@ACIS: The newsletter of the ACIS Lab Summer 2009

A Message from the Director
Dear Friends of the ACIS lab,
Thanks to the continued support of many of you, the ACIS lab continues to thrive as a place
where outstanding researchers work with state-of-the-art equipment to advance information-
.L processing science and technology. In this issue we share with you news about the most impor-
tant assets of the ACIS lab: people and infrastructure. Despite the lab's young age, ACIS folk are
making ACIS well known nationally and internationally, at major technical conferences and in
industry. ACIS alumni are now working at, among others, Amazon, Florida International Univer-
sity, Intel, IBM, Microsoft and VMWare. I expect this trend to grow as our programs develop and
more students join the lab and graduate. ACIS faculty continue to be successful in securing competitive funding
for research projects and the infrastructure needed for their execution. This issue mentions some of these projects
which promise to further position ACIS as a unique laboratory in the world for research on virtualization, cloud and
distributed computing, computer architecture and autonomic computing. You are welcome to contact us to learn
more about ACIS activities and I invite you to come, visit and even spend time working with us ACIS has become
an exciting place to learn, do research, make friends and enjoy turning novel ideas into functioning systems. You
can reach me at fortes@ufl.edu.

Sincerely yours,
Jose A. B. Fortes (on behalf of ACIS lab members)

Infrastructure Expansion Enables Cutting-edge Research

ACIS is renewing and considerably extending its com-
putational resources-within the lab and across mul-
tiple institutions-with newly funded and continuing
equipment projects. Here is an overview of what has
taken place this year:
Atanasoff: Our IBM/SP2 distributed memory parallel
computer was decommissioned, after providing years'
worth of CPU cycles to researchers in ACIS, the QTP
(Quantum Theory Project) group and other ACIS col-
laborators. As usual in the computing field, newer and
faster machines become available with every year that
goes by. As we disassembled Atanasoff (see pictures),
we made room and power in our data center available
for our new systems.
NSF MRI: The shared-memory cluster funded by the
ongoing Major Research Infrastructure (MRI) project
"Acquisition of Instrumentation for Coupled Experi-
mental-Computational Neuroscience and Biology Re-
search" is now our most powerful computing system.
It is a 32-CPU (128-core) IBM eServer 1350 cluster or-
ganized as two 64-core, 512GB NUMA systems. Given
the new cluster's large number of cores and memory
capacity, it was a bit challenging to virtualize, but now
it is running Xen justfine-kudosto MaurfcioTsugawa,
a senior ACIS student researching virtual network ar-

Atanasoff, a supercomputing resource that served
the ACIS Lab for many years, dismantled and
being removed from the ACIS data center
NSF CRI Archer: Another ongoing infrastructure proj-
ect is funded by the NSF Computing Research In-
frastructure (CRI) project entitled "Archer: Seeding a
Community-based Computing Infrastructure for Com-
puter Architecture Research and Education."While the
equipment will not arrive at the ACIS Lab until 2010,
the distributed system is up and running with clusters
at Florida State University, Northeastern University and
the University of Texas at Austin, with another cluster

at the University of Minnesota to come online in fall
2009. ACIS student David Wolinsky provided remote
configuration and management for the active clusters.
More information on the Archer project is available at
NSF CRI Autonomic Testbed: A new project funded by
the CRI program, slated to start in the fall of 2009, "An
Instrumented Datacenter Infrastructure for Research
on Cross-Layer Autonomics" is a collaboration among
the three university sites of the Center for Autonomic
Computing (UF, Rutgers University and the University
of Arizona). It will deploy a distributed set of instru-
mented clusters that will enable research on cross-layer
autonomic computing-connecting services with vir-
tualization and platform architecture in complex dis-
tributed systems-on a realistic data center testbed.
NSF CRI DiRT: Another new project also funded by the
CRI program, the "Distributed Research Testbed (DiRT)"
creates a testbed across five U.S. universities (the Uni-
versity of Mississippi, Notre Dame, University of Hawaii,
University of Chicago, and UF). The testbed consists of
cluster and storage nodes that will provide research-
ers with access to a heterogeneous, geographically
distributed set of resources with flexibility in the con-
figuration of virtualized and data-intensive wide-area
Amazon EC2: In addition to physical local resources, we
have obtained access to the Elastic Cloud (EC2) infra-
structure through an Amazon Web Service grant. The
resource credits will be used for research of systems "at
scale," giving us the flexibility of dynamically bringing
up and down pools of hundreds of virtual machines on
the distributed data centers hosted by Amazon.

Dr. Figueiredo presents at ICAC'09. Dr. Figueiredo co-
chaired a panel at the 6th International Conference on
Autonomic Computing (ICAC '09), held in Barcelona,
Spain in June. The panel discussion, entitled "Green
Clouds: Power Consumption as a First Order Criterion?"
was concerned with the environmental impact of pow-
er consumption in large-scale data centers. The panel
discussion, held on June 17, was co-chaired by Karsten
Schwan of the Georgia Institute of Technology.

Yonggang Liu and Priya Bhat join ACIS Lab. Two grad-
uate students have joined the ACIS Lab since our last
newsletter. Yonggang Liu, a graduate of Beihang Uni-
versity in China, is doing research with Dr. Figueiredo
on the IPOP project (for more information on hte IPOP
project, visit IPOP on the Web at http://www.grid-appli-
ance.org/wiki/index.php/IPOP). Priya Bhat is the recipi-
ent of a University of Florida Alumni Graduate award
for a four-year term and is currently studying computer
architecture, concurrent and distributed computing,
virtual machines, machine learning and pattern recog-
nition, and real-time applications under the direction
of Dr. Fortes. Welcome, Yonggang and Priya!
Linton Abraham and Jonathan Wyers visit for the
summer. Linton Abraham is visiting the ACIS Lab for
the summer to participate in the IPOP project. Linton
is currently an undergraduate student at Clemson Uni-
versity and is conducting research under the direction
of Dr. Sebastien Goasguen. Jonathan is a high school
student from Potomac Falls High School in Loudoun
County, VA, and was placed with the lab through the
University of Florida's Student Science Training Pro-
gram (SSTP). During his stay at ACIS, Jonathan will be
working with Dr. Figueiredo on monitoring and visual-
ization of data from PlanetLab.
Casey, Vineet and Mauricio defend PhD theses. Casey
Jeffery and Vineet Chadha defended their theses this
year. Casey Jeffery was advised by Dr. Figueiredo on a
project entitled, "Hypervisor-based Fault Tolerance in
Many-core Computing Platforms." For his dissertaion,
Casey developed an application that uses idle resourc-
es in distributed computing systems to provide dy-
namic fault tolerance that compensates for failures on
the single-transistor level. Vineet Chadha, also advised
by Dr. Figueiredo, focused his thesis research on input/
output (I/O) workloads in data centers. He defended his
thesis on October 13, 2008. Finally, Mauricio Tsugawa,
a student of Dr. Fortes, became the most recent ACIS
PhD graduate when he defended his thesis on virtual
networking on July 10. Congratulations to Dr. Jeffery,
Dr. Chadha, and Dr. Tsugawa!
Dr. Li receives NSF Career Award. Dr.Tao Li of ACIS Lab
has been awarded a National Science Foundation CA-
REER grant. As stated on the NSF web site, the CAREER
award recognizes young faculty "who exemplify the
role of teacher-scholars through outstanding research,
excellent education and the integration of education
and research within the context of the mission of their
organizations." Congratulations, Dr. Li!
