Advanced user environment design and implementation on integrated multi-architecture supercomputers

However, creating a convenient and effective user environment on modern supercomputers becomes more and more challenging due to the complexity of these large-scale systems. In this report, we discuss important design issues and goals in user environment that must support multiple compiler suites, various applications, and diverse libraries on heterogeneous computing architectures.

We present our implementation on the latest high-performance computing system, Yellowstone, which is a powerful dedicated resource for earth system science deployed by the National Center for Atmospheric Research. Our newly designed user environment is built upon a hierarchical module structure, customized wrapper scripts, pre-defined system modules, Lmod modules implementation, and several creative tools. The resulting implementation realizes many great features including streamlined control, versioning, user customization, automated documentation, etc., and accommodates both novice and experienced users.
