Title: Auks: A Kerberos and HPC batch system


This talk presents Auks, an opensource application that provides kerberos credential support in HPC batch system, and its integration in Slurm, an opensource resource manager for large clusters.

Auks is a multithreaded client-server application (not an authentication system) that uses kerberos authentication and encryption primitives to securely provide a centralized credential repository.

Issues concerning kerberos support in multi-thousand node clusters, like long running jobs and scalability, will be discussed as well as planned enhancements.
