WMCore is a meta project providing multiple software for the CMS Workload Management system, such as WMAgent, ReqMgr2, Global WorkQueue, WMStats and ReqMgr2 MicroServices. It also provides core libraries to other Data Management and Workload Management (DMWM) CMS services, like CRABServer, DBS3, Tier0, Unified.
General information, as well as development and testing documentation, can be found in our GitLab docs, as the WMCore wiki has been phased out since the year 2024.
For guidance on setting up a development/testing environment and how to contribute to WMCore, please refer to the CONTRIBUTING guidelines.
For project support and discussions, please join us on the CMS O&C organization in CERN Mattermost. The relevant Mattermost channels are either WM Dev or WM Ops.
