Officers

Sarp Oral

OpenSFS President, Oak Ridge National Laboratory

Dr. Sarp Oral is a Research Scientist at the Oak Ridge Leadership Computing Facility (OLCF) of Oak Ridge National Laboratory, where he is a member of the Technology Integration Group and the Team Lead for the File and Storage Systems projects. His research and development interests are parallel I/O and file system technologies, benchmarking, high-performance computing and networking, fault-tolerance.

Kevin Harms

OpenSFS Vice President, Argonne Leadership Computing Facility

Kevin joined the Argonne Leadership Computing Facility (ALCF) in 2007 working in the file system and storage area and that has remained his focus for the last 10 years. The ALCF has deployed several large GPFS and PVFS file systems during his tenure and Kevin has had various responsibilities from administering the day-to-day storage operations to performance tuning of application I/O. The initial deployments of the Intrepid and Mira GPFS file systems were the fastest GPFS file systems at the time. In 2016, ALCF deployed its first Lustre based file system and Kevin has been involved in the benchmarking and testing this new file system. As a member of the ALCF, Kevin has developed relationships within the HPC community and with key storage vendors. In addition to his role in the facility side, he has also spent a portion of his time working on I/O research as a member of Rob Ross’s I/O research team. Prior to joining ALCF, Kevin worked as a software developer in the Telecom industry.
