What is APEX?

Collaborating to design, acquire, and deploy advanced technology high performance computing systems

The  Alliance for Application Performance at Extreme Scale (APEX) is a partnership between the Alliance for Computing at Extreme Scale (ACES) collaboration of Los Alamos National Laboratory and Sandia National Laboratories and the National Energy Research Scientific Computing Center (NERSC).

Focus

The APEX collaboration is focused on the design, acquisition, and deployment of advanced technology high performance computing systems for ACES and NERSC. In the FY20 timeframe, the APEX collaboration intends to procure two platforms:

Both platforms will focus on providing increased application performance and capability in addition to the deployment of Advanced Technology concepts necessary to meet the mission needs of the DOE’s NNSA Advanced Simulation and Computing (ASC) Program and the DOE Office of Science Advanced Scientific Computing Research (ASCR) Program.

APEX will also pursue areas of collaboration with vendors through Non-Recurring Engineering (NRE) contracts which will provide substantial value to the Crossroads and NERSC-9 systems, particularly with the goals of:

  • Increasing application performance
  • Reducing the need for data-motion of the course of an application’s workflow
  • Enhancing the resilience and reliability of the systems
Vendor access to the ASC Simulation Code Suite for the Crossroads/NERSC-9 RFP

Note: Each code will require special handling. Refer to section 3.5.4 of the APEX 2020 Technical Specification (pdf)

  • Lawrence Livermore National Laboratory
    • LLNL will be using the Mercury application. For details on how obtain the code and the relevant paperwork, vendors should contact Dave Richards.
