SST V13.1.0 Release Notes
Fixed issues and significant code changes:

Deprecation and Removal Notices

The Simulation class has been deprecated as a public API and will be removed in SST 14, which has the following impacts:
- simulation.h has been deprecated and will be removed in SST 14
- BaseComponent::getSimulation() is deprecated and will be removed from public APIs in SST 14. Elements should use functions directly available through the Component/SubComponent/etc. APIs instead.
sendInitData() and recvInitData() have been deprecated in both the Link and SimpleNetwork APIs. Equivalent functions sendUntimedData and recvUntimedData should be used instead.
The transition to requiring Modules to register the Module API they implement is complete. The SST_ELI_REGISTER_MODULE macro now requires an API class name and should be used to register modules. The temporary SST_ELI_REGISTER_MODULE_DERIVED macro is deprecated. The transition to requiring SubComponents to register the SubComponent API they implement is complete. The SST_ELI_REGISTER_SUBCOMPONENT macro should be used to register subcomponents and the temporary SST_ELI_REGISTER_SUBCOMPONENT_DERIVED macro is deprecated.

SST-Core

Fixed bug where command line arguments were not overriding input file options
Fixed bug in StatisticGroup::containsStatistic
Added string formatting aliases for SimTime_t, StandardMem::Addr, SimpleNetwork::nid_t
Fixed an issue in SST_ELI_DECLARE_NEW_BASE when BuilderInfo is a dependent name
General clean up in configure including removing unused macros and some references to Python2
KNOWN ISSUE: With XCode 14.3+, the sst-test-core testsuites will fail due to minor changes in floating point math causing floating point statistics to diff. A workaround is to compile with -ffp-contract=off and this has been implemented in the release branch and tar files when compiling on OSX.
CMake clean up
Fixed bug where elements would not be unregistered correctly using sst-register -u
Change to allow debug flags like -g3 or -ggdb3 in addition to bare -g
Added extended help capability for command line options using sst --help=option. Added extended help for --enable-profiling. Added linting for CMake files

SST-Elements

Element directories that started with a capital letter have been renamed to camelcase or lowercase. See element-specific release notes for details.
Minor fixes for compiler warnings in several element libraries
Build system cleanup to remove references to unused libraries
ariel
- Remove unsupported macOS pintool compilation code from Makefile
- Added missing include in ariel_shmem.h
cramSim
- Both the source code directory and library name have been renamed to ‘cramSim’ from ‘CramSim’. Input scripts need to be updated.
ember
- Removed workaround for firefly MPI bug as that has been resolved.
- Extended the available patterns in the trafficgen motif
- Fixed issue where OTF2 was not building
- Fixed null request bug
firefly
- Fixed bug in MPI
- Added missing parameters in pyfirefly
memHierarchy
- Fixed a number of issues with LL/SC instructions including adding support for SMT threads using LL/SC and resolving bugs that led to lockup.
- LoadLink is now a GetSX (read-for-ownership) instead of a GetS (read)
- Fixed a memory leak in MemRtrEvent that occurred in serialization.
- The header file ‘simpleMemHMCExtension.h’ was removed. The same functionality is supported under the StandardMem interface.
mercury
- Added testing
merlin
- Fixed bug in getting attributes in TemplateBase when there is a passthrough object
- Fixed bug with the Bridge not ending up in the libmerlin ELI
- Added topology model for Polarstar and Polarfly
messier
- The source code directory has been renamed to ‘messier’ from ‘Messier’. The library has not yet been renamed.
mmu
- Added support for accepting a remote TLB flush instruction
rdmaNic
- In conjunction with Vanadis, the rdmaNic has been enhanced to support MPI applications
samba
- The source code directory has been renamed to ‘samba’ from ‘Samba’. The library has not yet been renamed.
- Many source code files were also renamed to use lowercase
vanadis
- In conjunction with the rdmaNic, both MIPS and RISCV pipelines now support MPI applications
- The order in which pipeline stages are executed was changed so that Retire occurs prior to the other stages. This fixed a significant bug.
- The ELI for parameters was updated to reflect current parameter options
- Testing added for fread, fwrite, and lseek
- RISCV decoder support added for FCVT.S.LU, FCVT.W.S, FEQ.S
- Fixed a bug caused by LL/SC instructions with SMT in the load-store queue
- Fixed bug where Vanadis could attempt to execute a syscall for an ended process
- Fixed bug in jump (JLR) where immediate was not added
- Corrected MMIO device mapping
vaultsim
- The source code directory has been renamed to ‘vaultsim’ from ‘VaultSimC’. Additionally, the library has been renamed to ‘vaultsim’. Input scripts need to be updated.
