 ====== Which parts of CP2K are CUDA-accelerated? ======
-  * FFTs, when compiled with ''%%-D__PW_CUDA%%''
+Have a look at our [[:gpu | GPU page]] as well as [[howto:compile_with_cuda | this howto ]].
-  * Anything that uses ''dbcsr_multiply'', i.e. sparse matrix multiplication, when compiled with ''%%-D__DBCSR_CUDA%%''. This benfits in particular the [[linear scaling DFT]] code.
-  * If linked against an accelerated scalapack/blas library (in particular pdgemm/dgemm) that executes these calls on the GPU. The impact of this is most visible for MP2 and RPA calculations. On the hybrid Cray XC30 linking against libsci_acc makes this happen.
