ExaWind Builder is a collection of bash scripts to configure and compile the codes used within the ExaWind project on various high-performance computing (HPC) systems. The builder provides the following
-
Platform configuration: Provides the minimal set of modules that must be loaded when compiling with different compilers and MPI libraries on different HPC systems.
-
Software configuration: Provides baseline CMake configuration that can be used to configure the various options when building a project, e.g., enable/disable optional modules, automate specification of paths to various libraries, configure release vs. debug builds.
-
Build script generation: Generates an executable end-user script for a combination of system, compiler, and project.
-
Exawind environment generation: Generates a source-able, platform-specific script that allows the user to recreate the exact environment used to build the codes during runtime.
The build scripts are intended for developers who might want to compile the codes with different configuration options, build different branches during their development cycle, or link to a different development version of a library that is currently not available in the standard installation on the system. Please see the documentation for details on how to use this to build ExaWind software.
ExaWind Builder is already installed and setup on OLCF Summit, NREL Eagle/Rhodes, and NERSC Cori systems. On these systems, you can proceed directly to using build scripts from the central installation. Please consult user manual to learn how to use the scripts.
ExaWind builder has pre-built
configurations
for several systems. On these systems you can use the bootstrap script to
quickly get up and running. Please consult installation
manual. The
relevant steps are shown below.
# Download bootstrap script
curl -fsSL -o bootstrap.sh https://raw.githubusercontent.com/exawind/exawind-builder/master/bootstrap.sh
# Make it executable
chmod a+x bootstrap.sh
# Execute bootstrap and provide system/compiler combination
./bootstrap.sh -s [SYSTEM] -c [COMPILER]
# Examples
./bootstrap.sh -s spack -c clang # On MacOS with homebrew
./bootstrap.sh -s ornl-summit -c gcc $ Oakridge Summit system
./bootstrap.sh -s eagle -c gcc # NREL Eagle
./bootstrap.sh -s cori -c intel # NERSC Cori
./bootstrap.sh -s snl-ascicgpu -c gcc # SNL GPU development machineYou can add new system definitions to exawind-builder for use on new systems that are not used by ExaWind team. Please see manual installation and adding a new system sections in the user manual.
