Welcome to the RAJA Portability Suite tutorial series. In this repo, you will find a set of tutorials. This set includes an introductory tutorial which will provide guided set of lessons to follow to learn how to get started with the RAJA Portability Suite. The set also includes a more advanced (i.e. Intermediate) tutorial meant for those who would like more hands-on instruction for RAJA. We would suggest starting with the Intro tutorial and then moving on to the Intermediate tutorial.
If you are running on an LC machine and would like to build locally, be sure to do the following to build and run the tutorials:
module load cmake/3.23.1
module load gcc/8.3.1
module load cuda/11.2.0
cmake -DENABLE_CUDA=On -DENABLE_OPENMP=Off -DCMAKE_CUDA_ARCHITECTURES=70 -DCMAKE_CUDA_COMPILER=/usr/tce/packages/cuda/cuda-11.2.0/bin/nvcc -DCUDA_TOOLKIT_ROOT_DIR=/usr/tce/packages/cuda/cuda-11.2.0 -DBLT_CXX_STD=c++14 -DCMAKE_BUILD_TYPE=Release -DRAJA_ENABLE_EXERCISES=On -DRAJA_ENABLE_OPENMP=Off -DCMAKE_CUDA_FLAGS=--extended-lambda -DCUDA_ARCH=sm_70 ../
(Note: you need a cmake version greater or equal than 3.23.1 and you need a more
recent gcc version which can handle c++14. For example, on the Lassen LC machine a cmake command like cmake -DBLT_CXX_STD=c++14 -DCMAKE_CUDA_ARCHITECTURES=70 -DENABLE_CUDA=On -DCMAKE_CUDA_FLAGS="--expt-extended-lambda" ../ after loading appropriate cmake and gcc modules will work well.)
