Build and Compilation
SpecFWAT is built using CMake, a cross-platform build system. The following instructions will guide you through the process of building SpecFWAT on your system.
Create a build directory
mkdir build && cd buildConfigure the build
Bascially, you can use the following command to configure the build:
cmake ..More options
Specfiy the compiler
If you have multiple compilers installed, you can specify the Fortran and C compilers using the FC and CC options, respectively. For example on Niagara@CCDB:
CC=icc CXX=icpc FC=mpifort MPIFC=mpifort cmake ..Specfiy HDF5 library
If the HDF5 library is installed in a non-standard location, you can specify the path to the HDF5 library using the HDF5_ROOT option. For example:
cmake -DHDF5_ROOT=/path/to/hdf5 ..Enable GPU support
Currently, SpecFWAT only supports CUDA for GPU acceleration. The CUDA architecture can be specified using the CUDA_ARCH option. Check the table below for the supported architectures:
CUDA_ARCH | Architecture | Example |
|---|---|---|
| 0 | GPU on current machine | N/A |
| 4 | Tesla | K10, Geforce GTX 650 |
| 5 | Kepler | K20 |
| 6 | Kepler | K80 |
| 7 | Maxwell | Geforce GTX 750, Tesla M60 |
| 8 | Pascal | Geforce GTX 1080, Tesla P100 |
| 9 | Volta | Tesla V4 |
| 10 | Turing | Geforce RTX 2080, Tesla T4 |
| 11 | Ampere | Geforce RTX 3080, Tesla A100 |
| 12 | Hopper | Geforce RTX 4090, Tesla H100 |
For example, to enable CUDA support and set the architecture to Ampere (A100), you can use the following command:
cmake -DUSE_CUDA=on -DCUDA_ARCH=11 ..Compilation
After configuring the build, you can compile SpecFWAT using the following command:
make -j4
