Dr. Mohr joined NICS as an HPC system administrator in Jan 2009. His primary focus is on parallel file system deployment and support (Lustre, GPFS). Additional contributions to the NICS team have included Cray XT5 and XC30 support, SGI UV support, account management system, monitoring infrastructure, and XSEDE data services.

Prior to joining NICS, Dr. Mohr worked at the Ohio Supercomputer Center (OSC) for eight years, where he was an administrator for the HPC Linux clusters. Rick wrote software for managing OSC's clusters, deployed much of the monitoring infrastructure, and designed/supported the web infrastructure for portal deployments.
