[petsc-dev] PETSc with CUDA without CUSP

[Daniel Lowell]

Is there a way to configure PETSc to build with nvcc CUDA support, but
without the CUSP flags being set? I'd like to set up PETSc independent of
any CUSP flags or MACROs.

Default, any configuration settings require you specify CUSP and THRUST
support.

Here is my current configuration file:

CFLG="--CFLAGS=-O2 -fopenmp -msse2 -mfpmath=sse -g -ggdb"
FFLG="--FFLAGS=-O2 -fopenmp -g"
WCC="--with-cc=gcc"
MPI_DIR="--with-mpi-dir=$MPICH2_HOME"
WBL="--with-blas-lapack-dir=$INTEL_MKL"
LAD="--download-c-blas-lapack=yes --download-f-blas-lapack=yes"
HYP="--download-hypre=1"
HDF="--with-hdf5=1 --download-hdf5=1"
CUD="--with-cuda-dir=/soft/cuda-4.0/cuda"
USP="--with-thrust-dir=/soft/cuda-4.0/cuda/include
--with-cusp-dir=/soft/cuda-4.0/cuda/include"


./config/configure.py $MPI_DIR $LAD $CFLG $FFLG $HYP $HDF $CUD \
--with-cudac="nvcc -m64" \
--with-precision=double \
--with-clanguage=c \
--with-cuda-arch=sm_20 \
PETSC_ARCH=structgrid_cuda



Note my USP flag is not included in the configuration invocation.



Thanks,

Daniel Lowell
