Detailed Description
The present invention will now be described in further detail with reference to the drawings and examples, it being understood that the specific embodiments herein described are merely illustrative of and not restrictive on the broad invention, and it should be further noted that for the purposes of description, only some, but not all, of the structures associated with the present invention are shown in the drawings.
Fig. 1 shows specific application scenarios applied by the solution of the embodiment of the present invention, referring to fig. 1, the supercomputing platform includes a board jump machine 101, a debugging cluster 102, a ferry machine 103, a supercomputing cluster 104, a storage node 105 of the supercomputing platform, and a management subsystem set (not shown).
The trigger 101 is used for accessing a public network user, and the debugging cluster 102 is used for a user to log in one way through the trigger 101 and complete debugging operation of related tasks. The supercomputing cluster 104 is used to actually perform user tasks, typically tasks that a user has debugged without problems by debugging the cluster 102. The storage node 105 is used for storing data, and the data includes program files corresponding to tasks, data operated by the tasks and execution results. The storage nodes 105 are accessible by the debug cluster 102 and the supercomputing cluster 104 as a basis and object for debugging the cluster 102 and supercomputing cluster 104 to perform tasks.
Fig. 2 shows a flowchart of an -type supercomputing platform upload data ferrying method provided by an embodiment of the present invention, which specifically includes the following steps:
step S201: the user uploads data through the trigger 101.
The data uploaded by the user may include program files, document files, etc. that are needed for subsequent execution of the program on the debug cluster 102 or the supercomputing cluster 104.
In order to ensure safety, the data of the user cannot be directly uploaded to the storage node of the super computing platform. But rather buffered and ferred by ferry 103.
Specifically, referring to fig. 3, the storage space D1 of the ferry 103 is mounted on the directory D1' of the ramp machine 101. The user on the diving board machine 101 can upload data onto the directory D1', i.e., the data is stored in the storage space D1 of the ferry machine 103. The storage space D2 of the storage node 105 on the supercomputing platform is mounted on the directory D2' of the ferry 103.
Step S102: the ferrying machine 103 ferries the data uploaded by the user to a storage node 105 in the supercomputing platform.
Specifically, the ferry machine 103 may copy the data in the storage space D1 to the directory D2', that is, the transmission of the upload data from the ferry machine 103 to the storage node 105 may be completed, and this process may be referred to as "ferry" of the upload data.
After the data is uploaded to the storage node 105, both the debug cluster 102 and the supercomputing cluster 104 can access the data. The user can debug the program file by using the debugging cluster 102, and debug errors which may occur in the running process, especially execution errors which are often caused by mismatching of the execution environments. After the user debugs without errors, the program may be actually executed by the user on the supercomputing cluster 104.
Between two consecutive ferry operations of the ferry 103 on the uploaded data of different users, the data transmission can be suspended intervals to reduce the load of the processor.
Each time the ferry machine 103 ferries the uploaded data of different users, different ferry time slot lengths can be set, and the longer the ferry time slot length is, the more the data amount of the uploaded data can be transmitted to the user, and actually different priorities are set for the user. The time slot lengths allocated by the ferry machine 103 for ferry operation of users with different priorities are different.
The longer a slot length is allocated to a user, the more data can theoretically be ferred to the storage node for that user in each cycle period.
For example, fig. 4 shows a schematic diagram of priority policies for ferrying data of two users, where the horizontal axis t in fig. 4 represents time slots of ferry data operations respectively allocated to different users, it is obvious that, among the users a, B and C, the time slot of the ferry data operation allocated to the user B is relatively long, and therefore, the priority of the user B is relatively high, and the user B is ferred to more data on the storage node in each ferry period.
An interval rest time can be set between the ferrying operations of the ferrying machine 103 on the uploaded data of two adjacent users, so that the processor is prevented from being in high-load operation for a long time. For example, fig. 5 shows a schematic diagram of adding a set interval rest time to the timeslot setting machine of fig. 4. There is an interval rest time length t1 between ferry operations on user a, user B, and user C's data.
In order to deal with the situation that a user may upload a file with a large data volume, the ferry machine 103 temporarily does not delete ferry-finished data from the storage space D1 of the ferry machine 103 every time the ferry machine 103 ferry the uploaded data to the storage node 105, because for the file with the large data volume, the ferry machine 103 often performs data ferry operation after the file is not completely transmitted, the ferry-finished data is only partial data in the complete file data, deletes the file from the ferry machine 103 after the ferry is finished, the subsequent uploading of the uploaded residual data by the user fails, but keeps the file data uploaded by the user in the ferry machine 103 at all times and is not reasonable, because the size of the storage space in the ferry machine 103 is limited, an aging time mechanism can be added for performing reasonable space recycling operation on the storage space in the ferry machine, the file storage time in the storage space of the ferry machine 103 is periodically performed, the aging time exceeds the latest aging time, and the storage space in the ferry machine 103 is not subjected to the aging, and the aging time exceeds the latest aging time, and the aging time of the file is released, so that the file is not recovered.
