Here's a list of current projects running on PRObE resources


ExAlt: Robust Exa-byte Storage

The ultimate goal of this project is to build a storage system which is scalable to exa-bytes and robust against arbitrary faults. Systems with such scale can consist of tens of thousands of machines, each with 10-20 disks, and geo-replicated data centers for durability and availability. We're expecting to provide end-to-end correctness guarantees to this system despite arbitrary faults like disk corruption, memory corruption, or CPU error.

FAWN: A Fast Array of Wimpy Nodes

FAWN is a fast, scalable, and energy-efficient cluster architecture for data-intensive computing. A FAWN cluster links together a large number of "wimpy" nodes built using energy-efficient processors and small amounts of flash memory into an ensemble cluster that can perform the same amount of work as a traditional cluster but at a fraction of the power.

PLFS: Parallel Log Structured Filesystem

The Parallel Log Structured Filesystem Project (PLFS) is a joint project between PDL and Los Alamos Nation Labs (LANL) that is part of the Institute for Reliable High Performance Information Technology (IRHPIT) collaboration between CMU and LANL. PLFS is an open source filesystem that can be inserted between scientific applications and parallel storage system to greatly improve I/O performance.

USRC: Ultrascale Systems Research Center

The Ultrascale system research center is focused on investigating large-scale to exascale distributed system software. PRObE allocations will be used for scaling experiments with our code and traditional code for comparison studies and validation of simulations.
