    CERN

    CERN

    Video conferencing only

    Kostis:

    1. PSB test case on single/double precision
      • higher error than for other test cases, but still within statistical error
    2. Dynamic load balancing
      • controlled way to test imbalance in a cluster
      • shows good results for DLB algorithm

     

    Alex

    • Section object partially implemented
      • Naming convention to be discussed
      • Section length is a programme -> should be renamed to radius/orbit?
        • Next time: review EOM on orbit convention; fixed section length and time-varying orbit programme?
    • New in travis: set up ssh key (t.b.d. with Kostis)
      • Automatic docs generation
    • Naming conventions
      • Objects: Ring*, RF* (e.g. Ring, RingSection)
      • Module names: try avoiding _ ?
        • Brainstorming on shorter names in codimd for next time; we'll decide during the meeting
      • Attribute names: to be reviewed on demand

    Panagiotis

    • Will circulate first version of complete GPU version for people to test

    AOB

    • Forum question on website concerning sparse beam and multiple bunches -- Alex and Simon please reply
    • New website: https://test-blond.web.cern.ch/
      • Please check and bring up any additions you would like to make in the next meeting; afterwards, we'll make it online
