The present invention relates to the field of computer technologies, and in particular, to a method and an apparatus for configuring an interactive numerical simulation device, and an electronic device.

Background

At present, the atmospheric numerical simulation is widely used, wherein the atmospheric numerical simulation refers to the simulation of the movement and change of the atmosphere through a mathematical model and a computer so as to predict weather, air quality, climate change and the like in a certain period of time; because the numerical model software for executing the numerical model needs to solve a complex atmospheric diffusion and pollution chemical reaction equation set, the operation calculation amount of the numerical model software is larger; therefore, in order to shorten the simulation calculation time to meet the timeliness requirement of business application, most of weather/air quality numerical model software is MPI (Massage Passing Interface, information transfer interface) parallel programs, and multiple calculation nodes (i.e. devices) and multiple processes are supported to run in parallel, so that the overall running time is reduced. Correspondingly, when a plurality of devices are adopted for numerical simulation, the number of the required devices is determined; however, in the prior art, the equipment quantity configuration is generally determined for a model system (i.e., model software) with specific simulation area and spatial resolution after a plurality of groups of test experiments are performed in the early stage of system construction, so that the system construction is performed according to the determined equipment quantity configuration, and the system construction does not need to be adjusted and changed again; for model configuration of different simulation areas and spatial resolutions, corresponding multiple groups of tests need to be carried out again, so that when the simulation areas or the spatial resolutions are changed, a target device configuration scheme (i.e. the number of the adapted devices) is difficult to determine quickly, and a large amount of test resources are consumed. Based on this, how to conveniently determine the target device configuration scheme, so as to improve the estimation efficiency and reduce the test resource consumption becomes a research hotspot.

S102, determining a grid division result of each layer of target nested region based on the target region indication information and the spatial resolution of each layer of target nested region.

Specifically, for any target nesting region in the M-layer target nesting region, the electronic device may determine a region size (i.e., a region size) of the target simulation region based on the target region indication information, where one region size includes a region lateral length and a region longitudinal length of the corresponding simulation region; in this case, the electronic device may determine the meshing result of any one of the target nested regions based on the region lateral length and the region longitudinal length of the target simulation region, and the spatial resolution of any one of the target nested regions. It should be understood that, when the number of the target simulation areas is plural, the electronic device may determine the area size of the corresponding target simulation area (i.e., the area size of any target nesting area) based on the target area indication information of the target simulation area corresponding to any target nesting area, where one area size may also refer to the area lateral length and the area longitudinal length of the corresponding nesting area; in this case, the electronic device may determine the meshing result of any target nesting region based on the region lateral length and the region longitudinal length of the target simulation region corresponding to any target nesting region (i.e., the region lateral length and the region longitudinal length of any target nesting region), and the spatial resolution of any target nesting region. For ease of illustration, the following description will take a target simulation area as an example.

Optionally, the electronic device may further determine central point position information of any target nesting area based on the target area indication information, and start to spread outwards from the central point indicated by the central point position information according to the spatial resolution of any target nesting area until grid division of any target nesting area is completed, so as to obtain a grid division result of any target nesting area.

Wherein one meshing result may be used to indicate the number of horizontal meshes (i.e., nx×ny) and the number of vertical layers (NZ) of the corresponding nesting region; wherein, a horizontal grid number can be determined based on a horizontal grid Number (NX) and a vertical grid Number (NY), i.e. a horizontal grid number can be used for indicating the horizontal grid number and the vertical grid number of the corresponding nested region, that is, a grid division result can comprise the horizontal grid number, the vertical grid number and the vertical layer number of the corresponding nested region; specifically, the number of transverse grids of any target nesting region may be a division result between the region transverse length of the target simulation region and the spatial resolution of any target nesting region, and the number of longitudinal grids of any target nesting region may be a division result between the region longitudinal length of the target simulation region and the spatial resolution of any target nesting region.

Optionally, the number of vertical layers in a mesh division result may be a preset number of vertical layers, and the preset number of vertical layers may be empirically set, or may be set according to actual requirements, which is not limited in the present invention; in this case, the vertical number of layers per layer of nested region is the same; alternatively, the vertical layer number of each layer of the target nesting region may be set by the target object through the data setting operation, that is, the target simulation setting data may further include the vertical layer number of each layer of the target nesting region, so that the meshing result of any target nesting region may be determined based on the target region indication information, the spatial resolution of any target nesting region, and the vertical layer number, and so on.

In the embodiment of the invention, one device configuration scheme corresponds to one device number, that is, one device configuration scheme is used for indicating one device number, and the device numbers indicated by the device configuration schemes can be different. Illustratively, the plurality of device configuration schemes may include, but are not limited to: a device configuration scheme for indicating a device number of 1, a device configuration scheme for indicating a device number of 2, a device configuration scheme for indicating a device number of 3, … …, a device configuration scheme for indicating a device number of Q, and the like; the invention is not limited in this regard.

