studies. Not only did I acquire technical skills in the process, as I learned
new software tools and programming languages, but I also learned
how to effectively present your project in front of a large audience.
During my stay at the CUTE Center, there were numerous incidents
when I had to exhibit my projects in
public. Sometimes they were in the
form of group exhibitions where various lab members showcased their
projects; at other times there were
individual demos for media coverage. In short, working at CUTE Center was a stepping-stone for me, an
engineering student who aspires to
be a researcher. It gave me a glimpse
of what research is really like—
something very different from normal
Anshul Vikram Pandey studied electrical and electronics
engineering in India. He visited CU TE Center in 2011 as a
research intern and later completed his bachelor’s thesis
there. Currently, he is with the NUS-HCI Lab, Singapore,
working as a research assistant.

CERN is using GPGPU computing at the ATLAS project to filter
the large amounts of data generated by the experiment.
Computers are used to solve problems in numerous scientific fields
where tasks can range in complexity from simple statistical analyses
to simulating nuclear explosions at the molecular level. Scientific
computing usually refers to those tasks that would be otherwise
infeasible to compute by hand. Many such tasks require extraordinary
computational resources and are often accomplished by distributing
subtasks across many computers, which communicate through a
network of some kind. This network then becomes one of the most
important deciding factors in how quickly a task can be completed.
Supercomputers are often designed, and used, to solve problems of the
latter variety. One of the most important vendors in supercomputing
is Cray Inc., founded as Cray Research in 1972 by Seymour Cray. He
has been referred to as “the father of supercomputing” and was the
architect of his company’s first supercomputer, the Cray-1. The Cray-
1 was released in 1976 and, at the time, was the fastest computer in
the world. Throughout the 1980s Cray Inc. continued to offer some
of the fastest computers in the world, but they were surpassed in the
‘90s by designs such as Intel’s Paragon supercomputers and by IBM’s
Blue Gene supercomputers in the last decade. However, its latest
supercomputer Titan, developed at the Oak Ridge National Laboratory,
was recently ranked as the fastest supercomputer of 2012 as listed by
the TOP500 project. —Finn Kuusisto
