The end goal is to increase the robustness of the code in the mid- to + long-term. +- 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 + once. + *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. -- GitLab From 8988ba812df95a109353ff064fa1b0a3a002cdca Mon Sep 17 00:00:00 2001 From: Alberto Miranda Date: Tue, 15 Sep 2020 16:58:59 +0200 Subject: [PATCH 3/3] Bump version --- CMakeLists.txt | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/CMakeLists.txt b/CMakeLists.txt index 965bea6fd..2f3a2a190 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -2,7 +2,7 @@ cmake_minimum_required(VERSION 3.6) project( GekkoFS - VERSION 0.7.0 + VERSION 0.8.0 ) enable_testing() -- GitLab
