GekkoFS 0.9.1 released

This release includes new features, support for a new metadata backend (Parallax) as an alternative to RocksDB, bug fixes and general updates to the code base. Further, users can collect file system statistics that are accessible via a regular text file. GekkoFS can also connect and push the statistics to the Prometheus monitoring system directly. Finally, GekkoFS now offers the gkfs script to more easily deploy GekkoFS daemons on multiple nodes in a supercomputing environment. Please refer to the change log for more detailed information.

GekkoFS 0.9.0 released

This release features many additions, improvements, bug fixes, and stability updates to the code base. Among others, this release includes considerable overhauls of dependency scripts, testing facilities, and documentation as well as optimized metadata operations and a new distribution mode (the guided distributor) which allows defining a specific distribution of data on a per directory or file basis. Moreover, GekkoFS is now using C++17 and supports the most recent dependencies. Finally, GekkoFS is now published under the GNU General Public License version 3. Please refer to the change log for more detailed information.

GekkoFS 0.8.0 released

This release adds a new execution mode called GekkoFWD that allows GekkoFS to be used as a user-level I/O forwarding infrastructure. Many thanks to Jean Bez for this huge contribution. This release also brings support for Verbs and Omni-Path as communication protocols plus improved stability to the code base through the addition of a Python testing harness designed to assist developers with integration tests.

New publication: “Adaptive request scheduling for the I/O forwarding layer using reinforcement learning”

In this paper, we propose an approach to adapt the I/O forwarding layer of HPC systems to applications’ access patterns. We propose to do it dynamically at runtime, using a reinforcement learning technique to observe the I/O workload of the system and determine the best parameter value for each observed access pattern during its execution.
