This new version comes with changes from 2023-2025.
Bug fixes:
- All reverse handlers for 1-D Dragonfly (dally) have been checked than to downstream reverse handler checker in ROSS
- Better performance when growing simulation to 8K virtual nodes (eg, 8448-node dragonfly network)
New features:
- Workloads can be generated using Union (https://github.com/SPEAR-UIC/Union)
- Dragonfly hybrid mode implemented, we can now run a flow simulation instead of a packet-based one after gathering some data in the latter (network surrogacy). We have seen up to 70x acceleration gains
- Hybrid mode for MPI replay applications: we can run the simulation in high-fidelity and then switch after a couple of app iterations to a surrogate. Acceleration gains are proportional to the number of iterations skipped by all apps
- Experiment examples repo up to date (https://github.com/CODES-org/experiments)
Others:
- Support for autoconf has been removed
