Hello,
I have a fairly straightforward application for CUDA BLAS, except for one thing; I need to do a piecewise hyperbolic tangent operation on a vector. This should be a trivial kernel to write (I’ve already written it), but integrating this kernel into my code has shown to be problematic.
Here’s where I am so far:
-I put the kernel code in a .cu file, within my project.
-I downloaded the custom build rule for CUDA, and made sure that MSVC associates that rule with the .cu file (it compiles without any problems).
-I added the following lines to my code:
#include <cutil.h>
global void tanhGPU(int size, float *vec); //forward declaration
Since I’m calling cublasInit(), I’m assuming that I don’t need to call CUT_DEVICE_INIT(). I can’t call it anyway, since the compiler complains about all sorts of stuff inside that macro.
Even if I leave it out, I still get the following error:
error C2059: syntax error : ‘<’
…Referencing the call to:
tanhGPU<<1, 32>>(32, test_D);
Any ideas as to what I’m doing wrong?
Thanks!
