This is the home page for our 20th 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. We are booth #629, near the left side of the hall and about 2/3 of the way back from the entrances (as seen in the exhibit hall floorplan).

Our 20th Exhibit

As usual, our research exhibit this year will be showing a lot of different things we have developed or are developing, but this year one of our two slideshows is a 20-year history overview showing some of our key accomplishments, from the first Linux clusters and PAPERS (Purdue's Adapter for Parallel Execution and Rapid Synchronization) network hardware to MOG (MIMD On GPU) and beyond. We actually had the original PAPERS unit on display, and it attracted a surprising level of attention... it's rather surprizing that the operations that it did in 3us back in 1994 still take longer than that using the latest, fastest, network hardware... at least it is no longer 5 orders of magnitude faster than standard network hardware.

New Work Presented

• Time Domain Continuous Imaging
  (the big new thing this year: millions of PEs inside an imaging sensor)
• 20 Years of AGGREGATE.ORG SC Exhibits
  (our history summary)
• A Maze of Twisty Little Passages
  (an update on MIMD On GPU -- MOG -- return of the wooden maze)
• Adventures in KNITTing
  (about optimizing physical layout of cluster supercomputers)
• Flat Outperformance
  (update on the evolution of FFNNs)
• Make Things Better
  (about gamake, a tool using GA technology to optimize anything built by a makefile)
• One Chip, Millions of Nanocontrollers
  (about Nanocontrollers - Kentucky Architecture, Nanoprocessors, & Nanocontrollers)
• Tasseography, Scrying & Cluster Status
  (about nodescape and how it makes cluster status easy to see)
• You Can't Always Get What You Want
  (about Line Associative Registers vs. conventional cache)

3D-Printed Stuff

Well, we have a 3D printer, so of course there was 3D-printed stuff in our exhibit this year. In general, see our MAKE page for info about what we are doing with 3D printing technologies. The 3D-printed stuff in our exhibit included:

20th Year Refrigerator Magnet, http://www.thingiverse.com/thing:189344

A giveaway made for our SC13 exhibit. This commemorates our 20th year as an SC research exhibit and the upcoming 20th anniversary of our building the world's first Linux PC cluster supercomputer in Feb. 1994.

Dovetail Puzzle Keychain, http://www.thingiverse.com/thing:189221

A giveaway made for our SC13 exhibit. This 3-piece keychain dovetail puzzle shows the basic principle behind SWAR and LAR technologies: carving a fixed-size data path into various size fields that are operated upon in parallel.

3D-Printed Page Holder, http://www.thingiverse.com/thing:189007

Minor tweaks on an existing design for a page holder. We did this to hold handouts for display at SC13; it worked very well.

IEEE SoutheastCon 2014 Keychain, http://www.thingiverse.com/thing:189455

Made as a "save the date" reminder and originally distributed at IEEE SoutheastCon 2013 to all paper authors, we've finally posted the design on Thingiverse. To keep print time down, it's actually a bit thin. It isn't thin enough to cause any functional problems as a keychain, but you might want to increase the thickness a little for a more robust-feeling print.

Live Camera

Well, not so live.... We depend on SC13's wireless network to do live things and, well, it hasn't been reliable enough this year to be pushing much of anything back to our servers. That hasn't stopped us from capturing fisheye views of our booth with an old network camera.

The time-lapse movie will be posted here after we get home... sooner if wireless gives us a chance. Well, it's partly here: Monday time-lapse video

The only thing set in stone is our name.
