Megan Larko

OpenSFS President, Translucent

Megan Larko has involved in Linux High Performance Computing (HPC) for decades starting at NASA’s Goddard Space Flight Center in Greenbelt, MD and continuing in the U.S. DoD environment with SGI at Aberdeen Proving Ground, and HP (now HPE) at Ft. Meade, both in Maryland.  Megan is a graduate of the University of Maryland, College Park, and jokes that she also attended the college of “O’Reilly and Associates” based upon the knowledge she have gained reading books from that publisher. Megan has had Linux certifications from SAIR (one of the original Linux certs), RH, and CompTIA, and even “Lustre Administration and Support: Level One” dated July 2008 from Sun.  Megan enjoys her career as well as a few hobbies such as running and dog training.  Megan currently resides in western Pennsylvania, with her beloved spouse and goldendoodle mix.

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 15 years. The ALCF has deployed several large parallel 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. In 2020, ALCF deployed two 100PB Lustre file systems that serve as ALCF’s primary center wide storage systems. 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.

Dominic Manno

OpenSFS Secretary, Los Alamos National Laboratory

Dominic Manno is a Scientist in High Performance Computing at Los Alamos National Laboratory. He has a background in storage systems and software development. Dominic’s career began in HPC storage at LANL with contributions ranging from maintaining systems to integrating and deploying new Lustre file systems. Dominic, as HPC File System Technical Lead, is responsible for the design, procurement, and administrative team for all parallel file systems in LANL’s HPC data center. He has worked with the Lustre file system since 2014 with work including Lustre administration, file system performance tuning, and improving user performance for high-performance computing applications. Mr. Manno also co-leads a subset of storage research efforts at LANL’s Ultrascale Systems Research Center. Some our latest work includes re-examining disk failures and protection at extreme scales, designing next generation storage system deployments, and exploring hardware offload integration within ZFS. This team is also responsible for the current work in implementing direct I/O functionality into the ZFS file system.