When the ferry 103 carries out regular inspection and space recovery processing on files in the storage space of the ferry, problems need to be considered, namely, how to carry out space recovery processing on the files if the files are uploaded by a user, the particularity of the files is that the files are updated along with each operation of viewing the files at the modification time, the modification time is not , the files can update the modification date only when the files are actually modified, and therefore the space recovery processing on the files needs to be additionally designed solutions can be that after the ferry 103 carries out space recovery processing on the files in the storage space of the ferry, empty files in the storage space are scanned (namely, no files exist in directories and sub-directories), and deletion operation is carried out on the empty files.
The aging time threshold may be the same for all users, or may be adjusted according to the actual situation of the user. Such as an excessive number of files uploaded by a user in the storage space of ferry 105, may result in a degradation of system performance, and for this reason the setting of the aging time threshold may be related to the number of files of the user in the storage space, for example, the size of the aging time threshold may decrease continuously or in steps as the number of files of the user increases. Therefore, the aging time threshold of the user with the larger number of user files is smaller, and as a result, the uploaded data of the part of users can be cleaned more timely, so that the influence on the system performance is reduced.
in an alternative embodiment, the storage space D2 of the storage node 105 to which the ferry 103 ferry the user data may be public storage spaces, and the user should also transfer the files in the storage space D2 to their own work directory (such as the Home directory of the user) before actual use, so that the ferry operation of the ferry 103 actually ferries the files uploaded by the user from their own storage space D1 to the public storage space D2 of the storage node 105, and in view of the safety problem, through the authority design, the user can still only see the data uploaded by himself although accessing the public storage space D2, the above-mentioned file space recycling mechanism for the storage space on the ferry 103 is also applicable to the public storage space D2. of the storage node 105, and can realize a complete -based space recycling operation result of the ferry 103 and the storage node 105 by means of the synchronization mechanism between the storage space D1 and the storage space 105 of the ferry 103.
Through the scheme of the embodiment, the user does not have the right to directly upload the data to the storage node of the supercomputing platform, but the ferrying machine carries out data ferrying operation, and therefore the safety of the data can be improved.
FIG. 6 is a flow chart showing the input ferrying method for downloading data of super computing platforms, which completes the downloading operation of user files, according to the present invention, and referring to FIG. 6, the method includes the following steps:
step S601, the user downloads the data to be downloaded from the storage node 105 to the th storage space of the ferry 103 through the operation on the debugging cluster 102.
Fig. 7 shows a memory mount diagram of a user data download process. The data to be downloaded by the storage node 105 user is stored in storage space D3. The storage space D3 may actually be the user's Home directory. At the debugger cluster 102, the storage space D3 is mounted on the directory D3' of the debugger cluster 102, and the ferry 103 has two storage spaces D4 and D5 for storing data downloaded by the user. The storage space D4 is mounted on the directory D4 'of the debug cluster 102, and the storage space D5 is mounted on the directory D5' of the ramp 101. The user, through the download operation on the commissioning cluster 102, appears to copy and download the files in the operation directory D3 'into the directory D4', but actually copies the data from the storage space D3 of the storage node 105 to the storage space D4 of the ferry 103.
In the scenario of fig. 7, the storage space D4 on the ferry 103 corresponds to the th storage space, and the th storage space is used for the data downloaded from the storage node 105, but the downloaded data is not directly acquired by the user for a while, and a data ferry operation from the storage space D4 on the ferry 103 to the storage space D5 (i.e., the second storage space) is also required.
Step S602, the ferrying machine 103 ferries the data downloaded by the user in the th storage space to the second storage space.
In the scenario of fig. 7, the second storage space is storage space D5 on ferry 103. The data downloaded by the user will be ferred from the storage space D4 into the storage space D5. Since the storage space D5 is mounted on the directory D5' of the springboard machine 101, when the data is ferred to the storage space D5, the user can see and obtain the data through the springboard machine 101.
For example, each time downloading data of different users is ferried, different ferrying time slot lengths can be set, the longer the ferrying time slot length is, the more data quantity of the data which can be transmitted to the user is, different priorities are actually set for the users, interval rest time can be set between the downloading data of two adjacent users to avoid that the processor runs under high load for a long time, for the data downloaded by the users, a space recycling mechanism can be introduced into the ferrying machine, the file storage time in the storage space (including storage space and the second storage space) of the ferrying machine is periodically checked, and the files with the latest modification time exceeding the aging time threshold are deleted to release the storage space, after the ferrying machine 103 carries out space recycling processing on the files in the storage space, empty folders in the storage space (namely, directories and the files do not exist in the storage space), the deleting operation on the empty folders can be carried out deleting operation, the size of all files can be adjusted according to the aging time of the users, and the aging time of all the files can be reduced continuously according to the situation that the user is small.
Step S603: the user obtains the data downloaded by the user through the directory mounted on the springboard machine 103 through the second storage space of the ferry machine 103.
Through the scheme of the embodiment, the user does not have the right to directly download the data from the storage node of the super computing platform, but the ferrying machine carries out data ferrying operation, and therefore the safety of the data can be improved.
Please note that the above description is only for the preferred embodiment of the present invention and the technical principles employed. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments illustrated herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention.
