https://issues.apache.org/jira/browse/SOLR-17937 <!-- _(If you are a project committer then you may remove some/all of the following template.)_ Before creating a pull request, please file an issue in the ASF Jira system for Solr: * https://issues.apache.org/jira/projects/SOLR For something minor (i.e. that wouldn't be worth putting in release notes), you can skip JIRA. To create a Jira issue, you will need to create an account there first. The title of the PR should reference the Jira issue number in the form: * SOLR-####: <short description of problem or changes> SOLR must be fully capitalized. A short description helps people scanning pull requests for items they can work on. Properly referencing the issue in the title ensures that Jira is correctly updated with code review comments and commits. --> # Description GPU accelerated indexing was introduced in [SOLR-17892] which enables the user to leverage GPU for indexing. This PR adds GPU metrics to Solr's metric API . Also, these details have been added to the admin UI for visualization. These GPU metrics include name, used memory, free memory etc. # Solution I get the GPU details to Solr via cuVS's getGPUInfo() API. If Solr is started with the cuVS module enabled, this info is obtained using a long running thread that pulls this information every 5 seconds, and populating it to the Metrics API. The CuVS getGPUinfo() API does not support getting details for multiple GPUs in the system. We can just display the number of GPUs present and their names, but the memory values will not be reliable in a multi-GPU setup. # Tests Tested by starting solr with cuVS loaded, and GPU details were visible on the web-ui. Steps: 1. Build solr 2. Copy the modules: cp modules/cuvs/lib/*.jar server/solr-webapp/webapp/WEB-INF/lib/ 3. Start solr ./bin/solr start 4. GPU details should be visible on the web-ui http://localhost:8983/solr/#/ # Checklist Please review the following and check all that apply: - [ ] I have reviewed the guidelines for [How to Contribute](https://github.com/apache/solr/blob/main/CONTRIBUTING.md) and my code conforms to the standards described there to the best of my ability. - [ ] I have created a Jira issue and added the issue ID to my pull request title. - [ ] I have given Solr maintainers [access](https://help.github.com/en/articles/allowing-changes-to-a-pull-request-branch-created-from-a-fork) to contribute to my PR branch.
