Due to the previous commit we can end up with cores not assigned any cluster ID. For this, at the end we sort the CPUs by topology and assign cluster IDs to remaining CPUs based on pkg/node/llc. For example an 14900 now shows 5 clusters, one for the 8 p-cores, and 4 of 4 e-cores each. The local cluster numbers are per (node,pkg) ID so that any rule could easily be applied on them, but we also keep the global numbers that will help with thread group assignment. We still need to force to assign distinct cluster IDs to cores running on a different L3. For example the EPYC 74F3 is reported as having 8 different L3s (which is true) and only one cluster. Here we introduce a new function "cpu_compose_clusters()" that is called from the main init code just after cpu_detect_topology() so that it's not OS-dependent. It deals with this renumbering of all clusters in topology order, taking care of considering any distinct LLC as being on a distinct cluster.
HAProxy
HAProxy is a free, very fast and reliable reverse-proxy offering high availability, load balancing, and proxying for TCP and HTTP-based applications.
Installation
The INSTALL file describes how to build HAProxy. A list of packages is also available on the wiki.
Getting help
The discourse and the mailing-list are available for questions or configuration assistance. You can also use the slack or IRC channel. Please don't use the issue tracker for these.
The issue tracker is only for bug reports or feature requests.
Documentation
The HAProxy documentation has been split into a number of different files for ease of use. It is available in text format as well as HTML. The wiki is also meant to replace the old architecture guide.
Please refer to the following files depending on what you're looking for:
- INSTALL for instructions on how to build and install HAProxy
- BRANCHES to understand the project's life cycle and what version to use
- LICENSE for the project's license
- CONTRIBUTING for the process to follow to submit contributions
The more detailed documentation is located into the doc/ directory:
- doc/intro.txt for a quick introduction on HAProxy
- doc/configuration.txt for the configuration's reference manual
- doc/lua.txt for the Lua's reference manual
- doc/SPOE.txt for how to use the SPOE engine
- doc/network-namespaces.txt for how to use network namespaces under Linux
