HPAC-ML is a directive-based programming model that enables easy use of ML surrogate models in scientific applications. The programming model can invoke a model, replacing parts of an application with NN inference, or collect data during application execution to be used during offline training of ML models.
We recommend using or building the provided HPAC-ML container.
Otherwise, you can install the spack environment from spack.yaml.
To build the HPAC-ML compiler and runtime system execute the following commands:
git clone git@github.com:LLNL/HPAC.git
cd HPAC
./setup.sh 'PREFIX' 'NUM THREADS' The 'PREFIX' argument defines where to install all the HPAC related binaries and executables. The 'NUM THREADS' parameter define how many threads should the installation use. The installation script performs the following actions:
- Configures, builds and installs Clang/LLVM including the approximation extensions.
- Configures, builds and installs the approximation library.
- Creates a file, called 'hpac_env.sh', at the root of the project which should always be sourced before using HPAC.
The installation process can take a considerable amount of time. For quick exploration, we recommend
