struct sc_hypervisor_wrapper |
Wrapper of the contexts available in StarPU which contains all information about a context obtained by incrementing the performance counters. it is attached to a sched_ctx storing monitoring information
Data Fields | ||
---|---|---|
unsigned | sched_ctx |
the monitored context |
struct sc_hypervisor_policy_config * | config |
The corresponding resize configuration |
double | start_time_w[STARPU_NMAXWORKERS] |
the start time of the resizing sample of the workers of this context |
double | current_idle_time[STARPU_NMAXWORKERS] |
The idle time counter of each worker of the context |
double | idle_time[STARPU_NMAXWORKERS] |
The time the workers were idle from the last resize |
double | idle_start_time[STARPU_NMAXWORKERS] |
The moment when the workers started being idle |
double | exec_time[STARPU_NMAXWORKERS] |
Time during which the worker executed tasks |
double | exec_start_time[STARPU_NMAXWORKERS] |
Time when the worker started executing a task |
int | worker_to_be_removed[STARPU_NMAXWORKERS] |
List of workers that will leave the context (lazy resizing process) |
int | pushed_tasks[STARPU_NMAXWORKERS] |
Number of tasks pushed on each worker in this context |
int | poped_tasks[STARPU_NMAXWORKERS] |
Number of tasks poped from each worker in this context |
double | total_flops |
The total number of flops to execute by the context |
double | total_elapsed_flops[STARPU_NMAXWORKERS] |
The number of flops executed by each workers of the context |
double | elapsed_flops[STARPU_NMAXWORKERS] |
number of flops executed since last resizing |
size_t | elapsed_data[STARPU_NMAXWORKERS] |
Quantity of data (in bytes) used to execute tasks on each worker in this context |
int | elapsed_tasks[STARPU_NMAXWORKERS] |
Number of tasks executed on each worker in this context |
double | ref_speed[2] |
the average speed of the type of workers when they belonged to this context 0 - cuda 1 - cpu |
double | submitted_flops |
Number of flops submitted to this context |
double | remaining_flops |
Number of flops that still have to be executed by the workers in this context |
double | start_time |
Start time of the resizing sample of this context |
double | real_start_time |
First time a task was pushed to this context |
double | hyp_react_start_time |
Start time for sample in which the hypervisor is not allowed to react bc too expensive |
struct sc_hypervisor_resize_ack | resize_ack |
Structure confirming the last resize finished and a new one can be done. Workers do not leave the current context until the receiver context does not ack the receive of these workers |
starpu_pthread_mutex_t | mutex |
Mutex needed to synchronize the acknowledgment of the workers into the receiver context |
unsigned | total_flops_available |
Boolean indicating if the hypervisor can use the flops corresponding to the entire execution of the context |
unsigned | to_be_sized |
boolean indicating that a context is being sized |
unsigned | compute_idle[STARPU_NMAXWORKERS] |
Boolean indicating if we add the idle of this worker to the idle of the context |
unsigned | compute_partial_idle[STARPU_NMAXWORKERS] |
Boolean indicating if we add the entiere idle of this worker to the idle of the context or just half |
unsigned | consider_max |
consider the max in the lp |
