Summary

Makefile based build processes are described below.

CMake build (recommended)

setup your environment

On SCOREC RHEL7 one possible configuration is:

module load gcc mpich cmake cuda/10.2

configure and build

cmake -S ./egads -B buildEGLcuda -DCMAKE_CUDA_ARCHITECTURES=75 -DCMAKE_INSTALL_PREFIX=$PWD/buildEGLcuda/install
cmake --build buildEGLcuda --target install -j8

debug build

cmake -S ./egads -B buildEGLcudaDbg -DCMAKE_BUILD_TYPE=Debug -DCMAKE_CUDA_FLAGS_DEBUG="-g -G" -DCMAKE_CUDA_ARCHITECTURES=75 -DCMAKE_INSTALL_PREFIX=$PWD/buildEGLcudaDbg/install
cmake --build buildEGLcudaDbg --target install -j8

Makefile build

setup your environment

On SCOREC RHEL7 one possible configuration is:

module load gcc mpich cmake cuda/10.2

configure

cd config
./makeEnv /path/to/openCascade/install
cd ../
#edit ESPenv.sh and replace LINUX64 with LINUX64_cuda
source ESPenv.sh
#edit include/LINUX64_cuda and set the appropriate cuda architecture flag for your system (currently set to sm_75)

Note, the opencascade install is not used, but the makeEnv script requires it, AFAIK.

build egadslite

cd lite
make -f Makefile.cuda clean
make -f Makefile.cuda

build liteTest

make -f liteTestCuda.make clean
make -f liteTestCuda.make

run liteTest

Expected output from liteTest (host build)

$ ../bin/liteTest.host ../examples/box.egadslite 
 EG_open          = 0
 EG_loadModel     = 0  ../examples/box.egadslite

    Attr: _tParams = 1.099854 0.043994 15.000000

Executing liteTestCuda currently produces the following output:
