The above process is illustrated below according to an optional embodiment citing:
Above-mentioned steps can recycle to execute the performance evaluation of axial direction part each time using for, and the cycle each time of for is just
To calculate an axial direction part, the above process is the dynamic dispatching to axial direction part, dynamic dispatching refer to dynamically by each for repeatedly
In generation, is assigned on each thread, and each iteration, which represents, calculates an axial direction part, for example, 10 for cycles represent and calculate 10
Axial direction part;The predetermined number of the axial direction part of above-mentioned predetermined number indicated using size in the present embodiment, the size of each size
Also representative for cycle assignments will give each process (thread), the predetermined number (size) of the axial direction part of each predetermined number several times
At least one, size parameters can be used, size parameters, in the case of not using size parameters, size values can not also be used
It is defaulted as 1, each size can be used as a subtask, above-mentioned steps that dynamically subtask is assigned on each thread, point
Timing can distribute to each thread based on prerequisite variable mode.It, can also be according to each when distributing subtask to thread
The performance of thread reallocates 1 iteration to the thread that iteration task is completed every time, if having used size every time according to
So size iterations (axial direction part) of distribution.Judge the execution speed of per thread, the thread distribution completed to very fast iteration
Iteration more times is executed, the distribution of slower thread executes less iteration, and the iterations of per thread processing are that dynamic adjusts
, without quantitative range, it is adjusted at any time according to the disposition of thread, it is uneven to solve each cross-thread load distribution with this
The problem of weighing apparatus.
The mode of above-mentioned this distribution axial direction part is a kind of mode of dynamic dispatching, it is ensured that the load in each process
Equilibrium, to keep the processing time of each process similar, and total processing time is reduced, and ensure that the entire single core combustion of analysis
The analyzing processing speed of charge bar is greatly improved than the prior art, and load balancing refers to that approximately equivalent quantity is distributed between each thread
Work way, to make all threads all keep busy in institute's having time, make task free time minimize, to improve
Treatment effeciency.If load imbalance can cause all threads that will be synchronized at obstacle, most slow task will determine global
Time overhead.
According to the information of the analyze speed of each process remaining axial direction part of sub-distribution again, in an optional embodiment
In, first, it is determined that the speed speed of each process analysis axial direction part;Secondly, priority row is carried out to process according to speed speed
Sequence;Finally, remaining axial direction part is distributed according to priority height.
The above process is illustrated below according to an optional embodiment citing:
When analyzing single rod, since the solution procedure between axial direction part is mutually without influence, so can carry out parallel.
To being realized parallel by openMP sentences for axial direction part.Inside each single rod program, the analysis of axial direction part can be
Pass through for (i=0;i<M;I++) cycle is realized, meanwhile, multiple threads are opened by openMP sentences, axial direction part is carried out simultaneously
Row processing, for example, one shares 10 cycles, 10 cycle calculations is split and go to execute to different processes, each time cycle meter
Calculate represent calculate an axial direction part, by the analysis of entire single rod be converted into the temperature to each axial direction part, ess-strain, internal pressure,
The performances such as involucrum corrosion carry out numerical solution;Be arranged size=2, represent divided in each subtask execution recycle twice,
Two axial direction parts are namely calculated, are subtask respectively:01,23,45,67,89;10 are recycled, is divided into 3 processes
There are many division results, may be as shown in figure 5, No. 0 process executes the 0th, 1,6,7 cycle.For another example, it one 10 is shared follows
Ring is divided into 3 processes, and as size=1, subtask is respectively:0,1,2,3,4,5,6,7,8,9;10 are recycled, is divided
It, may be as shown in fig. 6, No. 1 process executes the 1st, 4 cycle to there are many division results in 3 processes.
The performance of above-mentioned axial direction part is weighed by many indexes, in an optional embodiment, axis
Can be temperature, ess-strain, internal pressure, involucrum corrosion etc. to the performance of section.
Said program is the parallel processing to each axial direction part in single rod, can also be carried out between each single rod parallel
Processing, in an optional embodiment, a kind of multiple nuclear fuel rod method for analyzing performance, including:First, multiple cores are obtained
The information of fuel rod;Secondly, the information of multiple nuclear fuel rods is distributed to multiple processes, wherein each of multiple processes into
Journey corresponds to the information of a nuclear fuel rod, and the quantity of process is identical as the quantity of nuclear fuel rod;Then, according to the letter of nuclear fuel rod
Cease the performance for analyzing multiple nuclear fuel rods simultaneously in multiple processes.
The information of above-mentioned fuel rod be can weigh the input information of some Most spent fuel rod, that is, with temperature, stress
The corresponding input informations such as strain, internal pressure, involucrum corrosion.For example, distribution of the temperature on pellet and involucrum is the core of input
The information of fuel rod, the corresponding temperature exported represent the performance of nuclear fuel rod.The input information for influencing temperature performance is also wrapped
Include the parameters such as the ring diameter of axial direction part, involucrum internal-and external diameter, gap heat transfer coefficient, pellet thermal conductivity.The corresponding fuel rod of ess-strain
Information refer to the parameters such as elasticity modulus, modulus of shearing, Poisson's ratio;The information of the corresponding fuel rod of internal pressure refers to temperature, transmitting
The parameters such as rate;The information that involucrum corrodes corresponding fuel rod refers to the parameters such as fusing point, phase transformation.
So that multiple single rods is separately sent to different calculate node (processor) through the above steps, can ask simultaneously
The related physical quantity for solving multiple fuel rods improves solution efficiency so as to shorten the solution time.Above-mentioned steps can to more sticks into
Row parallel performance is analyzed, or even carries out performance evaluation to the fuel rod of Whole core, and results of performance analysis is more compared with single rod program
Accurately.When carrying out performance evaluation to more sticks, the influence between ignoring between stick and stick carries out performance evaluation execution to each stick
It is identical operation, the difference is that the primary condition (input data) of each stick is different.It is more using the one way sequence of MPI
The parallel mode of data, as shown in fig. 7, the input data of different fuel stick is published to different processes by No. 0 process, respectively
Process carries out identical processing to input data, and different processes are to different fuel stick into trip temperature, ess-strain, internal pressure, involucrum
The performances such as corrosion carry out numerical solution.
The above method is the parallel mode between single rod and single rod, can also be in conjunction with the parallel mode in single stick, by two
Kind parallel mode is used in combination, and each single rod in the parallel mode between single rod and single rod carries out the division of axial direction part, from
And accelerate the processing speed of each single rod, the parallel method in parallel method and single rod between single rod can be more quickly and accurate
The true performance for detecting multiple fuel rods or even entire fuel assembly stick.
