Activity
Like Server it models an activity that takes a and provides b having state s.
But unlike the former the activity is destined for simulation within Net computation.
Instances
| (Show s, ResultItemable (ResultValue s)) => ResultProvider (Activity s a b) |
Arguments
| :: (a -> Process b) | provide an output by the specified input |
| -> Simulation (Activity () a b) |
Create a new activity that can provide output b by input a.
By default, it is assumed that the activity utilisation cannot be preempted, because the handling of possible task preemption is rather costly operation.
Arguments
| :: (s -> a -> Process (s, b)) | provide a new state and output by the specified old state and input |
| -> s | the initial state |
| -> Simulation (Activity s a b) |
Create a new activity that can provide output b by input a
starting from state s.
By default, it is assumed that the activity utilisation cannot be preempted, because the handling of possible task preemption is rather costly operation.
Arguments
| :: Bool | whether the activity can be preempted |
| -> (a -> Process b) | provide an output by the specified input |
| -> Simulation (Activity () a b) |
Create a new preemptible activity that can provide output b by input a.
newPreemptibleStateActivity Source
Arguments
| :: Bool | whether the activity can be preempted |
| -> (s -> a -> Process (s, b)) | provide a new state and output by the specified old state and input |
| -> s | the initial state |
| -> Simulation (Activity s a b) |
Create a new activity that can provide output b by input a
starting from state s.
Processing
activityNet :: Activity s a b -> Net a b Source
Return a network computation for the specified activity.
The computation updates the internal state of the activity. The usual case is when the computation is applied only once in a chain of data processing. Otherwise; every time the computation is used, the state of the activity changes. Sometimes it can be indeed useful if you want to aggregate the statistics for different activities simultaneously, but it would be more preferable to avoid this.
If you connect different activity computations returned by this function in a chain
with help of >>> or other category combinator then this chain will act as one
whole, where the first activity will take a new task only after the last activity
finishes its current task and requests for the next one from the previous activity
in the chain. This is not always that thing you might need.
Activity Properties
activityInitState :: Activity s a b -> s Source
The initial state of the activity.
activityState :: Activity s a b -> Event s Source
Return the current state of the activity.
See also activityStateChanged and activityStateChanged_.
activityTotalUtilisationTime :: Activity s a b -> Event Double Source
Return the counted total time when the activity was utilised.
The value returned changes discretely and it is usually delayed relative to the current simulation time.
See also activityTotalUtilisationTimeChanged and activityTotalUtilisationTimeChanged_.
activityTotalIdleTime :: Activity s a b -> Event Double Source
Return the counted total time when the activity was idle.
The value returned changes discretely and it is usually delayed relative to the current simulation time.
See also activityTotalIdleTimeChanged and activityTotalIdleTimeChanged_.
activityTotalPreemptionTime :: Activity s a b -> Event Double Source
Return the counted total time when the activity was preemted waiting for the further proceeding.
The value returned changes discretely and it is usually delayed relative to the current simulation time.
See also activityTotalPreemptionTimeChanged and activityTotalPreemptionTimeChanged_.
activityUtilisationTime :: Activity s a b -> Event (SamplingStats Double) Source
Return the statistics for the time when the activity was utilised.
The value returned changes discretely and it is usually delayed relative to the current simulation time.
See also activityUtilisationTimeChanged and activityUtilisationTimeChanged_.
activityIdleTime :: Activity s a b -> Event (SamplingStats Double) Source
Return the statistics for the time when the activity was idle.
The value returned changes discretely and it is usually delayed relative to the current simulation time.
See also activityIdleTimeChanged and activityIdleTimeChanged_.
activityPreemptionTime :: Activity s a b -> Event (SamplingStats Double) Source
Return the statistics for the time when the activity was preempted waiting for the further proceeding.
The value returned changes discretely and it is usually delayed relative to the current simulation time.
See also activityPreemptionTimeChanged and activityPreemptionTimeChanged_.
activityUtilisationFactor :: Activity s a b -> Event Double Source
It returns the factor changing from 0 to 1, which estimates how often the activity was utilised.
This factor is calculated as
totalUtilisationTime / (totalUtilisationTime + totalIdleTime + totalPreemptionTime)
As before in this module, the value returned changes discretely and it is usually delayed relative to the current simulation time.
See also activityUtilisationFactorChanged and activityUtilisationFactorChanged_.
activityIdleFactor :: Activity s a b -> Event Double Source
It returns the factor changing from 0 to 1, which estimates how often the activity was idle.
This factor is calculated as
totalIdleTime / (totalUtilisationTime + totalIdleTime + totalPreemptionTime)
As before in this module, the value returned changes discretely and it is usually delayed relative to the current simulation time.
See also activityIdleFactorChanged and activityIdleFactorChanged_.
activityPreemptionFactor :: Activity s a b -> Event Double Source
It returns the factor changing from 0 to 1, which estimates how often the activity was preempted waiting for the further proceeding.
This factor is calculated as
totalUtilisationTime / (totalUtilisationTime + totalIdleTime + totalPreemptionTime)
As before in this module, the value returned changes discretely and it is usually delayed relative to the current simulation time.
