چکیده (انگلیسی):

“Data mining” for “knowledge discovery in databases” and associated computational operations first
introduced in the mid-1990 s can no longer cope with the analytical issues relating to the so-called “big
data”. The recent buzzword big data refers to large volumes of diverse, dynamic, complex, longitudinal
and/or distributed data generated from instruments, sensors, Internet transactions, email, video, click
streams, noisy, structured/unstructured and/or all other digital sources available today and in the future at
speeds and on scales never seen before in human history. The big data also being described using 3 Vs,
volume, variety and velocity (with an additional 4th V for “veracity” and more recently with a 5th V for
“value”), requires a set of new technologies, such as high performance computing i.e., exascale,
architectures (distributed or grid), algorithms (for data clustering and generating association rules),
programming languages, automated and scalable software tools, to uncover hidden patterns, unknown
correlations and other useful information lately referred to as “actionable knowledge” or “data products”
from the massive volumes of complex raw data. In view of the above facts, the paper gives an introduction
to the synergistic challenges in “data-intensive” science and “exascale” computing for resolving “big data
analytics” and “data science” issues in four main disciplines namely, computer science, computational
science, statistics and mathematics. For the realisation of vital identified foundational aspects of an effective
cyber infrastructure, basic problems need to be addressed adequately in the respective disciplines and are
outlined. Finally, the paper looks at five scientific research projects that are urgently in need of high
performance computing; this is in contrast to the earlier situations where private business enterprises were
the drivers of better modern and faster technologies.
