Overview
Traditionally scientists have managed the data using data formats, specifically developed for scientific datasets, and their associated API. The phenomenal increase in the size of the datasets has caused this model to become very inefficient. The lack of proper buffering. indexing and metadata management facilities accross files causes severe performance bottlenecks. Moreover with the increasing pervasiveness of parallel clusters for performing scientific visualizations, analysis and simulation we need to develop methods that are easily parallelizable. While traditional database technology provides a solution to most of the above said problems, the presence of large toolsets associated with specific formats discourage the scientists from shifting to traditional databases. We aim to provide holistic database like functionalities in order to ease the burden of data management on scientists.

Main Projects
The Maitri system improves the performance of data retrieval for scientists during the visualization/analysis phase while still allowing them to store data in the format of their choice. One major component of the Maitri project is bitmap indexing.
Panda reduces the write costs during large scale parallel disk writes. Log-based I/O is one focus of the project.
