PowSyBl HPC

PowSyBl (Power System Blocks) is an open source framework written in Java, that makes it easy to write complex software for power systems’ simulations and analysis. Its modular approach allows developers to extend or customize its features.

PowSyBl is part of the LF Energy Foundation, a project of The Linux Foundation that supports open source innovation projects within the energy and electricity sectors.

Environment requirements

The project contains both Java and C++ modules. If you are only interested in the Slurm computation manager, you can build the Java part only. If you're also interested in the MPI computation manager, you need to compiler C++ modules also.

To build the Java modules, you need the following requirements:

• JDK (17 or greater)
• Maven (3.8.0 or greater)

$> yum install java-17-openjdk maven 

To build the C++ modules, you need the additional requirements:

• CMake (2.6 or greater)
• A recent C++ compiler (GNU g++ or Clang)
• OpenMPI (1.8.3 or greater)
• Some development packages (zlib, bzip2)

$> yum install bzip2 bzip2-devel cmake gcc-c++ make wget zlib-devel

OpenMPI

In order to support the MPI modules, you need to compile and install the OpenMPI library.

$> wget https://download.open-mpi.org/release/open-mpi/v1.8/openmpi-1.8.3.tar.bz2
$> tar xjf openmpi-1.8.3.tar.bz2
$> cd openmpi-1.8.3
$> ./configure --prefix=<INSTALL_DIR> --enable-mpi-thread-multiple
$> make install
$> export PATH=$PATH:<INSTALL_DIR>/bin
$> export LD_LIBRARY_PATH=<INSTALL_DIR>/lib:$LD_LIBRARY_PATH

Build

Simple Java Build

If you're interested in the Slurm computation manager only, you can easily compile the project using the following command:

$> mvn package

Full Build

We provide a toolchain to help people to build this project. This toolchain downloads thirdparties (boost, libarchive, log4cpp, protobuf) from the Intenet, compiles both Java and C++ modules and create an iTools distribution. It's a standalone external folder that contains all the built objects required to run powsybl programs through the itools command-line interface. This repository contains the install.sh script to do so easily. By default, the install.sh will download dependencies from the Internet, compile code and finally copy the resulting iTools distribution to the install folder.

$> ./install.sh

This will run both the C++ build and the java build and copy their results to the install folder.

A more detailled description of the install.sh script options follows:

Targets

Target	Description
clean	Clean modules
clean-thirdparty	Clean the thirdparty libraries
compile	Compile modules
package	Compile modules and create a distributable package
install	Compile modules and install it
docs	Generate the documentation (Doxygen/Javadoc)
help	Display this help

Options

The install.sh script options are saved in the install.cfg configuration file. This configuration file is loaded and updated each time you use the install.sh script.

Global options
