Dynaflow-launcher

Dynaflow-launcher is a utility tool used to easily run Dynaflow starting from a minimal set of inputs.

It provides the following possibilities:

• Unitary simulations: computation of the steady-state solution on a given network (IIDM format) with Dynaflow;
• Systematic analysis: assessment of the stability of a single base network subject to different events;

Dynaflow-launcher depends on the core dynawo libraries of Dynaωo and Dynaωo algorithms.

Get involved!

Dynaflow-launcher is an open-source project and as such, questions, discussions, feedbacks and more generally any form of contribution are very welcome and greatly appreciated! For further informations about contributing guidelines, please refers to the contributing documentation.

Dynaflow-launcher Distribution

You can download a pre-built Dynaflow-launcher release to start testing it. Pre-built releases are available for Linux and Windows:

• Linux
• Windows

Linux Requirements for Distribution

• Compilers: C and C++ (gcc or clang), C++11 compatible for C++ standard
• Python2 or Python3
• Binary utilities: curl and unzip
• CMake

Note For Python you need to have the python command available in your PATH. If you don't have one, you can use an environment variable to point to your Python version with export DYNAWO_PYTHON_COMMAND="python3".

You can install the dependencies for Ubuntu or Fedora with:

$> apt install -y g++ unzip curl python
$> dnf install -y gcc-c++ unzip curl python

Windows Requirements for Distribution

• Runtime to be installed as administrator Microsoft MPI v10.1.2

> msmpisetup

Using a distribution

Linux

You can launch the following commands to download and test the latest distribution:

$> curl -L $(curl -s -L -X GET https://github.com/gitapi/repos/dynawo/dynaflow-launcher/releases/latest | grep "DynaFlowLauncher_Linux" | grep url | cut -d '"' -f 4) -o DynaflowLauncher_Linux_latest.zip
$> unzip DynaflowLauncher_Linux_latest.zip
$> cd dynaflow-launcher
$> ./dynaflow-launcher.sh help

Windows

Download the zip of the distribution and unzip it somewhere. Then open either Command Prompt or x64 Native Tools Command Prompt for VS2019 and use cd to go into the directory you previously unzipped. You should see a dynaflow-launcher.cmd file at the top of the folder. You can then launch:

> dynaflow-launcher help

Building Dynaflow-launcher on Linux

Dynaωo deploy

To build Dynaflow-launcher, you must first deploy the Dynaωo library.

$> ./myEnvDynawo.sh build-all
$> ./myEnvDynawo.sh deploy

This command creates a deploy folder in ${DYNAWO_HOME}. The path to dynawo deploy is then the path to the subdirectory dynawo in the deploy folder. It is generally similar to:

PATH_TO_DYNAWO_DEPLOY=${DYNAWO_HOME}/deploy/gcc8/shared/dynawo/

Dynaωo-algorithms deploy

The Dynaωo Algorithms library must also be deployed:

$> ./myEnvDynawoAlgorithms.sh build
$> ./myEnvDynawoAlgorithms.sh deploy

The latter command creates a deploy folder in ${DYNAWO_ALGORITHMS_HOME}. The path to dynawo-algorithms deploy is then the path to the subdirectory dynawo-algorithms in the deploy folder. It is generally similar to:

PATH_TO_DYNAWO_ALGORITHMS_DEPLOY=${DYNAWO_ALGORITHMS_HOME}/deploy/gcc8/dynawo-algorithms/

Dynaflow-launcher

To build Dynaflow-launcher you need to clone the repository and launch the following commands in the source code directory, it will create a myEnvDFL.sh file that will be your personal entrypoint to launch DFL and configure some options.

$> git clone https://github.com/dynawo/dynaflow-launcher
$> cd dynaflow-launcher
$> echo '#!/bin/bash

# Required
export DYNAFLOW_LAUNCHER_HOME=$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)
# Variables used to build Dynaflow-launcher
export DYNAWO_HOME=<PATH_TO_DYNAWO_DEPLOY>
export DYNAWO_ALGORITHMS_HOME=<PATH_TO_DYNAWO_ALGORITHMS_DEPLOY>
export DYNAFLOW_LAUNCHER_BUILD_TYPE=Release

# Optional
# export DYNAFLOW_LAUNCHER_LOCALE=en_GB
# export DYNAFLOW_LAUNCHER_CMAKE_GENERATOR=Ninja # default is Unix Makefiles
# export DYNAFLOW_LAUNCHER_PROCESSORS_USED=8 # default 1
# export DYNAFLOW_LAUNCHER_BUILD_TESTS=OFF # default ON
# export DYNAFLOW_LAUNCHER_LOG_LEVEL=INFO # default INFO: can be DEBUG, INFO, WARN, ERROR
# export DYNAFLOW_LAUNCHER_BROWER=firefox # browser command used to visualize test coverage. default: firefox

# Optional external links : optional variable used at runtime to use additional iidm extension
# export DYNAWO_IIDM_EXTENSION=<PATH_TO_IIDM_EXTENSIONS_LIBRARY>

# Run
$DYNAFLOW_LAUNCHER_HOME/scripts/envDFL.sh $@' > myEnvDFL.sh
$> chmod +x myEnvDFL.sh

Then update the path "PATH_TO_DYNAWO_DEPLOY" in the file to your deployed installation of Dynaωo, as well as the path "PATH_TO_DYNAWO_ALGORITHMS_DEPLOY", and then launch the following command:

$> ./myEnvDFL.sh build-user

All commands described in the rest of this README are accessible throught this script. To access all options of the script myEnvDFL.sh, type:

