To build Neko, you will need a Fortran compiler supporting the Fortran-08 standard, autotools, pkg-config, a working MPI installation supporting the Fortran 2008 bindings (mpi_f08), BLAS/LAPACK and JSON-Fortran. Detailed installation instructions can be found in the Neko manual.
Sample build script:
| Code Block |
|---|
#!/bin/bash
export MPIFC=mpif90
export CC=mpicc
export FC=$MPIFC
export PKG_CONFIG_PATH=/path/to/jsonfortran/lib/pkgconfig:${PKG_CONFIG_PATH}
./regen.sh
./configure --prefix=<path>
make
make install |
...
To compile Neko with GPU support, please follow either the instructions in the manual (Compiling Neko for NVIDIA GPUs and Compiling Neko for AMD GPUs).
Note: A Neko installation can only support one backend. Thus, to run both CPU and GPU experiments, two different builds and installations are necessary.
...
Note: You are allowed to experiment with different linear solvers in Neko (see the manual) to achieve the fastest runtime. However, all of them are not guaranteed to work for the given case or support all hardware backends in Neko.
