Embodiment
In conjunction with following specific embodiments and the drawings, the present invention is described in further detail.Implement process of the present invention, condition, test method etc., except the following content mentioned specially, be universal knowledege and the common practise of this area, the present invention is not particularly limited content.
The present invention proposes a kind of MPSoC task scheduling analytical model method based on UPPAAL-SMC under process variation, see Fig. 1, the frame diagram of Task matching and scheduling Policy evaluation in the present invention.
Framework of the present invention receives configuration setting as input, and a Task matching and scheduling example determined, these parameters are applied in model, and repeatedly run query statement, the final stability of this Task matching and scheduling example under the environment of input parameter that generates shows (i.e. performance output).Wherein, framework reception configuration setting comprises:
1) several task DAG (Directed Acyclic Graph, directed acyclic graph): if DAG is more than 1, then multiple DAG must be mapped on a Task matching and scheduling example when dispatching, and namely all task DAG perform in same scheduling;
2) correlation parameter of MPSoC: comprise the number of processing unit (PE), type, rated disspation and process variation interval, these parameters are relevant to MPSoC.Wherein, process variation interval is the function of a normal distribution, and framework can operationally automatic therefrom selective value, and this value is as the number percent of MPSoC relative to rated power, and user should specify its variance;
3) design constraint: comprise the deadline of all tasks, the maximum power dissipation of MPSoC, and the performance output etc. needing realization.
Statistical model checks that (Statistical Model Checking, SMC) technology produces a large amount of test findings by the random walk of model, and sets up statistical conclusions for specific inquiry constraint.
Based on the MPSoC task scheduling analytical model method of UPPAAL-SMC under the process variation that the present invention proposes, for given scheduling strategy, first with the example of this strategy generating task scheduling, then this instance transfer is become the input parameter of framework; Framework accepts these input parameters, can be converted into the configuration file in UPPAAL-SMC model, and run in a model; Again by given constraint inquiry, the performance output of this scheduling strategy under given design constraint just can be drawn.
As shown in Figure 2, the MPSoC task scheduling analytical model method based on UPPAAL-SMC of the present invention comprises: step one: Task matching and scheduling example generation step; Step 2: model conversion step; Step 3: query generation step; Step 4: the analysis of Task matching and scheduling example and appraisal procedure.
Wherein, Task matching and scheduling example generation step is the primary operations assessed scheduling strategy, and this step, according to the scheduling strategy adopted, on specific MPSoC, is given task-set generation Task matching and scheduling example.
After Task matching and scheduling example generates, after being given task-set generation Task matching and scheduling example, execution model switch process, this step carries out task modeling, PE modeling and power consumption modeling under the prerequisite considering process variation, form task model, PE model and power consumption model, and carry out the backstage configuration of model, Task matching and scheduling example is carried out model conversion.
Framework of the present invention is made up of two parts: foreground model and backstage configuration.Foreground model includes the modeling to task, PE and power consumption; Backstage configuration includes the configuration setup parameter that framework receives, and the description to Task matching and scheduling application background.Backstage configuration controls the information of all structural, logicalities, when UPPAAL-SMC carries out initialization to framework, first configuration section can be read, and configuration is applied in Task matching and scheduling example, perform constraint inquiry again, information in the configuration of backstage and task-set, PE closely bound up, decide the operational process of framework.
As shown in Figure 3, framework of the present invention does not carry out modeling to whole task sequence, but carries out abstract in unification to all task nodes, carries out modeling to single task role node, and according to the configuring condition of forerunner, descendant node.
Task brings into operation from " initially " node, and runs initialization function (initialize () function), jumps to " preparation " node.In initialize function, first node can read backstage configuration, and judges the forerunner of oneself, the number of descendant node and sequence number; Then, node judges oneself to be the start node of whole task sequence, if so, then generates the random number of Normal Distribution according to backstage configuration, carries out initialization to the process variation of time and power consumption.Framework of the present invention, according to Box-Muller algorithm, utilizes the random function provided in UPPAAL-SMC, and the random number that is evenly distributed generated is converted to normal distribution random number.
