= Few Basic CUDA Operations = | |||
== CUDA Memory Allocation | |||
* cudaMalloc((void**)&array, size) | |||
** Allocates object in the device memory. Requires address of a pointer of allocated array and size. | |||
* cudaFree(array) | |||
** Deallocates object from the memory. Requires just a pointer to the array. | |||
== CUDA Data Transfers == | |||
* cudaMemcpy(array_dest, array_orig, size, direction) | |||
** Copy the data from either device to host or host to device . Requires pointers to the arrays, size and the direction type (cudaMemcpyHostToDevice, cudaMemcpyDeviceToHost, cudaMemcpyDeviceToDevice, etc) | |||