Alternatively, the unit calculation amount time may refer to calculation time required for the unit calculation amount, the unit calculation amount may refer to calculation amount of a single grid and a single time integration step (i.e., a single integration process), that is, the unit calculation amount may refer to calculation amount of one grid in one iteration process; alternatively, the unit communication quantity time consumption may refer to a communication time consumption required for the unit communication quantity, the unit communication quantity may refer to a communication quantity of a single grid overlapping surface and a single time integration step, that is, the unit communication quantity may refer to a communication quantity of one grid overlapping surface in an iterative process, and one grid overlapping surface may be an intersection surface of two grids.

The target simulation scenario refers to a simulation scenario in which the simulation setting data is the target simulation setting data, the simulation scenario referred to herein may also be referred to as a pollution emission control scenario, and the target simulation scenario may also be referred to as a custom simulation scenario. In the embodiment of the present invention, the number of devices adapted to the target simulation scenario when the target simulation scenario performs numerical simulation through the target numerical model may also be referred to as the number of devices adapted to the target simulation scenario, that is, the number of devices adapted to perform numerical simulation on the target simulation scenario through the target numerical model.

In one embodiment, if at least one device configuration scheme with an operation duration smaller than or equal to the expected calculation duration exists in the plurality of device configuration schemes, the operation duration under the target device configuration scheme is smaller than or equal to the expected calculation duration, and the operation duration under the critical device configuration scheme is greater than the expected calculation duration; the critical device configuration scheme refers to any device configuration scheme with the number of devices smaller than that of devices indicated by the target device configuration scheme, or may refer to a device configuration scheme with the largest indicated number of devices in a screening device configuration scheme set, where the screening device configuration scheme set may include all device configuration schemes with operation duration longer than expected calculation duration in multiple device configuration schemes.

Optionally, the electronic device may first select the at least one device configuration scheme from the plurality of device configuration schemes, then select a device configuration scheme with the smallest number of devices from the at least one device configuration scheme, and use the selected device configuration scheme as the target device configuration scheme, that is, the number of devices indicated by the target device configuration scheme is the smallest value among the number of devices indicated by each device configuration scheme in the at least one device configuration scheme.

In another embodiment, if at least one device configuration scheme with the operation duration smaller than or equal to the expected calculation duration does not exist in the multiple device configuration schemes, that is, the operation duration under each device configuration scheme is greater than the expected calculation duration, in this case, the electronic device may use the device configuration scheme with the smallest operation duration in the multiple device configuration schemes as the target device configuration scheme, that is, the operation duration under the target device configuration scheme is smaller than the operation duration under any device configuration scheme except the target device configuration scheme in the multiple device configuration schemes.

In yet another embodiment, the electronic device may sequentially traverse each device configuration scheme of the plurality of device configuration schemes in order of from the small number of devices to the large number of devices, and take the currently traversed device configuration scheme as the current device configuration scheme, in which case, if the operation duration under the current device configuration scheme is less than or equal to the expected calculation duration, the electronic device may take the current device configuration scheme as the target device configuration scheme and complete the traversal (i.e. stop the traversal); if the current device configuration scheme is the last device configuration scheme (i.e. the number of devices indicated by the current device configuration scheme is the maximum value of the number of devices indicated by each device configuration scheme) to be traversed in the multiple device configuration schemes, the current device configuration scheme is taken as the target device configuration scheme, and the traversing is completed. It should be understood that the number of devices indicated by the device configuration scheme in the last traversal process is less than the number of devices indicated by the current device configuration scheme, and the electronic device may complete the traversal after selecting the target device configuration scheme.

Based on the above description, the embodiment of the invention also provides a more specific device configuration method for interactive numerical simulation. Accordingly, the device configuration method of the interactive numerical simulation may be performed by the above-mentioned electronic device (terminal or server); alternatively, the device configuration method of the interactive numerical simulation may be performed by the terminal and the server together. For convenience of explanation, the device configuration method for executing the interactive numerical simulation by the electronic device will be described below; referring to fig. 3, the device configuration method of the interactive numerical simulation may include the following steps S301 to S309:

s301, acquiring target simulation setting data, wherein the target simulation setting data comprises target region indication information of a target simulation region, spatial resolution of each layer of target nesting region in M layers of target nesting regions and expected calculation time length, and M is a positive integer.

S302, determining a grid division result of each layer of target nested region based on the target region indication information and the spatial resolution of each layer of target nested region.

S303, determining the iteration times of each layer of target nested region under the target numerical model, and respectively calculating the target calculation number and the target communication number based on the grid division result of each layer of target nested region and the iteration times of each layer of target nested region under the target numerical model.

