[CIG-SEISMO] Error with running the solver with gpu

[Dimitri Komatitsch]

Hi,

Answer from Etienne Bachmann:

"I guess the error is due to the way we impose the architecture setting 
on GPU ==> relating the cuda version ( cuda, cuda5, cuda6 ... ) to the 
architecture (gencode 25 35 ...).
In the CUDA samples, they generate the code for each architecture 
regardless to the cuda version, we probably should do like that too.

A quick solution for this error is to comment out, in the 
./src/cuda/mesh_constants_cuda.h file, the flags :
#define USE_TEXTURES_FIELDS
#define USE_TEXTURES_CONSTANTS
