<div dir="ltr">Hi all,
<div><br></div><div>I have implemented a problem of coupled diffusion equations in 1D using PETSc. I was able to configure PETSC with and without MPI. The code runs well in both cases.</div><div><br></div><div>Now I would like to test CUDA but I am unable to configure it. I get an error message related to thrust directory.</div>
<div><br></div><div>The options I use to configure are the following:</div><div><br></div><div>--with-x=1 --with-mpi=0 --with-cc=icc --with-cxx=icpc --with-clanguage=cxx --with-fc=ifort --with-cuda=1 --with-cuda-dir=/usr/local/cuda-6.0 --with-cuda-arch=sm_35 --with-cudac=/usr/local/cuda/bin/nvcc --with-thrust=1 --with-thrust-dir=/usr/local/cuda-6.0/include/thrust --with-cusp=1 --with-cusp-dir=/usr/local/cuda-6.0/include/cusp --download-txpetscgpu=1 --with-debugging=1 --with-scalar-type=real --with-precision=double --download-f-blas-lapack<br>
</div><div><br></div><div>The error message I get is:</div><div><br></div><div><div>===============================================================================</div><div>             Configuring PETSc to compile on your system                       </div>
