 +
 +infatti i file.cu vengono compilati con [[neurali:nvcc]] invece che gcc, ma come spiegato, qui devono essere separati i due codici...

 +>> host_config.h file you mentioned.
 +
 +**Allora**
 +
 +per **non** usare CUDA, NVCC, ecc,.. commentare riga 14 ./src/nemo/config.h.in
 +
 +  /*#cmakedefine NEMO_CUDA_ENABLED*/
 +
 +Inoltre commentare anche riga 260 e 238 e 456 ./build/CMakeCache.txt:

 +A questo punto NeMo risulta compilato, ma senza CUDA
 +
 +poi pero' spikestream non funziona se NeMo non fornisce CUDA
