[0002] With the development of science and technology, people can now build simulation systems to simulate actual work. After that, they only need to modify the parameters in the simulation system.

The illustrative embodiments and descriptions of this specification are used to explain this specification and do not constitute an improper limitation on this specification. In the drawings:

[0068] In order to make the purpose, technical solutions and advantages of this specification more clear, the technical solutions of this specification will be clearly and completely described below in combination with the specific embodiments of this specification and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of this specification, not all of them. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this specification.

[0069] The technical solutions provided by the embodiments of this specification are described in detail below in conjunction with the accompanying drawings.

[0070] Figure 1A flowchart of a method for clearing files provided in this specification includes the following steps:

[0071] S101: Obtain a configuration file.

[0072] The execution subject of the file clearing method involved in this specification can be a terminal device such as a desktop computer, a laptop computer, or a server. The following only takes the terminal device as an example of the execution subject to illustrate the file clearing method in the embodiment of this specification.

[0073] In fact, in the process of executing simulation tasks through the simulation system, some intermediate result files may be generated. If these intermediate result files are not cleared in time, these intermediate result files will take up too much storage space, which may cause the execution efficiency of subsequent simulation tasks to be reduced. Therefore, the terminal device needs to clear these intermediate result files in time.

[0074] During the specific file clearing process, a configuration file can be input into the simulation system. The configuration file actually specifies the directory corresponding to the files to be cleared, the file types of the files to be cleared, and the time information of the files to be cleared, etc., which can be used as the basis for file clearing. Subsequently, the terminal device can obtain and read the configuration file to determine the content of the configuration file, and clear the above-mentioned intermediate result files according to the rules specified in the content.

[0075] In the specific implementation of this specification, the terminal device may first obtain a configuration file, and then, based on the configuration file, the terminal device may filter out files that meet the configuration file requirements from the storage space of the simulation system and clear the filtered files.

[0076] In this specification, the configuration file may specifically include the following contents: maximum number of days to save a file, target file type, file base directory, archive directory, etc.

[0077] The maximum number of days for file retention here can be used to determine the creation time range corresponding to the files to be cleared by the terminal device. The target file type can be used to indicate the file type corresponding to the files to be cleared by the terminal device. The file base directory can be used to indicate the directory corresponding to the files to be cleared by the terminal device in the specified system. The specified system here is used to store the files generated by executing simulation tasks, and the archive directory can be used to store files whose file types are not the target file types and whose status is unfinished.

[0078] For example, the content of the configuration file here can be shown in the following table.

[0079] Parameters Parameter Value Maximum number of days to save files 3 Base directory for intermediate file storage / home / simart / temp Archive Directory / home / simart / final Target file type (file suffix format) nl、cct

[0080] Table 1

[0081] It can be seen that the 3 days in the maximum file storage days in Table 1 indicates that the files to be cleared by the terminal device are files created 3 days ago, the nl and cct corresponding to the target file types indicate that the file types corresponding to the files to be cleared by the terminal device are nl and cct, / home / simart / temp is the file base directory, which is used to indicate the directory corresponding to the files to be cleared by the terminal device in the specified system, and the archive directory / home / simart / final indicates that when the terminal device clears files, it will move the files whose file types are not the target file types and whose task status is the end status to the storage location.

[0082] S102: Read the configuration file to determine file screening rules and file time information, where the file time information is used to indicate a creation time range corresponding to the files to be cleared.

[0083] S103: Determine the creation date corresponding to the file to be deleted according to the file time information.

[0084] In this specification, once the terminal device obtains the above configuration file, it can parse the configuration file and read the content in the configuration file.

[0085] In order to ensure the smooth execution of subsequent file clearing services, the terminal device can verify the content in the configuration file, specifically, the maximum number of days for file retention in the configuration file can be verified, that is, the terminal device can verify whether the maximum number of days for file retention in the configuration file is a positive number. If so, the creation date corresponding to the file to be cleared is determined based on the file time information. If not, a prompt message is returned to prompt the user to reconfirm the configuration file.

[0086] Afterwards, if the maximum number of days to save in the configuration file is a positive number, the terminal device can determine the file screening rule according to the target file type in the configuration file. Subsequently, the terminal device can perform file clearing according to the file type specified in the file screening rule, that is, the file type of the file to be cleared by the terminal device should belong to the file type specified in the file screening rule. While determining the file screening rule, the terminal device can also determine the creation time range corresponding to the files to be cleared according to the maximum number of days to save in the configuration file.

[0087] It should be noted that in the actual process, when determining the creation time range corresponding to the files that need to be cleared, in addition to determining it based on the maximum number of days the files are saved, the maximum execution time of the files in the system can also be considered. The maximum execution time of the files here can be used to indicate the longest time required for the simulation system to execute the simulation task. For a file, if the time from the creation time of the file to the current time has exceeded the maximum execution time of the file, it means that the simulation task corresponding to the file has been executed, and the file status corresponding to the file should be the end status and can be cleared.

