dev_result v vecptr 0 a v vecptr 1 b v dim 0 3 v dim 1 4 cudaMalloc void dev_v sizeof vecarray cudaMemcpy dev_v v sizeof vecarray.. cudaMemcpyHostToDevice copy class object for int i 0 i N i cudaMalloc void dev_v vecptr i v dim i sizeof int for int i 0 i N i copy.. when running. I've checked the problem lies in the two cudaMalloc and cudaMemcpy opertation in the for loop. So my question is..

cudaMemcpy segmentation fault

to go UPDATE It seems now I have solved this problem by cudaMalloc another float pointer A on device and cudaMemcpy the value of.. host. So the segment of code written above becomes float A cudaMalloc void A sizeof float ... ... cudaMemcpy A Grid_dev cdata i sizeof.. Also I don't know the the underlying mechanism of how cudaMalloc and cudaMemcpy work but I think by cudaMalloc a pointer say..

Why does valgrind say basic SDL program is leaking memory?
