gassyfs - distributed in-memory file system over RDMA
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.
Testing
The file system is regularly tested with a variety of workloads. The following workloads are tested for each travis-ci.org build:
- Run the Tuxera POSIX test suite (test/posix.sh)
- Build Git and run unit tests (test/git.sh)
- samtools
An additional set of larger workloads (in addition to those listed above) are run prior to each release:
- Build the Linux kernel (test/kernel.sh)
- Build the Ceph storage system (test/ceph.sh)
- Multiple configurations of iozone (test/iozone.sh)
- Build PostgreSQL and run tests (test/postgres.sh)
