Wherein, i is cpu busy percentage, and j is LLC miss rate and k is magnetic disc access rate, and valueAvg [i] [j] [k] is dynamic power consumption corresponding to parameter i, j, k in target power consumption parameter sets, and n is the number of described initial power consumption parameter sets, value_p[i] [j] [k] in the initial power consumption parameter sets of at least two, the dynamic power consumption that in the initial power consumption parameter sets of pth, parameter i, j, k are corresponding.

Due under the different boot sequence at least two, obtain the initial power consumption parameter sets of at least two, and using the average of initial for this at least two power consumption parameter sets as target power consumption parameter sets, namely multiple repairing weld has been carried out, and using the average of multiple repairing weld as target sample value, application power consumption parameter set coverage rate is wider so on the whole, have more randomness, more can reflect the true ruuning situation of application, reduce the uncertainty of unitary sampling, improve the accuracy of target power consumption parameter sets.Example, the number of this initial target power consumption parameter set is more than or equal to 3, and less than or equal to 5.

Step 204, according to target power consumption parameter sets, set up three-dimensional LUT.

Example, it is possible to the target power consumption parameter sets according to each application, set up a three-dimensional LUT for each application. When three-dimensional LUT may be used for record object application operation, the often corresponding relation of group variable parameter and dynamic power consumption.

When setting up three-dimensional LUT for an application, can according to the rate of people logging in of the cpu busy percentage of record, the certain rate of LLC and disk in the target power consumption parameter sets obtained, it is determined that the excursion of the excursion of cpu busy percentage, the excursion of LLC miss rate and magnetic disc access rate. Optionally, the excursion of cpu busy percentage can be: [0%, 400%), example, the unit of cpu busy percentage can be 1%, now the excursion of this cpu busy percentage be [0,400); The unit of LLC miss rate can be 2000000 times per second, the excursion of LLC miss rate can be: [0,500), the unit of magnetic disc access rate can be 2000 times per second, the excursion of magnetic disc access rate can be: [0,50).

In determining one group of variable parameter after the excursion of each parameter, it is possible to according to the corresponding relation recorded in the excursion of cpu busy percentage, the excursion of LLC miss rate, the excursion of magnetic disc access rate and target power consumption parameter sets, set up initial LUT. Can being provided with at least one position on this initial LUT, and this each position is corresponding with one group of variable parameter, on the position that in target power consumption parameter sets, arbitrary group of variable parameter is corresponding, record has the dynamic power consumption that arbitrary group of variable parameter is corresponding. Example, as shown in Fig. 2-2, this initial LUT can be a three-dimensional table, and the three of this three-dimensional table the inputs respectively cpu busy percentage of this application, LLC miss rate and magnetic disc access rate, and this three-dimensional table is output as the dynamic power consumption of this application. This three-dimensional table can be made up of at least one two-dimensional table M, and two inputs of each two-dimensional table M can be cpu busy percentage and LLC miss rate, and at least one magnetic disc access rate one_to_one corresponding of this at least one two-dimensional table M and acquisition, each two-dimensional table M is output as the cpu busy percentage in corresponding for this two-dimensional table M magnetic disc access rate, this two-dimensional table M and the dynamic power consumption corresponding to LLC miss rate in this two-dimensional table M.

Two-dimensional table schematic diagram in a kind of initial LUT that Fig. 2-3 provides for the embodiment of the present invention, as Figure 2-3, the transverse direction input of this two-dimensional table can be LLC miss rate, the longitudinal direction input of this two-dimensional table can be cpu busy percentage, and magnetic disc access rate corresponding to this two-dimensional table can be that 2000 times of 2 times are per second. Example, when cpu busy percentage is 7 times 1%, 2000000 times that LLC miss rate is 2 times per second, this magnetic disc access rate can be 2000 times of 2 times per second time, the dynamic power consumption of this application is in this two-dimensional table, and on the position of eighth row the 3rd row, the dynamic power consumption of record can be 16W (watt). When cpu busy percentage is 9 times 1%, 2000000 times that LLC miss rate is 2 times per second, this magnetic disc access rate can be 2000 times of 2 times per second time, the dynamic power consumption of this application is in this two-dimensional table, and on the position of the 10th row the 3rd row, the dynamic power consumption of record can be 28W (watt).

After establishing this initial LUT, it is possible to according to the dynamic power consumption in target power consumption parameter sets, it is determined that room dynamic power consumption is also inserted the position that room variable parameter is corresponding by room dynamic power consumption that room variable parameter is corresponding, obtain three-dimensional LUT.It should be noted that this room variable parameter can be do not record the variable parameter that the position of dynamic power consumption is corresponding on this initial LUT. As Figure 2-3, in this two-dimensional table, the position of the second row secondary series does not record dynamic power consumption, now, it is believed that the covert parameter in this room is cpu busy percentage is the 1% of 1 times, 2000000 times that LLC miss rate is 1 times per second, and 2000 times that this magnetic disc access rate can be 2 times per second.

After establishing this initial LUT, when obtaining three-dimensional LUT according to target power consumption parameter sets and initial LUT, it is possible to the dynamic power consumption according to having been recorded with in this initial LUT determines room dynamic power consumption. Example, two-dimensional table schematic diagram in a kind of three-dimensional LUT that Fig. 2-3 provides for the embodiment of the present invention, as in Figure 2-4, each position of the first row LUT [0] [] in two-dimensional table can be inserted 0, show when room variable parameter is cpu busy percentage be 1% and magnetic disc access rate are 2 times 2000 times of 1 times per second time, the dynamic power consumption of this application is 0W.

