## Data Structure Documentation

## _starpu_mic_async_event

struct _starpu_mic_async_event

MIC needs memory_node to know which MIC is concerned. mark is used to wait asynchronous request. signal is used to test asynchronous request.

Data Fields
unsigned | memory_node |
int | mark |
uint64_t * | signal |

## _starpu_disk_backend_event

struct _starpu_disk_backend_event

Data Fields
void * | backend_event |

struct _starpu_disk_async_event

Data Fields
unsigned | memory_node |
struct _starpu_disk_backend_event_list * | requests |
void * | ptr |
unsigned | node |
size_t | size |
starpu_data_handle_t | handle |

## _starpu_async_channel_event

union _starpu_async_channel_event

this is a structure that can be queried to see whether an asynchronous transfer has terminated or not
