## [Unreleased]
## [0.8.0] - 2020-09-15
## Added
- Both client library and daemon have been extended to support the ofi+verbs
- A new Python testing harness has been implemented to support integration
tests. The end goal is to increase the robustness of the code in the mid- to
- The RPC protocol and the usage of shared memory for intra-node communication
no longer need to be activated on compile time. New arguments
`-P|--rpc-protocol` and `--auto-sm` have been added to the daemon to this
effect. This configuration options are propagated to clients when they
initialize and contact daemons.
- Native support for the Omni-Path network protocol by choosing the `ofi+psm2`
RPC protocol. Note that this requires `libfabric`'s version to be greater
than `1.8` as well as `psm2` to be installed in the system. Clients must set
`FI_PSM2_DISCONNECT=1` to be able to reconnect once the client is shut down
*Known limitations:* Client reconnect doesn't always work. Apparently, if
clients reconnect too fast the servers won't accept the connections. Also,
currently more than 16 clients per node are not supported.
- A new execution mode called `GekkoFWD` that allows GekkoFS to run as
a user-level I/O forwarding infrastructure for applications. In this mode,
I/O operations from an application are intercepted and forwarded to a single
GekkoFS daemon that is chosen according to a pre-defined distribution. In the
daemons, the requests are scheduled using the AGIOS scheduling library before
they are dispatched to the shared backend parallel file system.
- The `fsync()` system call is now fully supported.
## Changed
- Argobots tasks in the daemon are now wrapped in a dedicated class,
effectively removing the dependency. This lays ground work for future
non-Argobots I/O implementations.
- The `readdir()` implementation has been refactored and improved.
- Improvements on how to the installation scripts manage dependencies.
## Fixed
- The server sometimes crashed due to uncaught system errors in the storage
backend. This has now been fixed.
- Fixed a bug that broke `ls` on some architectures.
## [0.7.0] - 2020-02-05
## Added
- Adedd support for `eventfd()`and `eventfd2()` system calls.

GekkoFS is a file system capable of aggregating the local I/O capacity and performance of each compute node
in a HPC cluster to produce a high-performance storage space that can be accessed in a distributed manner.
This storage space allows HPC applications and simulations to run in isolation from each other with regards
