In this embodiment, the first core cluster is any one of a plurality of core clusters of the many-core system, the second core cluster is any one of the core clusters except the first core cluster in the many-core system, and the number of the second core clusters may be one or more.
In the core sharing method based on the many-core system provided by the embodiment of the disclosure, in a service scenario where the many-core system includes multiple core clusters, for multiple core clusters with a cross-cluster service requirement, by using any one core cluster or at least one second processing core in the multiple core clusters as a shared core among the multiple core clusters, the multiple core clusters can share data of the shared core (for example, parameters required in a deep learning network, and the like), so that the cross-cluster service among the multiple core clusters of the many-core system is realized, the requirement that the multiple core clusters need to share data of some processing cores is met, the control capability of the processing cores of the many-core system is improved, and the flexibility of the many-core system in task processing is improved.
Fig. 2 is a block diagram of a many-core system according to an embodiment of the disclosure, and in the embodiment of the disclosure, referring to fig. 2, each core cluster has a main processing core, and the main processing core is a second processing core pre-designated in at least one second processing core of the core cluster. The core sharing method of the embodiment of the disclosure may be applied to a main processing core of any core cluster in a many-core system, that is, the core sharing method of the embodiment of the disclosure is implemented based on the main processing core of any core cluster, and the main processing core may be used to process a task corresponding to the core cluster where the main processing core is located, and may also be used to perform task allocation and management in the cluster.
In some embodiments, when at least one second core cluster in the many-core system needs to use data (e.g., parameters) of one or more second processing cores in the first core cluster, then the main processing core of the second core cluster may send a core sharing request to the main processing core of the first core cluster, where the core sharing request may include, but is not limited to: identification information and address information corresponding to the second core cluster, information of one or more second processing cores in the first core cluster to be shared, and the like. In this case, in step S1, the primary processing core of the first core cluster receives the core sharing request sent by the primary processing core of the second core cluster, where the primary processing core of the second core cluster is a second processing core pre-designated in at least one second processing core of the second core cluster.
In some embodiments, referring to fig. 2, the many-core system includes a plurality of processing cores, where one processing core is designated as a first processing core in advance, and the other processing cores are second processing cores, the first processing core is configured to receive a to-be-processed task sent from an external host, and build a core cluster for processing the to-be-processed task in the many-core system, and the to-be-processed task is scheduled and managed in the many-core system.
When an external host or a first processing core needs to establish or allocate a common task to a plurality of core clusters, the external host or the first processing core may select any one of the plurality of core clusters as a first core cluster, and the remaining core clusters as second core clusters, the external host or the first processing core may first send a core sharing request to a main processing core of the first core cluster, where the core sharing request may include, but is not limited to, the common task, identification information and address information corresponding to the second core cluster, so that the main processing core of the first core cluster establishes a shared core for processing the common task. In this case, in step S1, the main processing core of the first core cluster receives a core sharing request sent by the external host or the first processing core, where the core sharing request is generated by the external host or the first processing core based on the common task corresponding to the first core cluster and the second core cluster.
The common task refers to a task that both the first core cluster and the second core cluster need to execute, for example, the first core cluster needs to execute a fast fourier transform task (FFT) and a window function filtering task, and the second core cluster needs to execute a fast fourier transform task (FFT) and a frequency domain multiplication task, so that the fast fourier transform task (FFT) is the common task corresponding to the first core cluster and the second core cluster, for example, the common task may be a complex mathematical operation (such as matrix decomposition, FFT, etc.) task in a backbone network of a neural network.
In some embodiments, in step S2, after receiving the core sharing request from the primary processing core of the second core cluster, the primary processing core of the first core cluster determines at least one second processing core from at least one second processing core of the first core cluster in which the primary processing core of the first core cluster is located according to the core sharing request, where the determined second processing core serves as a sharing core, and the at least one sharing core constitutes a sharing core array. The number of shared cores may be specifically determined according to the number of second processing cores requested to be shared by the main processing core of the second core cluster, which is not limited in this disclosure. Therefore, the cluster-crossing service among a plurality of core clusters is realized, the requirement that a plurality of core clusters need to share data of some processing cores is met, and the control capability of part of processing cores (such as the main processing core of the core cluster) in the many-core system and the flexibility of task processing of each cluster are improved.
In some embodiments, in step S2, after receiving the core sharing request from the external host or the first processing core in the many-core system, the main processing core of the first core cluster determines at least one second processing core from among at least one second processing core of the first core cluster in which the main processing core is located according to the core sharing request, where the determined second processing core serves as a shared core, and the at least one shared core constitutes a shared core array. The number of the shared cores may be specifically determined according to the resource demand required by the common task, which is not limited in this embodiment of the disclosure as long as the total remaining resource amount of the constructed shared cores can meet (is greater than or equal to) the resource demand required by the common task.
The resource demand required by the common task refers to the amount of resources required when the common task is executed, and the resources may be, for example, computing resources, storage resources, and bandwidth resources. For a plurality of core clusters needing to process common tasks, shared cores among the plurality of core clusters are established for processing the common tasks, so that the processing efficiency and flexibility of the tasks are improved, cross-cluster services among the plurality of core clusters of a many-core system are realized, and the requirement that the plurality of core clusters need to share data of some processing cores is met.