$> ./myEnvDFL.sh help

Build and use Dynaflow-launcher on Windows

Requirements

• SDK to be installed as administrator Microsoft MPI v10.1.2

> msmpisdk.msi

Build

Open x64 Native Tools Command Prompt for VS2019 and run the following commands (don't forget to adjust the path to the Dynaωo deploy folder in the DYNAWO_HOME define and the path to the Dynaωo-Algorithms deploy folder in the DYNAWO_ALGORITHMS_HOME define):

> git config --global core.eol lf
> git config --global core.autocrlf input
> md dynawo-project
> cd dynawo-project
> git clone https://github.com/dynawo/dynaflow-launcher
> cd dynaflow-launcher
> cmake -S . -B b -DUSE_MPI=YES -DCMAKE_INSTALL_PREFIX=../dfl-i -DDYNAWO_ALGORITHMS_HOME=../deploy/dynawo-algorithms -DDYNAWO_HOME=../deploy/dynawo -DDYNAFLOW_LAUNCHER_THIRD_PARTY_DIR=. -G "NMake Makefiles" -Wno-dev
> cmake --build b --target install

Warning We try to limit as far as possible the name of the build and install folders (for example dfl-i instead of dynaflow-launcher-install) because of Windows limitation of length of path for folders. We know it causes problems and the only solution is to install Dynaflow-launcher in a shorter length directory path.

Warning Only the build directory (b) can be located in the dynaflow-launcher folder, the install (dfl-i) folder should be located outside to avoid problems with CMake.

Command utility

A command file dynaflow-launcher.cmd (similar to myEnvDFL.sh or dynaflow-launcher.sh) is available:

• from build environment: use scripts\dynaflow-launcher
• from installation or deploy or distribution folder: use dynaflow-launcher

usage: dynaflow-launcher [VERBOSE] [DEBUG] [HELP | <command>]

HELP command displays this message.
Add VERBOSE option to echo environment variables used.
All commands are run in Release mode by default. Add DEBUG option to turn in Debug mode.

These are commands used by end-user:
  N   <network> <config>                              Run steady state simulation
  SA  <network> <config> <contingencies> [<nbprocs>]  Run systematic analysis
  NSA <network> <config> <contingencies> [<nbprocs>]  Run steady state simulation followed by systematic analysis
  version                                             Print dynaflowLauncher version

where <network> is the path of IIDM network file
      <config> is the path of DFL configuration file (JSON format)
      <contingencies> is the path of SA contingencies file (JSON format)
      <nbprocs> is the optional number of MPI processes to use for SA (default 1)

These are commands used by developer only:
  build [<install_dir>]           Build, install and deploy dynaflowLauncher
  [SHOW] tests [<unit_test>]      Build and run unit tests or a specific unit test (option SHOW lists available unit tests)
  clean                           Clean build directory

Not all options are available depending on whether the utility is run from the build environment or the installation/deployment/distribution folder.

The utility tries to guess some environment variables from context and set other to default values (please set it to another value if not correct):

  DYNAWO_HOME=<found_in_distribution_or_in_a_known_place_for_deployment>
  DYNAWO_USE_XSD_VALIDATION=false
  DYNAWO_ALGORITHMS_HOME=<found_in_distribution_or_in_a_known_place_for_deployment>
  DYNAFLOW_LAUNCHER_HOME=<found_in_a_known_place_for_building_environment>
  DYNAFLOW_LAUNCHER_LOCALE=en_GB
  DYNAFLOW_LAUNCHER_LOG_LEVEL=INFO
  DYNAWO_PYTHON_COMMAND=python

Then the utility automatically sets all other environment variables based on the commandline, above variables and context.

Run steady-state simulation

To run Dynaflow-launcher, you can use the script myEnvDFL.sh with the "launch" option:

$> ./myEnvDFL.sh launch <network> <config>

where network is the path to the network file (IIDM) and config the path to the configuration file.

Run systematic analysis

To run a systematic analysis with Dynaflow-launcher, you can use the script myEnvDFL.sh with the "launch-sa" option:

$> ./myEnvDFL.sh launch-sa <network> <config> <contingencies>

where network is the path to the network file (IIDM), config the path to the configuration file and contingencies the path to the contingency file (json).

Run steady-state simulation automatically followed by a systematic analysis

To run a steady-state simulation automatically followed by a systematic analysis with Dynaflow-launcher, you can use the script myEnvDFL.sh with the "launch-nsa" option:

$> ./myEnvDFL.sh launch-nsa <network> <config> <contingencies>

where network is the path to the network file (IIDM), config the path to the configuration file and contingencies the path to the contingency file (json).

Testing

Dynaflow-launcher testing relies on cmake tests.

You can use the script myEnvDFL.sh with the "tests" option. Dynaflow-launcher must be compiled.

$> ./myEnvDFL.sh tests

For MAIN and MAIN_SA unit tests, which are composed of complete Dynaωo simulations, reference tests can be updated using the script myEnvDFL.sh

$> ./myEnvDFL.sh update-references

Coverage

Coverage analysis is based on ctest. Outputs are gcov and lcov reports.

You can use the script myEnvDFL.sh with the "build-tests-coverage" option.

$> ./myEnvDFL.sh build-tests-coverage

Developement standard

Check style

The check style, based on Dynawo's, is based on a clang-format file using clang-format.

The check style is checked:

• before commiting. This check is performed by hooks. This hook is installed automatically when using the script myEnvDFL.sh with any option. The commit will be refused if formatting was not applied to the commited file.
• at compilation: coding style is applied on all modified files (git POV).

SCM

git commits have a standard pattern, similar to the one in Dynawo core. This pattern can be checked by hooks. This hook is installed automatically when using the script myEnvDFL.sh with any option.
