The NUG Charter was last updated July 26, 2019, with minor corrections on May 19, 2020.
The National Energy Research Scientific Computing Center (NERSC) is the principal provider of high performance computing services to Office of Science programs. NERSC’s mission is to accelerate scientific discovery at the DOE Office of Science through high performance computing and data analysis. NERSC Users Group (NUG) is the user group for the NERSC facility at Lawrence Berkeley National Laboratory. NERSC is developed and maintained under the auspices of the Office of Science, U.S. Department of Energy (DOE).
Through the NERSC Executive Board, known as NUGEX, NUG provides feedback and advice to NERSC on the current state and future of NERSC resources and services. NUG exists to promote effective communication between NERSC and its users, collaborate with the center to enhance user productivity, and help ensure that NERSC continues to be a valuable world-class HPC resource available to the DOE Office of Science user community. To these ends, NUG will maintain communications through appropriate means, such as regular meetings, electronic mailing lists, shared databases, and web pages. In addition, NUGEX promotes a vibrant user community and interdisciplinary exchange of ideas and experiences.
All principal investigators with a reviewed resource allocation at NERSC, and all active users associated with such research accounts, are automatically members of NUG. Participation in NUG's activities is open to all NERSC users. NERSC will provide staff and administrative resources to facilitate the meetings and other business of the NERSC Users Group.
Executive Board (NUGEX)
The organizational body for NUG is its Executive Board (NUGEX). It manages the activities of the user group. NUGEX consists of 21 user representatives who each maintain awareness of and represent the interests of the user community. Each of the six program offices of the Office of Science (BER, BES, HEP, NP, OASCR, and OFES) has three representatives on NUGEX. Three additional members of NUGEX will represent the user community at large. The NUGEX Chair and executive board coordinate NERSC User Group activities and initiatives. The members of this executive board are elected by NUG members in elections administered by NERSC with the help of NUGEX. All terms are for a duration of three years. The three-year terms are for three consecutive calendar years. Approximately one-third of the available NUGEX positions are elected annually. There are no term limits.
The NUGEX chair and the vice chair are elected annually by the members of the executive board from among its ranks following the election of new members. NERSC solicits nominations and conducts the election of the chair and vice chair from among NUGEX members. The NUGEX chair is responsible for convening NUGEX at regular intervals and assures that NUG can carry out its purpose effectively. The vice chair takes on the chair’s responsibilities when the chair is not available.
Topics that require a vote, such as charter adoption and changes or new permanent working groups, will use a simple majority approach. People who do not participate are assumed to agree with the proposed changes. NUGEX will have a minimum of two days to respond to electronic requests for votes. The NUGEX chair will provide the results of the voting to NERSC.
Task Forces and Working Groups
When appropriate, NUGEX will appoint task forces and working groups to address specific issues related to NERSC. NUGEX will name the subcommittee membership and the subcommittee lead and define its charge. Such subcommittees should be formed from the appropriate experts and interested parties. The leadership and/or membership may include persons outside NUG. Such subcommittees should regularly report back to NUG at its monthly general meetings. Standing working groups will have dedicated time on monthly agendas. If the lead of the working group is absent, an alternate may be nominated to present. Task forces may be formed and disbanded by agreement of NUGEX chair(s) and NUGEX members.
