[petsc-dev] Intel compilers + CUDA

[John Fettig]

Unfortunately it doesn't work.  I'll send the logs to petsc-maint, but
here's the error.  If you remove these lines:

#ifndef PETSC_HAVE___INT64
#define PETSC_HAVE___INT64 1
#endif

from $PETSC_ARCH/include/petscconf.h, it builds ok (and make test passes).
Here's the error:

nvcc -O -arch=sm_20 -c --compiler-options=-fPIC
-I/home/jfe/local/petsc-dev/include
-I/home/jfe/local/petsc-dev/intel-opt-cuda-precise/include
-I/usr/local/cuda/include
-I/home/jfe/local/petsc-dev/intel-opt-cuda-precise/include/txpetscgpu/include
-I/usr/local/encap/platform_mpi-8.01/include
-D__INSDIR__=src/vec/vec/impls/seq/seqcusp/ veccusp.cu

"__int64" is undefined
