HELICS v2.5.0 Release Notes

Release Date: 2020-04-26 // almost 4 years ago

  • ⚡️ Some library reorganization, additional static analysis(CppLint and clang-tidy), multiBroker, updates to the webserver including some new capabilities for creating and destroying brokers.

    Note: the helics_broker has a bug when using the implicit default core type; as a temporary workaround either run it with the --coretype argument or use the helics_app broker subcommand.

    🔄 Changed

    • Split the HELICS core library into a separate core and network library
    • ⚡️ Update FMT library to version 6.2.0
    • 🛠 The core and broker Factories use a map instead of a fixed list which is a step toward allowing user defined cores
    • ⚡️ Updated CLI11 included code to customized version to allow configuration of cores and brokers through Json files
    • The ordering of the helics_error_types enum is in ascending order
    • 🔨 Refactored the Matlab and Java swig interface builds to enable standalone builds

    🛠 Fixed

    • ➕ Added CPPlint and fixed a number of issues that check identified.

    ➕ Added

    • helicsEndpointSendMessageObjectZeroCopy to allow transferring messages with minimal copying.
    • helics<Interface>IsValid functions to the C API
    • helicscpp::cleanHelicsLibrary to the C++98 API.
    • A Comm factory to the Core to enable constructing Comm interfaces directly from the type.
    • ⚡️ The REST API in the webserver was updated to include ability to create and destroy brokers.
    • A websocket server similar to the REST API but will respond to JSON queries.
    • ✅ A test suite for the HTTP and websocket servers.
    • A Multibroker that can allow multiple communication types to interact together.
    • 🏗 Support for HELICS_BUILD_CONFIGURATION cmake variable for building on unique platforms. The only supported one right now is "PI" for building on raspberry pi platforms.
