OPS is an API with associated libraries and pre-processors to generate parallel executables for applications on mulit-block structured grids. This repository contains the implementation of the run-time library and the pre-processor, and is structured as follows: | `- ops: Implementation of the user and run-time OPS C/C++ APIs | `- apps: Application examples in C and Fortran | These are examples of user application code and also include | the target code an OPS pre-processor should produce to correctly | use the OPS run-time library. | `- translator: Python OPS pre-processor for C/C++ API | `- doc: Documentation Installation ============ 1. Set up environmental variables: OPS_COMPILER - compiler to be used (Currently supports Intel, PGI and Cray compilers, but others can be easily incorporated by extending the Makefiles used in step 2 and 3) OPS_INSTALL_PATH - Installation directory of OPS/ops CUDA_INSTALL_PATH - Installation directory of CUDA, usually /usr/local/cuda (to build CUDA libs and applications) OPENCL_INSTALL_PATH - Installation directory of OpenCL, usually /usr/local/cuda for NVIDIA OpenCL implementation (to build OpenCL libs and applications) MPI_INSTALL_PATH - Installation directory of MPI (to build MPI based distributed memory libs and applications) HDF5_INSTALL_PATH - Installation directory of HDF5 (to support HDF5 based File I/O) See example scripts (e.g. source_intel, source_pgi_15.10, source_cray) under OPS/ops/ that sets up the environment for building with various compilers (Intel, PGI, Cray). 2. Build OPS back-end libraries. For C/C++ back-end use Makefile under OPS/ops/c (modify Makefile if required). The libraries will be built in OPS/ops/c/lib cd $OPS_INSTALL_PATH/c make For Fortran back-end use Makefile under OPS/ops/fortran (modify Makefile if required). The libraries will be built in OPS/ops/fortran/lib cd $OPS_INSTALL_PATH/fortran make 3. Build OPS example applications For example to build CloverLeaf_3D under OPS/apps/c/CloverLeaf_3D cd ../apps/c/Cloverleaf_3D/ make How to cite =========== Istvan Z Reguly, G.R Mudalige, Mike B Giles.
