description: "SAND2025-04369O\nMaskman is a user-friendly tool designed to create\
  \ hex masks, which are essential for optimizing application performance in high-performance\
  \ computing environments. By converting a list of integers into binary and then\
  \ hex masks, Maskman simplifies the process of setting application affinity. This\
  \ ensures that software runs efficiently on specific nodes within a computing cluster.\
  \ Ideal for researchers and developers, Maskman streamlines the preparation of inputs\
  \ for HPC schedulers, enhancing resource management and improving overall system\
  \ performance. Sandia National Laboratories is a multimission laboratory managed\
  \ and operated by National Technology & Engineering Solutions of Sandia, LLC, a\
  \ wholly owned subsidiary of Honeywell International Inc., for the U.S. Department\
  \ of Energy’s National Nuclear Security Administration under contract DE-NA0003525."
