C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v12.2\include\cublas_v2.h(59): fatal error C1189: #error: "It is an error to include both cublas.h and cublas_v2.h"
Due to the clear error message, I think more information is not needed, just ask me if you need any more.
When I ran this code. i realize that the sum of vector of cpu method and reduceAtomicGlobal method are difference from another method if N > 16'777'217
.
And of course the sum of vector is wrong.
Can you help me point out why It hapen.
You can see my console log.
The Expected value
is not 42e9
because I fill each element in vector vals
is 1.0f
Expected value: 1e+09
BFD: /lib/x86_64-linux-gnu/libutil.so.1: unknown type [0x13] section `.relr.dyn'