[0088] Specifically, in order to improve the efficiency of file clearing, the terminal device will no longer clear the files that have been completed and cleared. Therefore, the terminal device can determine the end time of the creation time range corresponding to the files to be cleared based on the current date and the maximum number of days the files are kept. The terminal device can then determine the start time of the creation time range corresponding to the files to be cleared based on the end time and the maximum execution time of the above files. In this way, the terminal device can determine the creation time range corresponding to the files to be cleared based on the start time and the end time.

[0089] Continuing with the above example: the current date is November 14, 2022, 14:20, the maximum number of days for file storage is 3 days, 3 is a positive number, and the maximum execution time of the file is 7 days. When determining the creation time range corresponding to the files to be cleared, the terminal device can first determine that the end time of the creation time range is November 11, 2022 based on the current date, November 14, 2022, and the maximum number of days for file storage is 3 days. After that, the terminal device can determine that the start time of the creation time range is November 05, 2022 based on the end time and the maximum execution time of the file is 7 days. Then, based on the above start time and end time, the terminal device can determine the creation time range corresponding to the files to be cleared, that is, the creation date corresponding to the files to be cleared is November 05, 2022 to November 11, 2022.

[0090] In this way, the terminal device can flexibly clear files of a specified date and a specified file type during the file clearing process, which greatly enhances the flexibility of file clearing.

[0091] S104: different threads are set for traversal tasks of files with different creation dates, and intermediate result file directories that match the creation time range corresponding to the file time information are traversed in parallel through the set threads, wherein the intermediate result files in the intermediate result file directory are generated when executing the simulation task.

[0092] The terminal device can determine the creation date of the file to be deleted according to the creation time range determined above, and delete the file by traversing the files of each creation date.

[0093] In order to improve the efficiency of file clearing, the terminal device may set a thread for the traversal task of traversing files of each creation date, and subsequently, the terminal device may perform file clearing in parallel with multiple threads.

[0094] In addition, the terminal device can also verify the file base directory in the configuration file to ensure the smooth execution of subsequent file clearing services, that is, the terminal device can verify whether the file base directory in the configuration file is the real file directory in the specified system. If not, a prompt message is returned to prompt the configuration file to be reconfirmed.

[0095] If the terminal device can determine that the file base directory in the configuration file is the real file directory in the specified system, the terminal device can set different threads for the traversal task of traversing files with different creation dates, and through the set threads, traverse the intermediate result file directory that matches the creation time range corresponding to the file time information from the file base directory in parallel.

[0096] Continuing with the above example, whether the file base directory in the configuration file is the real file directory in the specified system, and the creation date corresponding to the files to be cleared is from November 5, 2022 to November 11, 2022, then the terminal device can set different threads for the traversal task of traversing files with a creation date of 20221105, the traversal task of traversing files with a creation date of November 6, 2022, and so on, and traverse the files with a creation date of November 5, 2022, and through the set threads, traverse in parallel to obtain the intermediate result file directory that meets the creation time range corresponding to each thread. For one of the traversal tasks, in the traversal task of the file created on November 5, 2022, it can be determined that the intermediate result file directory is / home / simart / temp / 20221105, and the intermediate result files in the intermediate result file directory include: task0001.json, task0001.json.nl, task0001.json.cct, task0002.json, task0002.json.nl, task0002.cct.

[0097] S105: Determine the intermediate result files that meet the file screening rule from the intermediate result file directory as files to be cleared.

[0098] S106: Clear the files to be cleared.

[0099] Specifically, the terminal device may determine, for each intermediate result file in the intermediate result file directory, whether the file type of the intermediate result file belongs to the target file type, and if so, the intermediate result file is treated as a file to be cleared.

[0100] However, in the actual file clearing process, in order to ensure the normal execution of the simulation task being executed, the files being executed cannot be cleared. Therefore, the terminal device needs to ensure that the task status corresponding to the file to be cleared is the end status. Therefore, the terminal device needs to determine from the intermediate result file directory the intermediate result file that meets the file screening rules (that is, the file type belongs to the target file type) and the corresponding task status is the end status as the file to be cleared.

[0101] After determining the files to be cleared, the terminal device can clear the files to be cleared.

[0102] In addition, the terminal device may also verify whether the archive directory in the configuration file is a real file directory in the specified system, and if not, create the archive directory in the specified system.

[0103] Afterwards, the terminal device can determine from the intermediate result file directory the intermediate result files that do not meet the file screening rules (i.e., the file type does not belong to the target file type) and whose corresponding task status is the end status as files to be retained, and transfer the files to be retained to the storage space under the archive directory for storage.

[0104] Continuing with the above example, the intermediate result files include: task0001.json, task0001.json.nl, task0001.json.cct, task0002.json, task0002.json.nl, task0002.cct. The archive directory in the configuration file is the real file directory in the specified system, and the file type, file creation time, number of days the file has been retained, and task status of these intermediate result files are shown in the following table:

[0105] The contents of the configuration file here can be shown in the following table.

