Cyclus 1.4.0

Cyclus 1.4.0 Release

Author: Cyclus Developers

Contact: https://groups.google.com/forum/#!forum/cyclus-dev

The Cyclus core team is excited to announce the latest stable version of the
Cyclus ecosystem!

Major Features

Compatibility:

• C++ 11 support is now required to compile Cyclus and Cycamore.
• Resource exchange preferences now default to 1.0 instead of zero.

Cyclus

Features:

• Resource exchange now supports COIN linear and mixed integer linear solvers.
  This can be specified in the input file.
• Added new optional :ref:ExplicitInventory <explicit-inv-table> and
  :ref:ExplicitInventoryCompact <explicit-inv-compact-table> tables to the
  database that can be enabled via input file.
• Implemented custom time step duration that can be set in the input
  file (i.e. CEP 23).
• Agents/archetypes now can provide their own versions that are recorded in
  the :ref:AgentVersion <agent-version-table> table in the database for
  provenance/reproducibility.
• Support for new datatypes added to the sqlite backend:
  • std::list<std::pair<int, int> >
  • std::map<std::string, std::pair<std::string, std::vector<double> > >
• cycpp now supports the internal annotation for state variables
  allowing them to be persisted in the database, but not visible in the input
  file or GUI.
• Adding 2 new variables allowing to adjust the caculation tolerance:
  tolerance_generic and tolerance_generivc.

Bug fixes:

• Fixed floating-point comparison bugs in DRE causing incorrectly failed
  resource trades.
• Determinism/reproducibility improved by calling agents' resource exchange
  related functions in consistent order.
• Fixed invalid memory access bugs affecting newer and mac compilers.
• xinclude substitutions in input files are now processed for the input file
  stored in output databases - rather than storing the incomplete, partial
  input file.
• Archetype compilation now correctly fails early if the cycpp
  preprocessor fails.
• Fix late silent failures on <= 0.0 quantity bids to early loud failures.
• cyclus::toolkit::ResBuf is no longer experimental.

Since v1.3.0,

The Cyclus core team is excited to announce the latest stable version of the
cyclus ecosystem!

Major features

Cyclus

• ~3x speedups for recipe-based simulations
• Basic inventory policies added
• Support for recursive containers in archetypes
• Many new recursive containers added to sqlite backend
• Regression tests run on macs!
• A MockSim interface for full simulation testing without input files
• Added customizeable TimeSeries output for recording archetype-specific time
  series
• Added json-to-xml conversion capability
• Added new ResMap container
• Decay added (via Pyne)! An input file flag can be set to
  • never: never decay
  • manual: archetypes must call the decay API manually
  • lazy: materials are decayed as needed when their Material::comp function is
    called

Cycamore

• New facility archetypes added
  • Reactor
  • FuelFab
  • Separations
  • Enrichment
• Other facility archetypes removed
  • BatchReactor
  • EnrichmentFacility
• Some experimental archetype APIs updated
  • GrowthRegion
• Much better end-of-life fuel handling in reactors
• Regression tests run on macs!

Cymetric

• First release for a new analysis and visualization tool for Cyclus simulation output
• Command line tool and Python interface
• Calculates metrics of user interest from a Cyclus database
  • Writes metrics back to database
  • Simple for users to extend the suite of metrics
    • Designed so calculations can be based on dependencies (other metrics or root metrics)
    • Uses pandas data types
  • Uses PyNE for nuclear data
• Visualization available from the command line via matplotlib
