A simple tutorial on how to build and run libROM. For more details, see the README file.

In addition to the native build system described below, libROM packages are also available in Spack:

• Spack

Clone libROM

• https://github.com/LLNL/libROM

Installation

To compile libROM with default build settings (Mac and LLNL LC Machines):

 ./scripts/compile.sh

To compile libROM for Ardra (LLNL LC Machines only):

./scripts/ardra_compile.sh

To compile libROM using a different toolchain within cmake/toolchains (Mac and LLNL LC Machines):

./scripts/toolchain_compile.sh toolchain.cmake

Compilation options:

• -a: Compile a special build for the LLNL codebase: Ardra
• -d: Compile in debug mode.
• -m: Compile with MFEM (required to run the libROM examples)
• -t: Use your own cmake/toolchain
• -u: Update all of libROM's dependencies.

Compiling on LC Machines

libROM provides several CMake toolchains which can be used to compile on LLNL LC machines. For more information on installing and using libROM on specific LC machines, refer to the libROM wiki page.
