Hi All.
I am using GCC 4.5.4 with CUDA 4.1
I am getting this error:
terminate called after throwing an instance of 'thrust::system::system_error'
what(): synchronize: launch_closure_by_value: unspecified launch failure
This is my code
// .cu file
#include "ActivationFunctionTanh.hpp"
#include <cuda.h>
#include <cuda_runtime.h>
#include <thrust/device_ptr.h>
#include <thrust/transform.h>
struct tanh_func {
__device__
double operator() (double x) {
return tanh(x);
}
};
void ActivationFunctionTanh::f_cuda(double* x, size_t size) {
try {
thrust::device_ptr<double> ptr(x);
thrust::transform(ptr, ptr + size, ptr, tanh_func());
} catch(thrust::system_error e) {
std::cerr << e.what() << std::endl;
}
}
// .cpp file which contains C++0x code if it matters
ActivationFunction::f_cuda(m_outputs_cuda, m_outputs_size_cuda);
m_outputs_cuda was allocated with cudaMallocPitch and with size m_outputs_size_cuda * sizeof(double)
