Code execution on CUDA/CPU


Code execution on CUDA/CPU

Hope this helps Is there any way to find out in the __host__ __device__ function code is executed on CUDA or on CPU? , I interpreted your question as:
code :
__host__ __device__ void yourfunction() {
  #ifdef __CUDACC__
     // Device code branch
  #else
     // Host code branch
  #endif
}

it helps some times The CUDA C/C++ compiler should obey the language requirements in this respect.
Specifically, the language requirements as far as order-of-operation and short-circuiting should be maintained for non-overloaded || and && operators.

With these it helps
will any memory bound application benefit from high memory throughput of tesla(cc2.0) more than high number of cuda cores of geforce (cc5.0)?

To fix this issue You could try using openMP. Something like
All CUDA devices are used for display: Can not debug my CUDA-code from within desktop environment

I hope this helps you . In devices with compute capability of at least SM35, we can apparently get around this by setting the environment variable
Are there any in built CUDA functions which allows a CUDA kernel to report error to the host code?

it should still fix some issue CUDA has assertion support on all curently supported hardware (sm_20 and newer). As per the documentation, it is legal to do something like this:
