• Horseshoes and Hand Grenades
  (about precision and accuracy - Numerical Precision, Accuracy, and Range)
• Come Together Right Now Over Me
  (about Aggregate Function Networks - Theory, Software, and Hardware)
• Cluster Design for the Lazy or Paranoid
  (about the Cluster Design Rule software tool - Cluster Design Rules)
• Flat Outperformance
  (about Flat Neighborhood Networks - NetWires)
• You Can't Always Get What You Want
  (about Line Associative Registers vs. conventional cache)
• Small Thinking
  (about Nanocontrollers - Kentucky Architecture, Nanoprocessors, & Nanocontrollers)
• Powerful Beyond Dissipation?
  (about predictive power management - Energy Management)
• See & Hear, Show & Tell
  (about digital imaging using light, sound, etc. - see Digital Imaging Technologies)
• SWARC: SIMD Within A Register C Module Language and Compiler
  (a hold over from last year... from SWAR to GPUs - SWAR: SIMD Within A Register)

Physical Exhibit Layout

Much like last year, our research exhibit was positioned at the far end of the aisle -- in this case, the one that runs diagonally through the southernmost room in the exhibit hall.

A DLink DCS 900 with a peephole lens, mounted on the slot machine in the rear left corner of the booth; images are archived here. It was from these images that the exhibit time-lapse movie was constructed.

The only thing set in stone is our name.
