The Laboratory's Multiprogrammatic and Institutional Computing (M&IC) Program brings tailored, cost-effective classified and unclassified computing services to LLNL programs and scientists.

The Livermore Computing Center (LC) is primarily funded through the Advanced Simulation and Computing (ASC) and M&IC Programs. Because M&IC represents a broadening of services to multiple programs and to institutional users, such as Laboratory Directed Research and Development (LDRD) researchers, there are two related thrusts:

  • Multiprogrammatic Computing provides options for any non-LDRD effort to utilize LC in a cost-effective manner, either through purchasing a substantial block of time or through investing in the equipment required to meet the program's needs.
  • Institutional Computing grants researchers, independent of programmatic connection, access to institutional computer time, including LDRD, Grand Challenges, and others approved by the Deputy Director of S&T. A special category of institutional computing is the Grand Challenge Program, which allocates significant capability resources to push the boundaries of high performance computing and simulation.

M&IC and the Stockpile Stewardship Program (SSP) have worked together to make LLNL a premier institution for computational and simulation science. Such standing is vital to the continued success of LLNL science programs and to the recruitment and retention of top scientists. M&IC constantly works at balancing investments to meet the widespread demand for capacity computing and provide cost-effective capability platforms. In fielding computing platforms and advanced data assessment capabilities, M&IC leverages the investments of the SSP for the mutual benefit of the SSP, other programs, and LLNL.

Through strong and consistent LLNL investments, M&IC's computing resources are used across LLNL to push the limits of computing and its application to simulation science. Through these efforts, LLNL has become a premier laboratory in simulation science, which has resulted in world-class scientific insight and has facilitated the recruitment and retention of leading physical and computer scientists. All LLNL programs and projects are bolstered through these efforts and provide LLNL scientists with access to world-class systems.

Institutional Computing Grand Challenge program celebrates its 18th campaign

Research projects ranging in scope from simulations predicting the impact of climate change on California to calculations of electrocatalyst instability in hydrogen production systems were among those allocated time on Laboratory supercomputers under the recently announced Institutional Unclassified Computing Grand Challenge Awards. The 18th Annual Computing Grand Challenge campaign awarded over 87 thousand node hours per week to projects such as these that address compelling, large-scale problems, push the envelope of capability computing, and advance science. “As in past years, the diversity and quality of this year’s proposals showcase the scientific breadth and excellence of LLNL’s computational science community” said Bruce Hendrickson, Computing Associate Director.  “These activities are part of what makes the Lab such an exciting place to work.”
