Title: A Sustainable Distributed Infrastructure for Supercomputing Applications
Abstract: Scientists' dream of accessing any supercomputer in the world (or in the
'Cloud') is currently coming true. Independently from time and space, they
are now able to perform even larger and more accurate scientific computer
simulations, at their finger tip.
Today, high-speed networks transport data at the speed of light,
middleware manages distributed computing resources in an intelligent
manner, user-friendly portal technology enable secure, seemless, and
remote access to resources, applications, and data, and sophisticated
numerical methods approximate the underlying mathematical equations (that
is: the fundamental laws of nature) in a highly accurate way. With the
convergence of these core technologies into a distributed, service
oriented architecture, we see the rise of large compute and data grids
currently being built and deployed by e-Infrastructure initiatives such as
DEISA, EGEE, NAREGI, TERAGRID, and others.
With the aid of one example, in this presentation, we will elaborate on
the Distributed European Infrastructure for Supercomputing Applications,
DEISA, which recently entered its second project phase. We will describe
the system architecture, the DEISA Common Production Environment, and the
main middleware components which enable remote and secure access to
scientific applications, data, and the supercomputers distributed all over
Europe. Finally, we will summarize main lessons learned and provide some
useful recommendations on how to build and operate a sustainable
e-Infrastructure which (amost) looks like a Cloud.
Bio: Wolfgang Gentzsch, is an Adjunct Professor of Computer Science at Duke

several Government funded projects, and he was the founder of software
companies Genias and Gridware. He has been consulting for the US, Germany,
Austria, Italy & Ireland Governments. He has also taught at Universities
in Chapel Hill, Duke, Raleigh, and Regensburg.
His main interests are in distributed computing for research and industry,
from a technology, strategy, and operations point of view. He received his
PhD from University Darmstadt, Germany in 1974.
Speaker: Manish Gupta
Title: A Parallel Web for the Masses
Abstract: In India and several other countries, the number of mobile phone subscribers far exceeds the number of personal computer users, and continues to grow at a much faster pace (it just crossed the 300 million mark in India). We will present Spoken Web, an attempt to create a new world wide web, accessible over the telephone network, for the masses in these countries. The Spoken Web is based on the concepts of Hyperspeech and Hyperspeech Transfer Protocol that allow creation of "VoiceSites" and traversal of "VoiceLinks". We describe a simple voice-driven application, which allows people, without any information technology background, to create, host, and access such VoiceSites, and traverse VoiceLinks, using a voice interface over the telephone. We present our experience from recent pilots, conducted together with Byrraju Foundation, in a few villages in Andhra Pradesh. These pilots demonstrate the ease with which a semi-literate and non-IT savvy population can create VoiceSites with locally relevant content, including schedule of education/training classes, agicultural information, and professional services, and their strong interest in accessing this information over the telephone network. We describe several outstanding challenges and opportunities in creating and using a Spoken Web for facilitating exchange of information and conducting business transactions.
Bio: Manish Gupta is the Associate Director at the IBM India Research
Laboratory. In various technical and senior management positions he has
held at IBM India and at the T. J. Watson Research Center, Manish has
led efforts to pursue challenging new missions at IBM India and has led
research on system software for the IBM Blue Gene supercomputer and
other Deep Computing platforms. Manish received a B. Tech. in Computer
Science from IIT Delhi in 1987, a Ph.D. from the University of Illinois
at Urbana-Champaign in 1992, and has worked with IBM since then. He has
co-authored over 70 papers in the areas of high performance compilers,
parallel computing, and Java Virtual Machine optimizations, and has
filed sixteen patents. Manish has received two Outstanding Technical
Achievement Awards and the Gerstner Team Award for Client Excellence at
IBM, and has been invited to give keynotes at several international
conferences and workshops.

Title: Utility-Oriented Cloud Computing: A Vision, Hype, and Reality
Abstract: Computing is being transformed to a model consisting of services that
are commoditised and delivered in a manner similar to utilities such as
water, electricity, gas, and telephony. In such a model, users access
services based on their requirements without regard to where the
services are hosted. Several computing paradigms have promised to
deliver this utility computing vision and they include Grid computing,
P2P computing, and more recently Cloud computing. The latter term
denotes the infrastructure as a “Cloud” from which businesses and users
are able to access applications from anywhere in the world on demand.
Hence, Cloud computing can be classed as a new paradigm for the dynamic
creation of next-generation Data Centers by assembling services of
networked Virtual Machines (VMs). Thus, the computing world is rapidly
transforming towards developing software for millions to consume as a
service rather than creating software for millions to run on their PCs.
To realize Cloud computing, vendors such as Amazon, HP, IBM, and
Sun are starting to create and deploy Clouds in various locations around
the world. In addition, companies with global operations require faster
response time, and thus save time by distributing workload requests to
multiple Clouds in various locations at the same time. This creates the
need for establishing a computing atmosphere for dynamically
interconnecting and provisioning Clouds from multiple domains within and
across enterprises. There are many challenges involved in creating such
Clouds and Cloud interconnections.
This keynote talk (1) presents the 21st century vision of
computing, (2) identifies various computing paradigms promising to
deliver the vision of computing utilities, (3) defines the architecture
for creating market-oriented Clouds and computing atmosphere by
leveraging technologies such as VMs, (4) provides thoughts on
market-based resource management strategies that encompass both
customer-driven service management and computational risk management to
sustain SLA-oriented resource allocation, (5) presents our current work
towards realising market-oriented resource allocation of Clouds by
leveraging the 3rd generation Aneka enterprise Grid technology, (6)
reveals our early thoughts on interconnecting Clouds for dynamically
creating an atmospheric computing environment along with pointers to
future community research, and (7) concludes with the need for
convergence of competing IT paradigms for delivering our 21st century
vision.
