DSSL is interested in the design, development, and evaluation of next-generation storage and file systems. Specifically, the research focuses on tailoring these systems for growing data demands of modern high-end computing applications running on existing as well as emerging multicore architectures. To this end, we aim for innovation in systems that range from large-scale distributed setups to specialized kernel-level optimizations.
