Professor Sarangi will be examining construction of wait free multiple concurrent streams to address the scalability and QoS guarantees in modern storage systems. In the emerging world of SCM / In-memory and multi-cores, the existing lock mechanisms and programming paradigms are being challenged and STM too finds resonance. Wait-freedom has been chased for a number of years, but of late practical designs have started to emerge, which achieve system goals without bringing a system to snails-pace. Prof. Sarangi’s work focuses on an important computational aspect in storage based algorithms – scheduling and propose wait free parallel algorithms and evaluate them.
