Public Member Functions | |
| void | init (size_t size, bool onGpu=false) |
 Public Member Functions inherited from ManagedMemory< int > | |
| int * | data () |
| Return a pointer to the actual data Return a CPU pointer to the actual data, will move data from GPU to CPU if necessary In GPU mode, care must be taken when calling this from multiple cpu threads Only the "GPU Owner" thread may call this when the data is actually on the GPU. Ideally call once from main thread to get data onto the cpu before launching other cpu threads. | |
| const int * | data () const |
| Return a const pointer to the actual data Return a CPU pointer to the actual data, will move data from GPU to CPU if necessary In GPU mode, care must be taken when calling this from multiple cpu threads Only the "GPU Owner" thread may call this when the data is actually on the GPU. Ideally call once from main thread to get data onto the cpu before launching other cpu threads. | |
| int * | dataGpu () |
| Get a GPU data pointer (must be called from GPU owner thread) | |
| const int * | dataGpu () const |