In row LUT [CPU] [] in this two-dimensional table:

1) if this row exists continuous print blank sequence (at least 2 positions have not recorded dynamic power consumption continuously), and former and later two neighbor locations of this continuous print blank sequence all have been recorded with dynamic power consumption, then the meansigma methods of the dynamic power consumption of these two neighbor location records is inserted each position in this continuous print blank sequence, or, in this continuous print blank sequence, linearly insert dynamic power consumption according to the dynamic power consumption of these two neighbor location records.

Example, as Figure 2-3, LUT [4] [4] and LUT [4] [5] has not recorded dynamic power consumption, namely the LUT [4] [4] in this two-dimensional table and [5] two positions of LUT [4] are continuous print blank sequence, it is expert in LUT [4] [], two neighbours respectively LUT [4] [3] (=8) before and after this continuous print blank sequence and LUT [4] [6] (=10), and the meansigma methods of LUT [4] [3] (=8) and LUT [4] [6] (=10) is 9, then as in Figure 2-4, 9 can be all inserted in LUT [4] [4] and [5] two positions of LUT [4].

2) if continuous print blank sequence has only neighbor location to have been recorded with dynamic power consumption, then the dynamic power consumption of this unique neighbor location record is inserted each position in this continuous print blank sequence.

Example, as Figure 2-3, LUT [3] [0], LUT [3] [1] and LUT [3] [2] has not recorded dynamic power consumption, i.e. LUT [2] [0] in this two-dimensional table, LUT [2] [1] and [2] three positions of LUT [2] are continuous print blank sequence, it is expert in LUT [2] [], the neighbor location that this continuous print blank sequence record has dynamic power consumption is LUT [2] [3] (=5), then as in Figure 2-4, can in LUT [2] [0], LUT [2] [1] and [2] three positions of LUT [2] all insert 5.

In first row LUT [] [0] in this two-dimensional table:

1) if the farthest position of distance and position LUT [0] [0] has not recorded dynamic power consumption, then the dynamic power consumption of record on position nearest for this farthest position of distance in first row LUT [] [0] can be inserted this farthest position.

Example, as Figure 2-3, LUT [9] [0] is in first row LUT [] [0], the position that distance and position LUT [0] [0] is farthest, LUT has not recorded dynamic power consumption on [9] [0], and the dynamic power consumption of the upper record of this farthest position LUT [8] [0] nearest for position LUT [9] [0] of distance is 28 in first row LUT [] [0], then as in Figure 2-4, it is possible to insert 28 in position LUT [9] [0].

2) if these row exist continuous print blank sequence (at least 2 positions have not recorded dynamic power consumption continuously), and former and later two neighbor locations of this continuous print blank sequence all have been recorded with dynamic power consumption, then in this continuous print blank sequence, linearly insert dynamic power consumption according to the dynamic power consumption of these two neighbor location records.

One group of target variable parameter when step 205, acquisition intended application operation.

After establishing three-dimensional LUT, and when intended application is run on computers, if needing to measure the overall power of this intended application, then can directly obtain one group of target variable parameter when this intended application is run, example, this intended application of each moment has one group of variable parameter, when needing to measure intended application overall power at a time, can obtaining one group of target variable parameter of this certain moment intended application, this group of target variable parameter can include target CPU utilization, target LLC miss rate and target disk rate of people logging in.

Step 206, in three-dimensional LUT, search the target dynamic power consumption of record on one group of position corresponding to target variable parameter.

After the one group of target variable parameter obtaining this intended application, the target CPU utilization in this group of target variable parameter can be searched in the three-dimensional LUT established, position that target LLC miss rate is corresponding with target disk rate of people logging in, and obtain the target dynamic power consumption of record on the position that this target variable parameter is corresponding.

Step 207, determine the overall power of intended application according to target dynamic power consumption.

After determining the dynamic power consumption of this intended application, first, the number of the application run on computer can be obtained, and according to the quiescent dissipation of computer obtained in step 201, the number of application that computer runs and quiescent dissipation computing formula, determining quiescent dissipation when intended application is run, this quiescent dissipation computing formula can be:

P_{App(i)_static}=P_{Host_static}/N_App;

Wherein, P_{App(i)_static}Quiescent dissipation when running for intended application, P_{Host_static}For the quiescent dissipation of computer, N_AppThe number of the application for running on computer.

It is then possible to the target dynamic power consumption of quiescent dissipation when running according to intended application, intended application and overall power computing formula, it is determined that the overall power of intended application, this overall power computing formula can be:

P_App(i)=P_{App(i)_static}+P_{App(i)_dynamic};

Wherein, P_App(i)For the overall power of intended application, P_{App(i)_dynamic}For corresponding dynamic power consumption, P_{App(i)_static}Quiescent dissipation for intended application.

The quiescent dissipation assuming this computer is 150W, and this computer runs 5 application, then can obtain according to quiescent dissipation computing formula, and the quiescent dissipation of each application on this computer is 30W. If the dynamic power consumption of intended application searched in the three-dimensional LUT of intended application is 40W, then can determine that the overall power of this intended application is 70W according to overall power computing formula.