After arriving " preparation " node, the predecessor node of task to self judges.If there is no predecessor node (pre_num==0), then jump to " beginning " node; Otherwise, jump to " reception " node, wait for that its predecessor node completes and sends message; When start_task message is come then, first model is selected message, determines whether task communication type message_task_t; , then call is_this function and judge whether it is the message that oneself predecessor node sends if so; If so, then the predecessor node number that oneself is waited for is subtracted one, jump to " beginning " state; Then, its residue predecessor node is judged, has determined that the message to be subjected such as continuation or preparation bring into operation.
After arriving " beginning " node, if task does not have predecessor node, then read from backstage configuration assigned and judge which PE is this task should be assigned on, then assignment messages (assign_proc) is sent to target P E, this task of notification target PE will perform, and jump to " RUN " state.
After arriving " RUN " node, task enters waiting status.Now, wait executor PE finishes the work by this task, and sends finish_task (task completes) signal; The flowing of task execution time is responsible for by PE.When finish_task message arrives, model judges whether it is message_task_t, then judges that whether oneself is the recipient of message, if so, then jumps to " completing " node.
After arriving " completing " node, task can judge whether oneself exists descendant node, if not, can jump to " termination " node, terminate the operation of self; If this task exists descendant node, then can jump to " transmission " node, and enter a circulation; When the residue descendant node of task is greater than 0, task can send start_task (task starts) message in each circulation, notifies that its descendant node can bring into operation, and upgrades the descendant node counter of oneself.
As shown in Figure 4, in the present invention, PE model is the abstract model to all PE, is configured the performance of control PE, comprise power consumption, process variation etc. by backstage.The start node of PE model is " beginning ", when being in " beginning " node, Processor (processor) first calls queue_empty function and judges queue, if queue is empty, namely this Processor current does not receive any task requests, then enter " wait " node of below; If queue is not empty, then jump to " RUN " node, and the head task read in queue, sid (secure identifier), tid (Thread control symbol), real_time_cost (actual execution time) etc. are upgraded, sid and tid is made to record the information of the current task that will perform, real_time_cost preserves the actual finish time calculated according to process variation, executes the task prepare for " RUN " node.Meanwhile, PE model sends a request_power signal, informs that power consumption model upgrades power consumption situation; In addition, as shown in the figure, " beginning " node contains the directed edge of a self-loopa, the state transition on this limit triggers when receiving assign_proc signal, first message is selected, determine whether the signal of message_proc_t type, then judge oneself to be whether the recipient of this message, if so, then the task queue of oneself is added.All there is embodiment on similar self-loopa limit at " wait ", " RUN ", " completing " node.At " beginning " node, Processor judges whether queue is empty, and carries out corresponding actions, monitors assign_proc signal simultaneously.
When Processor arrives " RUN " node, can stop regular time at this node, this point is realized by the combination of invariant and redirect condition.And while state transition, Processor sends a finish_task signal, carry sid and tid of goal task, inform that inter-related task model running terminates, make goal task from " RUN " node migrates to " completing " node, meanwhile, " RUN " node also performs out team's operation to task queue when moving, and have updated task queue.From semanteme, " RUN " node is responsible for the operation of queue head task, according to time rating and process variation determination actual execution time, and sends message after the time terminates, notice task.In addition, also there is the assign_proc message that a loop is sent to monitor task model in " RUN " node.
" complete " node to exist as an intermediate node, because UPPAAL-SMC forbids the synchronization value that setting two is different on same state transition limit, therefore Processor is allowed first to arrive " completing " node, again from " completing " node migrates to " " node, complete the tasks carrying process that it is once complete.From " completing " node migrates to " " in the process of node, Processor sends a free_power signal, the power consumption that notice power consumption model release Processor takies, and upgrades the information of power consumption.
PE model is by communicating between task model with power consumption model, and the implementation of control task, with the renewal of power consumption information, is the model that in whole framework, dynamic is stronger.Include the loop of multiple monitoring new task message in a model, add some phraseological redundancies, but efficiently avoid the situation that PE model does not receive new task message, achieve functionally complete and semantically perfect.
