Description
GlideinWMS is a workload management and resource provisioning system widely used for distributed scientific computing. Recent development efforts have focused on simplifying token-based authentication which is finally starting to be adopted in production and improving support for High Performance Computing (HPC) resources. This presentation will highlight recent progress in these areas and discuss opportunities where additional collaboration with the HTCSS community could provide significant benefits.
A redesigned credential framework and new token generators simplify configuration. For example by enabling credentials and authentication options to be selected dynamically based on job ClassAds and target resources. Building on this improved infrastructure, GlideinWMS Frontend now supports automatic generation of self-signed SciTokens, providing a lightweight solution particularly well suited for testing environments and smaller virtual organizations (VOs).
Expanding access to HPC systems remains essential for maximizing available scientific computing capacity. With support and collaboration from the HTCSS community, GlideinWMS is broadening HPC integration through both established mechanisms, such as remote cluster access, and modern REST-based interfaces including SFApi and IRI Facility API. This work aims to reduce operational complexity while enabling more flexible and scalable access to heterogeneous computing resources.
