Analyzing how species are distributed on the Earth has been one of the fundamental questions in the intersections of environmental sciences, geosciences and biological sciences. With world-wide data contributions, more than 375 million species occurrence records for nearly 1.5 million species have been deposited to the Global Biodiversity Information Facility (GBIF) data portal. The sheer […]

Multiple sequence alignment is a crucial task in a number of biological analyses like secondary structure prediction, domain searching, phylogeny, etc. MSAProbs is currently the most accurate alignment algorithm, but its effectiveness is obtained at the expense of computational time. In the paper we present QuickProbs, the variant of MSAProbs customised for graphics processors. We […]

Scheduling applications tasks across heterogeneous clusters is a growing problem, particularly when new upgraded components are added to a parallel computing system that may have originally been homogeneous. We describe how automatic and just-in-time source code generation techniques can be used to make the best parallel decomposition for whatever resource is available in a heterogeneous […]

In this thesis, I investigate computational questions in Markov chain Monte Carlo (MCMC). I am investigating one new MCMC method called the stretch move ensemble sampler [3]. I have looked at the performance of this algorithm, in terms of acceptance rates, autocorrelation time and compute performance. The thesis describes a parallel implementation of the algorithm […]

GPGPU (general purpose computing on graphics processing units) programming is one interesting way to increase performance; unfortunately it is not easily done, because extensive knowledge of the GPU’s architecture is required to write programs that are faster than CPU programs. Obsidian is an embedded domain specific language for writing GPGPU kernels, which tries to make […]

In today’s digital world, Data sets are increasing exponentially. Statistical analysis using clustering in various scientific and engineering applications become very challenging issue for such large data set. Clustering on huge data set and its performance are two major factors demand for optimization. Parallelization is well-known approach to optimize performance. It has been observed from […]

Image edge detection is an important technique in the area of image processing with wide applications in Medicine, Remote sensing, military to mention a few. There are conventional as well as improvised edge detection algorithms depending on the application. The choice of the technique in most cases depends on the application and image in question […]

The turbulent transport of a passive scalar is an important and challenging problem in many applications in fluid mechanics. It involves different range of scales in the fluid and in the scalar and requires important computational resources. In this work we show how hybrid numerical methods, combining Eulerian and Lagrangian schemes, are natural tools to […]

In 2010, a special time-domain beamforming algorithm was presented at the Berlin Beamforming Conference [3]. This algorithm is primarily designed for the sound source localization on moving objects with known velocity (e.g. freight trains). By determining the object trajectory, the acoustic map’s quality can be improved with respect to the Doppler effect. The bottleneck of […]