In one embodiment, the target simulation setup data may further include a simulation duration for each layer of target nesting area; based on the above, when determining the iteration times of each layer of target nested region under the target numerical model, the electronic device may determine a reference time integral step length and a reference spatial resolution corresponding to the target numerical model, and calculate a time integral step length of each layer of target nested region under the target numerical model based on the reference time integral step length, the reference spatial resolution and the spatial resolution of each layer of target nested region; specifically, for the mth layer target nesting area in the M layer target nesting area, the electronic device may calculate a time integration step length of the mth layer target nesting area under the target numerical model by using formula 1.1, M e [1, M ]:

dtm_d=dt× DXm _d/DX 1.1

Wherein, dtm_d is the time integration step length of the m-th layer target nested region under the target numerical model, DT is the reference time integration step length, DX is the reference spatial resolution, DXm _d is the spatial resolution of the m-th layer target nested region. Illustratively, dt1_d may represent a time integration step of the layer 1 target nesting region under the target numerical model, and dx1_d may represent a spatial resolution of the layer 1 target nesting region.

Further, the iteration times of each layer of target nested region under the target numerical model can be determined based on the time integral step length of each layer of target nested region under the target numerical model and the simulation time length of each layer of target nested region. Specifically, for the mth layer target nesting area in the M layer target nesting areas, the electronic device may calculate the iteration number of the mth layer target nesting area under the target numerical model by adopting formula 1.2:

num_t_m= FTm _d×3600/dtm_d 1.2

Wherein num_t_m is the iteration number of the mth layer target nesting region under the target numerical model, FTm _d is the simulation duration of the mth layer target nesting region, wherein the unit of the time integration step length can be seconds, and the formula 1.2 is illustrated by taking the unit of the simulation duration of the mth layer target nesting region as an example; alternatively, when the unit of the analog time length of the m-th layer target nest area is seconds, equation 1.2 may not be multiplied by 3600 to convert the unit of the analog time length from hours to seconds.

In the embodiment of the present invention, the reference time integration step length and the reference spatial resolution may be determined based on reference analog setting data, where the reference analog setting data includes the spatial resolution of each layer of reference nesting area in N layers of reference nesting areas, and N is a positive integer; based on the above, when determining the reference time integration step length and the reference spatial resolution corresponding to the target numerical model, the electronic device may select a layer of reference nesting region from the N layers of reference nesting regions, and use the spatial resolution of the selected reference nesting region as the reference spatial resolution corresponding to the target numerical model; then, the time integral step length of the selected reference nested region under the target numerical model can be determined, and the time integral step length of the selected reference nested region under the target numerical model is used as the reference time integral step length corresponding to the target numerical model. Optionally, the time integral step length of any reference nested region under the target numerical model may be a multiplication result between a step length coefficient corresponding to the target numerical model and the spatial resolution of any reference nested region, or may be a preset time integral step length corresponding to the target numerical model; the invention is not limited in this regard; alternatively, the step size coefficient or the preset time integration step size corresponding to a numerical model may be set empirically, or may be set according to actual requirements, which is not limited in the present invention.

For example, taking WRF, NAQPMS, CMAQ, CAMx and WRFCHEM as target numerical models, respectively, assume WRF, CMAQ, CAMx and WRFCHEM have step coefficients of 6, 540/27, 600/27 and 6, respectively, and assume that the predetermined time integration step corresponding to NAQPMS is 300; in this case, when the target numerical model is WRF, the reference time integration step dt=6×dx; dt=300 (independent of DX) when the target numerical model is NAQPMS; when the target numerical model is CMAQ, dt=540×dx/27; when the target numerical model is CAMx, dt=600×dx/27; when the target numerical model is WRFCHEM, dt=6×dx, and so on.

In another embodiment, the target simulation setting data may also include an iteration number of each layer of the target nested region under the target numerical model, based on which, when determining the iteration number of each layer of the target nested region under the target numerical model, the electronic device may determine the iteration number of each layer of the target nested region under the target numerical model from the target simulation setting data.

Alternatively, NZ may be used to represent the number of vertical layers in each layer of the reference nesting area when the number of vertical layers in each layer of the reference nesting area is the same. It should be understood that equation 1.3 is illustrated by taking the unit of analog time length as an example of hours, and the invention is not limited thereto; for example, equation 1.3 may not be multiplied by 3600 when the unit of analog time length is seconds. The nxn× NYn × NZn × FTn ×3600/DTn may refer to a total amount of area calculation under an nth layer of reference nesting area, that is, the electronic device may perform a summation operation on the total amount of area calculation under each layer of reference nesting area in the N layer of reference nesting area to obtain a reference calculation amount, and perform a division operation on the reference calculation time consumption and the reference calculation amount of the q-th device configuration scheme to obtain a unit calculation amount time consumption of the q-th device configuration scheme (that is, a unit calculation amount time consumption under the q-th device configuration scheme).

untq= NTq/Σ ((nxn× NYn +nxn× NZn + NYn × NZn) × FTn ×3600/DTn) formula 1.4

Where UNTq is the unit communication quantity time consuming of the q-th device configuration scheme, and NTq is the reference communication time consuming of the q-th device configuration scheme. It should be understood that equation 1.4 is illustrated by way of example in terms of hours of analog time duration, and the invention is not limited in this regard; for example, equation 1.4 may not be multiplied by 3600 when the unit of analog time length is seconds.
