- Run Performance Results
- CS - Jeff
- Run: Tested SANDAG model with identical software image run using different hardware.
- Result: Hardware is not the root of the issue.
- Original Hypothesis: Issue with memory bandwidth.
- New Hypothesis: Supporting a different hardware limitation, which could be the issue - On-chip memory cache. If run only with 36 processes, each thread can grasp 5-6 megabytes of memory for its calculations. Computations can compute faster with fewer threads.
- CS - Jeff
- How to process in the multi-process configuration, which agencies will inevitably run? Will not necessarily see improved performance with increased processes.
- RSG to re-run according to Jeff’s hypothesis.
- New columns added to Spreadsheet:
- Numba Multi-Threading Limits
- L3 Cache
- L3 Cache per Numba Thread
- ActivitySim Consortium Meeting (7/2): Small Engineering Team Meeting (Tech Team focused)