In some embodiments, the primary processing core of the first core cluster selects the idle second processing core as the shared core. In some embodiments, in a case where a core sharing request of a primary processing core of a second core cluster is received, if there is no idle second processing core in a first core cluster in which the second core cluster is located, a core sharing request failure message is returned to the primary processing core of the second core cluster. In some embodiments, in a case where a core sharing request of an external host or a first processing core is received, if there is no idle second processing core in a first core cluster in which the core sharing request of the external host or the first processing core is located, a core sharing request failure message is returned to the external host or the first processing core.
In some embodiments, in step S2, after receiving the core sharing request from the first processing core in the external host or the many-core system, the main processing core of the first core cluster determines at least one second processing core from among at least one second processing core of the second core cluster according to the core sharing request, and the determined second processing core serves as a shared core between the first core cluster and the second core cluster. In some embodiments, in step S2, after receiving the core sharing request from the first processing core in the external host or the many-core system, according to the core sharing request, if there is no available (idle) second processing core in the first core cluster in which the main processing core of the first core cluster is located, the main processing core of the first core cluster determines at least one second processing core from among at least one second processing core of the second core cluster, and the determined second processing core serves as a shared core between the first core cluster and the second core cluster.
Specifically, determining at least one second processing core from among at least one second processing core of the second core cluster to serve as the shared core specifically includes: and sending a core sharing request to the main processing core of the second core cluster, so that the main processing core of the second core cluster determines at least one second processing core from at least one second processing core of the core cluster where the main processing core of the second core cluster is located in response to the core sharing request, and the at least one second processing core is used as a sharing core.
It should be noted that, in the embodiment of the present disclosure, the "first" and the "second" in the first core cluster and the second core cluster are only used to distinguish different core clusters, and do not refer to a certain core cluster in particular, in a many-core system, all the core clusters have equal positions, and can be used as the first core cluster to receive a core sharing request, and execute a core sharing method in response to the core sharing request, and each core cluster in all the core clusters can also be used as the second core cluster to request core sharing from other core clusters.
In some embodiments, after receiving a core sharing request from a first processing core in an external host or a many-core system, a main processing core of a first core cluster determines at least one second processing core from at least one second processing core of the first core cluster where the main processing core is located as a shared core according to the core sharing request, and determines at least one second processing core from the at least one second processing core of the second core cluster as a shared core. In other words, a portion of the second processing cores from the first core cluster is screened, and a portion of the second processing cores from the second core cluster is screened, collectively as a shared core.
In some embodiments, after determining the second processing core as the shared core, the primary processing core of the first core cluster or the second core cluster further marks the second processing core to mark the second processing core as shared for managing cores in the cluster.
Fig. 3 is a flowchart of another core sharing method according to an embodiment of the present disclosure.
Referring to fig. 3, for convenience of management, in some embodiments, after determining the shared core, the core sharing method further includes:
step S3, updating core cluster lists corresponding to the shared cores, where the updated core cluster lists include identification information corresponding to the first core cluster and the second core cluster, respectively.
As an example, before sharing, each second processing core in each cluster pre-stores a core cluster list corresponding to the core cluster in which each second processing core is located, where the core cluster list includes, but is not limited to: identification information corresponding to a core cluster where the second processing core is located, and information of each member in the cluster, where the information of each member in the cluster includes but is not limited to: identification, address, location, etc. of each member. As an example, after the shared core is determined by the main processing core of the first core cluster, the identification information corresponding to the second core cluster is added to the core cluster list of each shared core, so as to update the core cluster list corresponding to each shared core, where the updated core cluster list includes the identification information corresponding to each of the first core cluster and the second core cluster, so that the shared core can identify that the subsequent job belongs to the first core cluster or the second core cluster, and perform corresponding processing.
In some embodiments, after determining the shared core, the primary processing core of the first core cluster further feeds back information of the shared core, including but not limited to an identifier of the shared core, address information, and the like, to the second core cluster, so that the processing cores in the second core cluster can access the shared core to obtain required data, or to perform required services through the shared core, and the like.
In some embodiments, in a case of receiving a core sharing request sent by an external host or a first processing core, if a main processing core of a first core cluster sends the core sharing request to a main processing core of a second core cluster, after determining a shared core, the main processing core of the second core cluster further feeds back information of the shared core to the first core cluster, where the information includes, but is not limited to, an identifier of the shared core, address information, and the like, so that processing cores in the first core cluster can access the shared core to obtain required data, or find required traffic through the shared core, and the like.

Referring to fig. 4, in some embodiments, to effectively solve the problem that a shared core conflicts in writing data to different core clusters, after determining the shared core array, the core sharing method further includes:
and step S4, judging whether an available storage space exists in the storage area corresponding to the shared core array, if so, executing step S5, otherwise, executing step S7.
In some embodiments, after determining that the available storage space exists in the storage area corresponding to the shared core array, it may further determine whether the memory capacity of the available storage space is greater than or equal to a preset memory capacity, if so, perform step S5, otherwise, perform step S7. The storage area corresponding to the shared core array is the storage area of all shared cores in the shared core array.
Step S5, a first shared memory area corresponding to the first core cluster is created in the memory area corresponding to the shared core array.
