Gather around as I tell the tale of settlers of a distant
island called ‘Oahu nestled in the mysterious Polynesian island chain of
Hawai’i. It is a tale of danger, great courage and ultimately triumph…
The Landing
The Laboratory for Advanced Visualization and Applications (LAVA)
got its start at the beginning of 2014 by Dr. Jason Leigh who was also the
director of the Electronic Visualization Laboratory or EVL at the University of
Illinois at Chicago. The mission of LAVA is to conduct research and development
in big data visualization techniques, and to apply these techniques in cutting
edge domain science, engineering, and training applications. Its first
residence was within his office space at the Pacific Ocean Science and
Technology (POST) Building 309. Over there, the meeting space was setup with
two Seiki 50-inch 4K Ultra HD TVs connected to Samoa, a Dell Aurora-R4
outfitted with an i74960X CPU, 32 GB of RAM and a GeForce GTX 780.
Big monitors are nice, but by themselves require users to
directly connect to them. The extra work for cable organization and having the
correct adapters to allow user access generated a large setup time before a
meeting could be started and still caused downtime when switching between
presenters. To enhance the meeting discussions by reducing hardware setup, the
Scalable Amplified Group Environment (SAGE2) software was deployed to enable
not only a quicker, smoother transition between presenters, but an open
collaborative environment that could take advantage of both monitors at the
same time.
Immigration
While the space at POST was sufficient it couldnÕt fit more
than seven people comfortably. For spring 2015, Dr. Leigh was to host a class
and needed a room to accommodate more than 30 people at once. Thus the move to the
Kuykendall Building (KUY) began. Among the first issues to address was how to
display information that could be seen from the opposite of the room. It did
not come with whiteboards, projectors, or any of the usual infrastructure to
teach a class. The decision was made to forgo such equipment and build upon the
SAGE2 setup that was in POST. However the equipment brought over was no longer
sufficient. While great for a gathering of members around a table, miniscule in
the context of showing a room of students. Three new monitors were bought, LG
84-inch 4K Ultra HD 3D TVs. While initially there was worry about whether or
not the computer could run it, these fears were quickly put to rest. Only when
trying to stream more than four video sources at once was when lag became
noticeable.
Settlers of Keller
Keller was a larger space and the goal once again was to
improve upon the equipment setup. 18 Planar panels each driven by one computer.
However Samoa wasn’t strong enough. To take its place an Area-51 model, called Pele,
was ordered. A significant improvement over Samoa, one of the major hardware
improvements was the i7-5960X CPU and the two(SLI) GeForce 980 video cards.
However, between the the two 980’s there were only six ports available to drive
the 18 monitors. To get around this, the Planar controllers connected to the
Pele through three Matrox TripleHead2Go splitters to allow three planar panels
to receive input from one HDMI cable. The current setup recognizes three of the
planar panels as one monitor and they are arranged in the following format.
In addition to the visible hardware, SAGE2 relies heavily on
an infrastructure that supports streaming and powerful endpoints (GPU and
10Gbps networks). With the development of SAGE2 and lighter-weight technologies
(client-side rendering in browser, cloud, javascript), it was now possibility
to drive a large display wall with a single PC. Using Microsoft Windows allows
teachers to use the wall for various classes (SciVis, InfoVis, Gaming, Design,
etc) and in various configurations (SAGE2, Unity3D, presentations and web
pages).
Rations
Pele is an Alienware Area-51, classified on Dell’s store as a
gaming computer. The intention of using a gaming computer is that the usage
shows commonly available equipment is sufficient and specialized equipment is
not needed to operate a SAGE2 wall. Other non-visualization groups will be able
to easily order a machine of their own to mimic our setup without a significant
hassle over part lookup. Other great benefits include a reasonable price range,
reduced noise (compared to a server class computer), and the ability to
purchase hardware upgrades since the computer uses standardized parts. At the
time of writing Dell is already offering better hardware options than Pele is
outfitted with.
Pele’s major components:
CPU: Intel Core i7 5960X 3.00GHz 20MB
L3 Cache
RAM: 4 x 8GB DDR4-2133 1066MHz
Graphics: 2x (SLI) NVIDIA GeForce 980 4GB GDDR5
Primary Storage: SSD 512GB
NIC: Gigabit ethernet
The Planar wall is comprised of 46″ panels each with 1360×768
pixels. The panels themselves have controllers that fit into a server rack.
Pele, itself however is only outfitted with two video cards totaling 6 ports.
Matrox 1-to-3 extenders were necessary to connect up all 18 Planar panels. The
server rack was placed to the right of the panels with Pele on the bottom and
Planar controllers on the top.
A wired keyboard and mouse are impractical for usage due to
distance requirements. An all-in-one Logitech wireless keyboard is used.
In addition to the above equipment a Yamaha Digital Sound
Projector, which included a sub-woofer, is used for its low profile and decent
quality sound. The meeting area of the room occupies roughly half of the
50’x32′ room and even though the Yamaha is only one emission unit, it is still
able to throw directional sound around the meeting area.
For video conferences a Logitech ConferenceCam CC3000e
All-In-One bundle was setup. In terms of software, Google Hangouts was able to
make full use of the resolution offered by the camera. However to make use of
the higher resolution settings the camera offered, the network had to be
sufficiently robust otherwise everything started to lag. The base station had
decent noise cancelling built in, to date we have not had to adjust the settings.
The receiver seems to be able to detect normal talking voices with clarity up
to 20′. However to ensure each of the desks, including a lecturer_s podium had
sufficient audio pick up we decided to purchase 3 daisy-chainable Phoenix Audio
Smart Spider MT503 voice conferencing speaker-mics, and a Q3 Power Adaptor
(MT320). The MT320 enables power to be passed through the master unit to the
slave units through the daisy-chain Ethernet cable. This meant that each of the
slave MT503s could operate with merely the daisy chain cable and no additional
power supply- which helps reduce the number of cables in a conference room
setting.

The Kuykendall room used three LG 84-inch 4K Ultra HD TVs (Left).
The POST room used Seiki 50-inch 4K Ultra HD TVs (Right). Which unfortunately
have since been discontinued.
Samoa, the Dell Aurora used to drive the setup in Kuykendall
had the following specs:
CPU:
Intel Core i7-4960X CPU @ 3.60 GHz
RAM: 4 x 8GB DDR4-2133 1066MHz 19-15-15
Graphics: NVIDIA GeForce GTX 780
Primary Storage: HDD 512GB
NIC: Gigabit ethernet

overcome them? Stay tuned for future exciting Tales of the CyberCANOE.
