SST V7.1.0 Release Notes
The changes in v7.1.0 of the Structure Simulation Toolkit (SST) are divided into three areas: general, PDES-core and integrated elements.
General:
- SST v7.1 includes optimizations to enable better performance and scaling for multi-node and multi-threaded simulations
SST-Core:
- Updates to SST Element component information definitions including version information and additional documentation. These changes lay the foundation for more better component support into SST 8.0 and beyond
- Changes to support compile and link flags for external elements on Linux and Mac OS-X
- Updates to autoconf to support modern use of tar utility
SST-Elements:
- Fix for crashes that can occasionally occur in Ariel/memHierarchy
- Updates to autoconf to support modern use of tar utility
SST-Macro:
- DUMPI configuration fixes, particularly for deprecated MPI-2 functions in MPI-3
- Added compiler support for static function and C++ static member variables in skeleton apps
- Linker fixes for generating skeleton app element libraries. Updates to new ELI interface.
- Improved parallel partitioning on top of sst-core
- Documentation updates
Known Issues (see open issues for repos):
Known incompatibilities:
- Only PIN 2.14 is supported on SST 7.1 due to newer PIN based tools inability to support non-Intel based libraries.
- PIN 2.14 does not run on newer Linux Kernels (ex. Ubuntu 16.04) or OSX 10.12
- Ariel Element requires PIN
- Prospero (Pin Feature) requires PIN
- memHierarchy Element (Sieve Feature) requires Ariel
- Scheduler Element is not multi-core compliant (Cannot run across multiple MPI ranks)
- Ariel Element (Ivy Bridge Feature) does not run on OSX
- Ariel Element (Sandy Bridge Feature) does not run on OSX
- Ariel Element (Sandy Bridge Feature) is not multi-core compliant (Cannot run across multiple MPI ranks)
- Miranda Element (SingleStream Feature) is not multi-core compliant (Cannot run across multiple MPI ranks)
- Miranda Element (RandomGen Feature) is not multi-core compliant (Cannot run across multiple MPI ranks)
- Sirius Element (Zodiac 27 Feature) does not support serialization
