Melissa Romanus is a data management engineer for the National Energy Research Scientific Computing Center (NERSC) at Lawrence Berkeley National Laboratory. She is a member of the Operations Technology Group, where her research focuses on the ingestion, collection, analysis, and visualization of real-time streaming operational and systems data in data centers that support high performance computing systems. She earned her Bachelor of Science in Electrical & Computer Engineering (ECE) from Tufts University in 2010 and her Master’s in ECE from Rutgers in 2014.
Melissa’s current research interests are in operational data analytics in high performance computing (HPC) data centers and system architecture of large-scale data warehouses. She is also particularly interested in automating scientific workloads and data-driven science on HPC systems.
Melissa is a passionate advocate for mental health, increased neurodiversity in the workplace, and disability awareness. She currently serves as NERSC’s Inclusion, Diversity, Equity, and Accountability (IDEA) council chair for the labwide community, as well as in the CS Area. She is also the co-chair of the All-Access Employee Resource Group Mental Health Initiative. In addition, Melissa is the first-year delegate elect representing Berkeley Lab on the Council of UC Staff Assemblies (CUCSA), where she looks forward to serving the Lab community through staff engagement and making efforts to ensure all voices are heard and represented.

NVRAM-based Burst Buffers are an important part of the emerging HPC storage landscape. The National Energy Research Scientific Computing Center (NERSC) at Lawrence Berkeley National Laboratory recently installed one of the first Burst Buffer systems as part of its new Cori supercomputer, collaborating with Cray on the development of the DataWarp software. NERSC has a diverse user base comprised of over 6500 users in 700 different projects spanning a wide variety of scientific computing applications. The use-cases of the Burst Buffer at NERSC are therefore also considerable and diverse. We describe here performance measurements and lessons learned from the Burst Buffer Early User Program at NERSC, which selected a number of research projects to gain early access to the Burst Buffer and exercise its capability to enable new scientific advancements. To the best of our knowledge this is the first time a Burst Buffer has been stressed at scale by diverse, real user workloads and therefore these lessons will be of considerable benefit to shaping the developing use of Burst Buffers at HPC centers.
