Meeting with Avinash and Intel - 2016/4/26
Discussion:
- We indicated that we are able to get 420,000 MB/s from stream in Flat All2All and Quadrant modes since the recent BIOS update
- Intel would like us to investigate the Quadrant model in Flat mode because they think we should get 440,000 MB/s
- Intel examined our NUMA output from the system and believes that we are not running a newer firmware because the logical processes should be nicely ordered.
- Intel said they only expect at 5-6% variance between NUMA clusters.
- Vitali present his HACC results on KNL (which were all good and have improved since A0)
- Irv from Intel joined to help debug our BIOS setup.
- He indicated that our BIOS is provided by PCSD division which does there own packaging and he doesn't know what they have.
- Intel development runs BIOS created by him.
- After some discussion, we need someone from Intel to help us debug the issue
- Avinash will work to assign someone to help us
- It appears Intel development has their own development boards and do not use Adams Pass boards
Action Items:
- Argonne: Run our stream test cases in Flat-Quadrant configuration and try to achieve 440,000 MB/s using 1 or 2 threads per core
- Intel: Assign someone to help investigate the BIOS version/configuration on our box
- Argonne/Intel - setup a meeting in two weeks to discuss progress. Scott will present his NEK results.
