GassyFS is a FUSE-based file system that stores data in distributed remote memory. Remote memory is managed and accessed using GASNet, which supports RDMA over a wide variety of high-performance network interconnects, as well as supporting slower network access methods such as UDP that are useful for development. The Gassy file system is intended to be used in a manner analagous to tmpfs, but when the amount of RAM needed exceeds that of a single node.

The file system is regularly tested with the following workloads.
