SST v5.1 Released
SST v5.1.0 Release is Now Available!
The SST project teams are pleased to announce that the v5.1.0 of the simulation framework and components are now available for download here. In the next few months SST will be moving to Github so stay tuned for updates on the new repositories.
General:
- SST v5.1.0 includes several fixes to issues in the core and some performance tweaks which have been based on end-user feedback and research simulations.
- No components within SST now make MPI calls
Core:
- SST v5.1.0 now correctly sets LD_LIBRARY_PATH information for all components (previously some configurations may have missed some memory simulation libraries)
- SST Params classes now correctly return int64_t for integer finds
- Fix for XML inputs which have zero parameters
- SST core subclasses output formats and provides new JSON formatted output for components/elements
- SST core provides count down to zero exit conditions for components allowing simulations to cleanly exit with a globally known exit condition
- SST core now provides support for subcomponents to dynamically load subcomponents
- SST core provides shared memory regions between components significantly reducing memory overhead for large scale network simulations with complex job layouts
- Output classes can now redirect output on a per rank basis
- Statistics in parallel runs are now correctly configured
Components:
- Ariel now allows environment variables to be controlled or loaded from the simulation’s environment
- Ariel now allows address translation capabilities to be disabled during simulation
- Ariel now allows page tables to be pre-populated by user files and then dynamically allocated if spare pages exist
- Ember now includes additional motif testing
- Memory leak fix for large FireFly simulations
- Fixes bug in Ember simulations using static tables for loading AMR data
- Network simulations can now correctly handle out of order packet arrivals to support adaptive/dispersive routing schemes
- Memory leaks in several network simulation components are fixed
