Oh yes, my mistake I misinterpreted the error message. It is actually the nvcc compiler complaining about multiple command line arguments related to optimization (which it is really picky about even if the two arguments are identical.) I reformatted some of the configure output to show this
-ccbin mpicxx -std=c++14 -Xcompiler -fPIC -O3 -gencode arch=compute_75,code=sm_75 -Wno-deprecated-gpu-targets -I/usr/lib/x86_64-linux-gnu/openmpi/include/openmpi -I/usr/lib/x86_64-linux-gnu/openmpi/include -DDEBUGlevel=0 -DPRNTlevel=0 the next fragment is -O3 -DNDEBUG --generate-code=arch=compute_75,code=[compute_75,sm_75] -Xcompiler=-fPIC -std=c++11 -x cu -rdc=true -c /home/blahblah/Projects/220824-petsc-example-for_forum/petsc/arch-linux-c-opt/externalpackages/git.superlu_dist/SRC/superlu_gpu_utils.cu -o Hence the -O3 appears twice, once from the CMAKE argument PETSc passes to superlu_dist -DCMAKE_CUDA_FLAGS=" -ccbin mpicxx -std=c++14 -Xcompiler -fPIC -O3 -gencode arch=compute_75,code=sm_75 -Wno-deprecated-gpu-targets -I/usr/lib/x86_64-linux-gnu/openmpi/include/openmpi -I/usr/lib/x86_64-linux-gnu/openmpi/include -DDEBUGlevel=0 -DPRNTlevel=0" and then presumably, the superlu_dist cmake process adds its own arguments which overlap. If I remember correctly this is fixed in the main branch of PETSc, could you do an identical build with the main branch? If that works we will just need to figure out how to get MOOSE to work with main PETSc branch. Barry Sadly each one makes different -std=c++11 vs -std=c++14 choices as well. -------------------- [ 15%] Building CUDA object SRC/CMakeFiles/superlu_dist.dir/superlu_gpu_utils.cu.o cd /home/blahblah/Projects/220824-petsc-example-for_forum/petsc/arch-linux-c-opt/externalpackages/git.superlu_dist/petsc-build/SRC && /usr/bin/nvcc -DSUPERLU_DIST_EXPORTS -Dsuperlu_dist_EXPORTS -I/home/blahblah/Projects/220824-petsc-example-for_forum/petsc/arch-linux-c-opt/externalpackages/git.superlu_dist/petsc-build/SRC -I/home/blahblah/Projects/220824-petsc-build/installation/include -I/usr/lib/x86_64-linux-gnu/openmpi/lib -DUSE_VENDOR_BLAS -ccbin mpicxx -std=c++14 -Xcompiler -fPIC -O3 -gencode arch=compute_75,code=sm_75 -Wno-deprecated-gpu-targets -I/usr/lib/x86_64-linux-gnu/openmpi/include/openmpi -I/usr/lib/x86_64-linux-gnu/openmpi/include -DDEBUGlevel=0 -DPRNTlevel=0 -O3 -DNDEBUG --generate-code=arch=compute_75,code=[compute_75,sm_75] -Xcompiler=-fPIC -std=c++11 -x cu -rdc=true -c /home/blahblah/Projects/220824-petsc-example-for_forum/petsc/arch-linux-c-opt/externalpackages/git.superlu_dist/SRC/superlu_gpu_utils.cu -o CMakeFiles/superlu_dist.dir/superlu_gpu_utils.cu > On Aug 25, 2022, at 9:38 AM, byron <lbgpub...@gmail.com> wrote: > > Hi Barry > > There doesn't appear to be any reference to 'optimize' in the only copy of > superlu_gpu_utils.cu <http://superlu_gpu_utils.cu/> I could find, I've > attached a copy. > > Thanks > > > > On Thu, Aug 25, 2022 at 1:44 PM Barry Smith <bsm...@petsc.dev > <mailto:bsm...@petsc.dev>> wrote: > > nvcc fatal : redefinition of argument 'optimize' > make[2]: *** [SRC/CMakeFiles/superlu_dist.dir/build.make:499: > SRC/CMakeFiles/superlu_dist.dir/superlu_gpu_utils.cu.o] Error 1 > make[2]: *** Waiting for unfinished jobs.... > nvcc fatal : redefinition of argument 'optimize' > make[2]: *** [SRC/CMakeFiles/superlu_dist-static.dir/build.make:499: > SRC/CMakeFiles/superlu_dist-static.dir/superlu_gpu_utils.cu.o] Error 1 > make[2]: *** Waiting for unfinished jobs.... > > It seems that nvcc is unhappy with something in superlu_gpu_utils.cu > <http://superlu_gpu_utils.cu/> Could you check that file for any > "redefinition of optimize"?
