SST v9.0.0 Released
SST v9.0.0 is now available and can be downloaded here
The SST 9.0.0 release contains several significant changes to the simulation core and its component/sub-component APIs which will become the default in the future. In addition, a number of performance and stability issues have been addressed allowing for reduced simulation times and better scalability.
A selection of the improvement highlights are:
SST-Core:
- Added ability to use custom time vortex modules for optimizing event delivery and simulator performance
- Added max/min fields for statistics in the core, these are now generated by default
- Fixes a bug which affects self-partitioning simulation models
- SST now issues warnings for zero latency links to help model debugging
SST-Elements:
- Added the Kingsley network-on-chip mesh model
- Added support for Ramulator
- Ariel can now forward application data into simulated memory subsystems
- Added HyperX topology to Merlin
- Fixes several bugs in Ariel memory allocation and page mapping
- Added Stake simulation core to Miranda for RISC-V simulation
- Added OpenSHMEM model support in Ember motifs
- Added new communication pattern motifs (both MPI and OpenSHMEM) for Ember
- Several fixes for MPI operations and timing in Ember/FireFly
- Improved performance for large-scale network simulations
- Fixed an alignment issue with Juno memory operations
- Fixes to Samba TLB model for scalable simulation
- Added the lightweight Shogun cross-bar models for high-performance interconnection of caches and processor cores
- Fixes several compiler warnings
- Added statistics in a number of elements/models to support more advaned analysis and insight
SST-Macro:
- Bug fixes and performance improvements
- Improved auto-skeletonization support
- Additional topologies and routing algorithms, including Dragonfly+ and progressive adaptive routing
- Integration of fcontext, no more Boost dependencies
- Defined hierarchy of congestion models for trading off accuracy/speed of simulation
