IEEE/ACM SC14 Aggregate.Org

This is the home page for our 21st 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 #3413, on the far right as you enter the hall.

Our 21st Exhibit

As usual, our research exhibit this year will be showing a lot of different things we have developed or are developing... ranging from supercomputer architecture to 3D printing technology and a new model for imaging sensors. Here's the booth overview on the big screen we used as signage, slide show, and two live camera views:


The primary new stuff was two major updates:

Here's what that part of the booth looked like:

3D Printer

3D printing plays a major role in the computational photography work we are doing (for 3D printing custom camera parts), and 3D printing is cool, so we brought our MakerGear M2 to the booth as well. Here it is printing simple UK "3D print" keychains 8 at a time:

There were several other 3D printers running on the show floor. Indiana University had a Lulzbot Taz printing a captured gear thing... well, at least trying to with most parts failing. There were also a couple of MakerBots, one in particular trying to print things like a little red dragon which had horrifically ill-designed overhangs that came out as messy as one might suspect. In fact, our M2 was the only printer making things designed by the folks operating the printer. The M2 also was printing most of what we did at 140mm/s at 0.25mm extrusion, while the other printers were running as slow as a ludicrous 10mm/s in a (failed) attempt to get comparable print quality. Live video from the blue webcam on the printer was also displayed on the big screen, really showing-off the M2 print speed.

We didn't ask MakerGear for anything, nor did they give us anything, but they sure got some great PR out of our booth!

Something Old

The big surprise in our booth was the 20-year-old TTL_PAPERS microcluster. We celebrated 20 years of Linux cluster computing at SC13. However, with all the fuss about 20 years of Beowulf, we this year decided it might be fun to revive this old cluster, which in 1995 became the first portable (luggable) Linux cluster. After replacing CMOS back-up batteries, only one of the four Compaq Aero laptops didn't boot (bad disk). We recompiled the ancient software for 3 processors and everything worked!

It was actually running the same demo it did at SC95, playing multi-voice music by toggling the PC speakers, randomizing which machine played each note and syncing at every note using the TTL_PAPERS hardware with 3us latency. Three of us who built the first Linux PC cluster in 1994, and this system ins 1995, were at SC14. Here we are, left to right, Randy Fisher, Hank Dietz, and Tim Mattox:

Timelapse Video

Here's our traditional fisheye timelapse video of the exhibit. It's missing some stuff because, as always, relying on wireless at SC isn't really a good idea....

The Aggregate. The only thing set in stone is our name.
