SST 9.0.0 Released

SST v9.0.0 is now available and can be downloaded here

The SST v9.0.0 release follows the standard release process of having our point releases provide improved performance and stability.

A selection of the improvement highlights are:

General:

• SST v9.0.0 includes one of the largest overhauls of the internal simulation core and model APIs in recent years. Specifically, the release provides support for nesting of sub-components and a replacement of modules that increase the flexibility in model development and allow for better support in Python model definitions in future releases.
• Significant improvements to the internals of the SST core and several models to reduce simulation time and enhance model scalability when run on multiple nodes using MPI

Deprecation Notice:

• Elements SysC and HMC are now deprecated and are removed in this release.

SST-Core:

• SimpleMem subcomponent now uses the max_requests_per_cycle parameter correctly.

SST-Elements:

• Added the lightweight Shogun cross-bar model for modeling high-performance cache/core connectivity
• Removed SysC
• Removed HMC
• Bus component will now process an unlimited number of messages per cycle if the drain_bus parameter is set.
• memHierarchy component now accepts the network_link_control parameter; defaults to merlin.linkcontrol.
• Added OpenSHMEM support in Ember/Hermes and FireFly models. Ability to model fine-grained memory operations and atomics across a network fabric.
• Improved accuracy of memory models for detailed network communication stack (Ember/Hermes)

SST-Macro:

• Bug fixes and performance improvements
• Improved integration with the SST-Core
• Improved support for OTF2 trace formats
• Enhanced skeletonization support
