Big Data, Small Testing ?

– by Prof. Jayant Haritsa, IISc

IEEE Bangalore Section

Outline of the talk

Big Data has become the buzzword of choice in recent times, especially in the software industry. The accompanying hoopla has spawned frenetic claims foretelling the development of great and wondrous solutions to Big Data challenges. However, there is very little said about the testing of such systems, an essential prerequisite for deployment. In this talk, we will discuss the research challenges involved in the testing process, especially from the database perspective. We will also present CODD, a graphical tool that takes a first step towards the effective testing of Big Data deployments through a new metaphor of “data-less databases”. CODD is currently in use at industrial and academic institutions worldwide.

Invited Talks:

High Performance networks in multicore/manycore computing era

– by Atul Bodas

IEEE Bangalore Section

Outline of the talk

With emergence of manycore and multicore computing, traditional programming paradigms are changing. Running an application over hundreds of thousands of computing core and extracting performance now equires the application developers to be aware of underlying architecture of the system.

It is, however observed that these efforts are centered largely around the compute elements of the system, with network component being assumed to be completely transparent, needing no active involvement of the application developer. This assumption however is erroneous, considering various challenges involved in network design and making efficient use of the resources.

This talk is aimed towards making users aware of challenges involved in design of contemporary HPC network design, and debating whether time has come for the application developers to become “network aware” as well so as to get maximum benefit and performance out of their applications.

Bits to Barrels – New ways of Computing in the Energy Industry

– by Dr. Chiranjib Sur

Outline of the talk

In this presentation, I will give an overview of the kind of non-conventional computational effort which is required in the oil and gas industry to meet the energy demand for modern era. The presentation will outline problems from different areas – ranging from micro to macro scale. I will touch upon areas like material simulation in quantum / classical scale, fluid structure interaction, numerical techniques to model oil reservoir and also about geophysical imaging of subsurface. Some of the problems can be classified as purely high performance number crunching and some are driven by data and analytics.

These problems are very challenging to solve on their own and it certainly needs attention from experts in cross discipline – both from domain and computer science.

I will also talk about other community efforts in this areas which might be of interests to the community.

Using Machine Intelligence for Healthcare

– by Dr. Geetha Manjunath

Outline of the talk

Extreme digitization in every field of life is driving Data Analytics to be in the core of any new innovation that improves quality or efficiency. In addition, analytics applications in healthcare domain can create tremendous societal impact. It is also a data rich environment with a lot of heterogeneity in the available data – physiological measurements, radiology images, claims, clinical notes and so on. Healthcare poses several interesting technical challenges to analytics algorithms due to large volumes, velocity, imbalance in data, high levels of accuracy expected and considerable missing information in the input, among others. In this talk, I will share some examples of novel machine intelligence algorithms that we have developed towards improving outcomes in critical care and cancer screening.

Green Software Development and Green Programming

– by Y.N. SRIKANT

Outline of the talk

The importance of saving energy in general need not be over-emphasized.Computing equipment of various kinds, e.g., mobile phones, laptops, portable games, desktops, servers, and large data centres, all deserve to be consideredseriously as candidates for saving energy. The techniques for saving energy that need to deployed at various levels, e.g., in a data centre and in an embedded device, will be certainly different. The former looks at work load characterization and the latter heavily depends on the compiler to do the job.

This talk will provide an overview of various techniques for saving energy in software from a compiler point of view and provide a glimpse of the important area of green programming.

Efforts in realization of scalable quantum computing by exploiting quantum correlations and ultrafast dynamics of complex systems: vibrating molecules, colloidal clusters, and mixed liquids

– by Debabrata Goswami

Outline of the talk

We highlight the importance of the dynamical aspects of complex systems by using emtosecond laser pulses to probe and perturb the dynamics of infra-red dye molecules in several environments and confined conditions. Importance of obtaining the molecular description on relation between dynamics of solute molecule and solute-solvent interactions arises from the fact that the dynamic and static properties of dye molecules are strongly affected by the surrounding solvent molecules. Modulation of the immediate micro-environment of solute can tinker the dynamics of the solute.

In a similar vein, programmable ultrafast pulse shaping or photon flux confinement also result in spatiotemporal control of dynamics. These are demonstrated through femtosecond pump-probe studies or by invoking pulsed optical traps for monitoring complex systems. We will finally show how confinement enables control and how physics principles can be used to unravel the dynamics of complex systems and that it is, in fact, much simpler than one presumes a priori.

These efforts form the basis of our efforts in realization of scalable quantum computing by exploiting quantum correlations and ultrafast dynamics of complex systems: the main theme of the talk focuses on this very aspect of the possible robust implementation.

Memory Architecture for Exa-scale Computing: Challenges and Solution Directions

– by Sparsh Mittal

Outline of the talk

Memory system plays the primary role in determining performance, reliability and power consumption of all computing systems, ranging from hand-held embedded systems to massive supercomputers. The ever-increasing data-intensive nature of state-of-the-art applications demands significantly higher performance within the constraints of power and cost, beyond what conventional memory technologies and architectures can provide. For example, more than 100 hours of video and 250K photos are uploaded every minute to YouTube and Facebook, respectively.

Similarly, future exascale supercomputers (i.e., those capable of 1000 petaflop computations per second) will require at least 100 petabytes of main memory, which, if designed with today’s DDR3 DRAM, would consume 52MW power, which is far more than the 20 MW power budget mandated for the entire system. This talk will highlight the challenges, such as power consumption and reliability, in designing memory systems for next-generation exascale computing systems. It will also point out possible solution directions, such as emerging non-volatile memory, heterogeneous memory systems, near-threshold computing, etc.
