Release: 0.13.0

[ax3l]

Streaming Support, Python, Benchmarks

This release adds first support for streaming I/O via ADIOS2's SST engine. More I/O benchmarks have been added with realistic application load patterns. Many Python properties for openPMD attributes have been modernized, with slight breaking changes in Iteration and Mesh data order. This release requires C++14 and adds support for Python 3.9. With this release, we leave the "alpha" phase of the software and declare "beta" status.

Thanks to @ax3l, @franzpoeschel, @guj, @PrometheusPi, and @sbastrakov for contributing to this release!

Which version am I running?

Python

import openpmd_api
print(openpmd_api.__version__)

C++

#include <openPMD/openPMD.hpp>
#include <iostream>

int main() {
    // query compile-time macros:
    std::cout << OPENPMDAPI_VERSION_MAJOR << "."
              << OPENPMDAPI_VERSION_MINOR << "."
              << OPENPMDAPI_VERSION_PATCH << std::endl;
    // there is also: OPENPMDAPI_VERSION_LABEL (e.g. "alpha")

    // or query the runtime API (since 0.12.0):
    std::cout << openPMD::getVersion() << std::endl;
    return 0;
}

CLI

# command line option (since 0.12.0):

We will address one more bug (#856/#862) before cutting the release.