As shown in Figure 5, power consumption model is responsible for carrying out monitoring to the situation of power consumption and safeguarding, comprises " process " and " wait " two nodes.State that power consumption model is initially in " process ", and when " process " and " wait " state, all receive two kinds of signals, respectively: request_power (power demands) and free_power.When power consumption model receives the signal of request_power, it can according to the pid of sender, call power_alloc function, increase current power consumption current_power, and, if current power consumption is greater than history maximum power dissipation (current_power >=max_power), then upgrade max_power; When power consumption model receives the signal of free_power, according to the pid of sender, call power_free function, reduce current power consumption.
When power consumption model is in " process " state, when not receiving signal, jump to " wait " state; When power consumption model be in " wait " state receive signal time, jump to " process " state.Power consumption model switches between two states, and completes the monitoring to power loss signal in the process switched.During checking, only need to compare max_power and design constraint, just can realize the judgement to power constraints.
The present invention propose based in the MPSoC task scheduling analytical model method of UPPAAL-SMC, when for specific MPSoC design constraint and resource situation, after creating task scheduling according to specific dispatching algorithm, need be converted into the backstage configuration of model according to selected ListScheduling (list scheduling) and BULB (branch's cutting) algorithm, thus control foreground model produces different behaviors.
Framework of the present invention contains a model backstage equipped with switches, as long as the result that dispatching algorithm generates comprises this three partial information of id of task id, start time, PE, framework can be converted into and can be configured by the backstage of Model Identification.
In a model, all task sequencings are all represented by dependence, according to concrete task scheduling, for original Task Dependent relation adds new dependence.By crossover tool, the precedence relationship between task can be decided, and use in the backstage configuration of the instrument write UPPAAL-SMC in framework; The specified execution time of task and the power consumption attribute of PE, can write direct in overall array; Other transfer process and said process similar, repeat no more.
After model conversion step completes, perform query generation step, realize constraint inquiry by stochastic model, and generate statistics by UPPAAL-SMC.When the different Task matching and scheduling example of use generates priced timed automata network (Network of Priced Timed Automata, NPTA) during model, need to compare different task and distribute the performance output with Scheduling instances, generate many different inquiries according to design constraint and verify for UPPAAL-SMC.In UPPAAL-SMC, have employed the inquiry of following form:
Pr[<=x](<>Task(0).Finish&&max_power<=y);
Wherein, Task (0) .Finish represents completing of whole task directed acyclic graph (Directed Acyclic Graph, DAG); Max_power<=y represents that maximum power dissipation can not more than y.
In UPPAAL-SMC, constraint inquiry has been come by repeatedly stochastic simulation; After having simulated each time, UPPAAL-SMC can verify whether present confinement is met, and provides statistics.After all stochastic models complete, UPPAAL-SMC can generate statistics automatically, according to these statisticss, can judge the quality of scheduling strategy.
After in constraint, inquiry completes, UPPAAL-SMC generates this statistical information run, and provides the result of operation in the mode of chart or data.By changing the content of inquiry, UPPAAL-SMC repeatedly can be run to understand under different demands, the performance situation of each Task matching and scheduling example.
The inventive method can under same MPSoC environment, and the different instances of different Task matching and scheduling strategy generating carries out across comparison, is convenient to the Task matching and scheduling strategy selecting when determining chip design to be applicable to; Similarly, also can adopt different MPSoC frameworks, run on different Task matching and scheduling strategies respectively on a different architecture, and by the contrast to Task matching and scheduling example, determine to show more excellent MPSoC framework.By the assessment of these two aspects being combined with comparing, the devisers of MPSoC can carry out decision-making, select at task matching and between scheduling strategy and the framework of MPSoC, to obtain best combination.
The MPSoC task scheduling analytical model method based on UPPAAL-SMC that the present invention proposes, according to relevant information and the scheduling strategy of given MPSoC, the different TAS that the present invention can generate according to scheduling strategy effectively contrast scheduling strategy, also can be used for comparing different TAS examples.The scheduling strategy that can produce optimum solution in process variation situation is not being considered in intuition assessment, is considering may not to be exactly optimum selection in process variation situation; And for the deviser of MPSoC, the present invention when considering selection scheduling strategy in process variation situation, can adopt specific strategy for different MPSoC, experimentally data and actual conditions select the combination of optimum, make performance yield maximization.
Protection content of the present invention is not limited to above embodiment.Under the spirit and scope not deviating from inventive concept, the change that those skilled in the art can expect and advantage are all included in the present invention, and are protection domain with appending claims.
