This is the home page for our 24th major research
exhibit at the IEEE/ACM Supercomputing conference. The exhibit
is again under the slightly changed title University of
Kentucky / Aggregate.Org, reflecting the fact
that it is now officially led by the Center for Computational
Sciences. Of course, 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 still has
a large fraction of the materials in the booth. We are
booth #943, a 10x20 booth; we're sort-of in the
middle of the exhibit hall.
Our 24th 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 various computational photography things.
We kept handouts to just six topics:
How Low Can You Go? -- supercomputing
has long been about maximizing parallelism. Well, that's not the big problem
anymore. Now, it's all about power. We have been developing compiler
technology that is strong enough to do gate-level optimization of whole
programs, thus minimizing the number of active gates needed to accomplish
Cameras As Computing Systems -- this
overviews some of the multi-cameras and other research we've been doing
treating cameras as computing systems. After all, our approach is really
about looking at all aspects of a computing system and improving how
the hardware and software components interact in order to get higher
performance and new capabilities... not shocking we do that for computer
systems that look like cameras....
TIK: Temporal Imaging from Kentucky -- for
years we've been working on Time Domain Continuous Imaging (TDCI), which
replaces the concept of am imager capturing frames with capture of continuous
waveforms for pixel light level over time. With TIK, you can do this using
conventional still and video cameras!
Making Time Tooling Around --
Perhaps you're wondering what the computer engineering research group that
created PCCTS/Antlr, SWAR (SIMD Within A Register), the first Linux PC cluster
supercomputer, FNNs (Flat Neighborhood Networks), and MOG (MIMD On GPU) is
doing playing with machine tools? We began using these machines to make camera
parts for our computational photography research, but we're really about
making the hardware and systems software components of a computing system work
better together, and those machine tools are computer systems. Never forget
that you can use your tools to make better tools....
Networks -- an overview of the many tools and technologies
we have developed to improve computer networks, especially those
within parallel supercomputers. AFNs, FNNs, KNITT, Netwires,
and NodeScape are all briefly described. (Just two years ago,
we learned that Google has been using our FNN work as the basis
for designing much of their network infrastructure.)
A Maze of Twisty Little Passages --
an update to MOG (MIMD on GPU). The MOG core is becoming close to
production quality and there are now several system calls implemented
(the GPU code can now perform host system calls). We didn't bring
the big wooden maze, but did bring a couple of small plastic ones that
made the MIMD-can-run-efficiently-on-SIMD point as well as their
giant wooden sibling used to.
Here's what our booth looks like this year:
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, but we didn't want to risk bringing our MakerGear M2
as airline checked baggage. Thus, we bought and brought a $400
Wanhao I3. Really quite a nice machine... more finished than the M2,
and capable of comprable print quality, but at much slower
print speeds. We are using it to 3D-print working mechanical
NOR gates, which we are handing out at SC17:
The GateRodders 3D-printed
mechanical NOR gates that we printed and gave away at SC17 now
have their design posted as Thing
Here's the Aggregate.Org contingent in our research exhibit.
You can see the whole exhibit pretty well here; there were four
TVs running presentations in the corners, four back-to-back
pull-up posters defining the back of the booth, and two tables
in the front. The left one held handouts, the right one had our
3D printer (the Wanhao i3) and two laptops for running the
printer and giving demos. From left to right, that's Jong Wu,
Paul Eberhart, Clark Demaree, Randy Fisher, and Hank Dietz
Here's proof I occassionally even feed my people....
Here's a photo with all the folks from the University of Kentucky.
Are website updates ever done?
The only thing set in stone is our name.
