My general research area is parallel and distributed systems. My main projects, Nswap and Nswap2L, implement fast backing storage systems for cluster computers. Nswap is a network RAM system for Linux clusters. Nswap allows individual cluster nodes with over-committed RAM to locate and use idle RAM of other nodes in the cluster. The goal of the project is to speed-up the runtime of cluster applications by avoiding the slow swapping to disk that normally occurs when a node doesn't have enough RAM space for the programs it is running. Nswap2L implements a virtualization layer on top of a heterogeneous collection of cluster storage devices including Nswap Network RAM, Flash SSD, disk and other cluster-wide backing store. It is added as a single block device to individual cluster nodes that transparently manages block placement on the set of underlying heterogeneous storage devices.