[0106]

[0107] Table 2

[0108]

[0109] Table 3

[0110] It can be seen that for the intermediate result file task0001.json.nl, the file type is nl. Obviously, the file type nl meets the file screening rule (that is, the file type nl belongs to the target file type: nl, cct), and the task status is ended, then the intermediate result file task0001.json.nl can be used as a file to be cleared. Similarly, task0001.json.cct can also be used as a file to be cleared, and the terminal device can clear the file to be cleared.

[0111] Although the file types of task0002.json.nl and task0002.cct meet the file screening rules, the task status of these two files is solving rather than ending, so these two files cannot be used as files to be cleared.

[0112] Furthermore, since the file types of task0001.json and task0002.json are json, the file types of these two files do not meet the file screening rules (that is, the file type of json does not belong to the target file type: nl, cct), so these two files cannot be used as files to be cleared.

[0113] However, because the task status of task0001.json is ended and the file type does not meet the file screening rule, the terminal device can use the intermediate result file task0001.json as a file to be retained, and transfer the file to be retained to the storage space under the archive directory for storage.

[0114] It should be noted that in this specification, the terminal device can verify all contents in the configuration file when reading the configuration file. Only after determining that the configuration file has passed the verification, the terminal device will determine the file screening rules and file time information according to the contents in the read configuration file, and execute the subsequent remaining file clearing steps.

[0115] Specifically, after obtaining the configuration file, the terminal device may first verify the configuration file, wherein the configuration file may be verified at the following levels:

[0116] The terminal device needs to verify the maximum number of days to save and the file base directory in the configuration file. Only when the maximum number of days to save is a positive number and the file base directory is the real file directory in the specified system, the terminal device will continue to perform the subsequent file clearing business. Otherwise, the terminal device will return a prompt message to prompt reconfirmation of the configuration file. In addition, the terminal device can also verify the archive directory. When the archive directory is not the real file directory in the specified system, the terminal device needs to create the archive directory in the specified system.

[0117] It can be seen from the above method that in addition to specifying the file type of the file to be cleared, the configuration file also specifies the status of the file to be cleared. This means that during the file clearing process, in addition to clearing files of the specified file type, the status of the files to be cleared will be guaranteed to be the end state, so that the files being executed will not be cleared by mistake, which enhances the security of the file clearing process. Moreover, by clearing the intermediate result files that meet the requirements of the configuration file generated by the simulation system during the task execution process in a multi-threaded parallel manner, more storage space can be released more quickly, thereby improving the task execution efficiency of the simulation system.

[0118] The above are one or more implementation methods of this specification. Based on the same idea, this specification also provides a corresponding file clearing device, such as Figure 2 shown.

[0140] In the 1990s, improvements to a technology could be clearly distinguished as hardware improvements (for example, improvements to the circuit structure of diodes, transistors, switches, etc.) or software improvements (improvements to the method flow). However, with the development of technology, many improvements to the method flow today can be regarded as direct improvements to the hardware circuit structure. Designers almost always obtain the corresponding hardware circuit structure by programming the improved method flow into the hardware circuit. Therefore, it cannot be said that an improvement in a method flow cannot be implemented using a hardware entity module. For example, a programmable logic device (PLD) (such as a field programmable gate array (FPGA)) is such an integrated circuit whose logical function is determined by the user's programming of the device. Designers can "integrate" a digital system on a PLD by programming it themselves, without having to ask a chip manufacturer to design and produce a dedicated integrated circuit chip. Moreover, nowadays, instead of manually making integrated circuit chips, this kind of programming is mostly implemented by "logic compiler" software, which is similar to the software compiler used when developing and writing programs, and the original code before compilation must also be written in a specific programming language, which is called hardware description language (HDL). There is not only one HDL, but many kinds, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc. The most commonly used ones are VHDL (Very-High-Speed ​​Integrated Circuit Hardware Description Language) and Verilog. Those skilled in the art should also know that it is only necessary to program the method flow slightly in the above-mentioned hardware description languages ​​and program it into the integrated circuit, and then it is easy to obtain the hardware circuit that implements the logic method flow.

[0141] The controller can be implemented in any appropriate manner, for example, the controller can take the form of a microprocessor or processor and a computer-readable medium storing a computer-readable program code (such as software or firmware) that can be executed by the (micro)processor, a logic gate, a switch, an application-specific integrated circuit (ASIC), a programmable logic controller, and an embedded microcontroller. Examples of controllers include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320. The memory controller can also be implemented as part of the control logic of the memory. Those skilled in the art also know that in addition to implementing the controller in a purely computer-readable program code manner, the controller can be implemented in the form of a logic gate, a switch, an application-specific integrated circuit, a programmable logic controller, and an embedded microcontroller by logically programming the method steps. Therefore, this controller can be considered as a hardware component, and the devices included therein for implementing various functions can also be regarded as structures within the hardware component. Or even, the devices for implementing various functions can be regarded as both software modules for implementing the method and structures within the hardware component.
