Resource Allocation for Sequential Decision Making Under Uncertainaty : Studies in Vehicular Traffic Control, Service Systems, Sensor Networks and Mechanism Design
(2017-11-27)
A fundamental question in a sequential decision making setting under uncertainty is “how to allocate resources amongst competing entities so as to maximize the rewards accumulated in the long run?”. The resources allocated ...
A Systems Perspective of Software Runtime Bloat - Origin, Mitigation and Power-Performance Implications
(2018-03-08)
Large flexible software systems tend to incur “bloat”, here defined as the runtime overhead induced by the accumulation of excess functionality and objects. Removing bloat is hard as these overheads are a side-effect of ...
Investigations on CPI Centric Worst Case Execution Time Analysis
(2018-03-19)
Estimating program worst case execution time (WCET) is an important problem in the domain of real-time systems and embedded systems that are deadline-centric. If WCET of a program is found to exceed the deadline, it is ...
Online Learning and Simulation Based Algorithms for Stochastic Optimization
(2018-03-07)
In many optimization problems, the relationship between the objective and parameters is not known. The objective function itself may be stochastic such as a long-run average over some random cost samples. In such cases ...
Automatic Storage Optimization of Arrays Affine Loop Nests
(2018-03-01)
Efficient memory usage is crucial for data-intensive applications as a smaller memory footprint ensures better cache performance and allows one to run a larger problem size given a axed amount of main memory. The solutions ...
Reeb Graphs : Computation, Visualization and Applications
(2018-02-23)
Level sets are extensively used for the visualization of scalar fields. The Reeb graph of a scalar function tracks the evolution of the topology of its level sets. It is obtained by mapping each connected component of a ...
Reconstruction of 3D Neuronal Structures
(2018-03-17)
Microscopic analysis of biological structures can be significantly enhanced by representing the object of study as a three-dimensional entity. To assist neurobiologists investigate the molecular mechanisms involved in ...
An Optimizing Code Generator for a Class of Lattice-Boltzmann Computations
(2018-03-09)
Lattice-Boltzmann method(LBM), a promising new particle-based simulation technique for complex and multiscale fluid flows, has seen tremendous adoption in recent years in computational fluid dynamics. Even with a ...
Studies In Automatic Management Of Storage Systems
(2015-11-16)
Autonomic management is important in storage systems and the space of autonomics in storage systems is vast. Such autonomic management systems can employ a variety of techniques depending upon the specific problem. In this ...
Visual Analysis Of Interactions In Multifield Scientific Data
(2014-11-14)
Data from present day scientific simulations and observations of physical processes often consist of multiple scalar fields. It is important to study the interactions between the fields to understand the underlying phenomena. ...
