Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
For technical solutions according to the invention are described, below by specific embodiment, describe.
It should be noted that, the embodiment of the present invention provides a kind of message generating apparatus, is applicable to server, and wherein, server comprises a plurality of processors and a plurality of NC, and wherein, each processor is all communicated by letter with a plurality of NC by a message generating apparatus.Wherein, NC comprises at least two the 2nd NC for protocol processes, and this message generating apparatus is connected between each the 2nd NC and processor.Meanwhile, described NC comprises the one or more NC that are connected with described message generating apparatus; Wherein, a described NC can be described the 2nd NC, can not be also described the 2nd NC.
What deserves to be explained is, the message received for described message generating apparatus, described message generating apparatus can be determined at least two the 2nd NC for protocol processes; And, for the different messages that receive, may be that same described the 2nd NC carries out protocol processes.
Thereby, when described message generating apparatus receives the message of self processor or during from the message of a NC, described message generating apparatus can realize the mirror image of message and be distributed at least two NC for protocol processes so that this message is carried out to protocol processes, and the feedback addresses comprised according to described feedback message and type of message are with to a NC or processor feedback.Thereby, in the server that comprises a plurality of processors and a plurality of NC, effectively improved the RAS of the data communication between processor and other processor.
embodiment mono-:
Fig. 3 shows the composition structure of the message generating apparatus that the present embodiment provides, and for convenience of description, only shows the part relevant to the embodiment of the present invention, and details are as follows:
A kind of message generating apparatus, described message generating apparatus comprises:
Receiving element 31, for receiving message;
In the present embodiment, receiving element 31 receives described message; Because the 2nd NC for protocol processes is a plurality of, described message is carried out to mirror image to send to a plurality of the 2nd NC simultaneously; Described the 2nd NC can generate described feedback message and feed back to the message generating apparatus in real time after completing protocol processes; After the message that receives feedback until output unit 34, processor or the described NC to appointment feeds back in real time.
As another embodiment of the present invention, receiving element 31 receives described message; When the 2nd NC for protocol processes is one, to this 2nd NC, send described message; After the message that receives this 2nd NC feedback until output unit 34, processor or the 2nd NC to appointment feeds back in real time.
As one embodiment of the invention, described message comprises: from the message of the described processor be connected with described message generating apparatus, or from the message of the one or more NC that are connected with described message generating apparatus.
It should be noted that, the described message from a NC comprises described feedback message.
Fig. 5 shows the composition structure of the server based on the message generating apparatus that the present embodiment provides, and for convenience of description, only shows the part relevant to the embodiment of the present invention,
Preferably, for above-mentioned two kinds of messages, from different interfaces, receive respectively, therefore described receiving element 31 comprises:
Express passway interconnected (QuickPath Interconnect, QPI) interface, for receiving the message of self processor;
One or more nodes interconnected (Node Interconnect, NI) interface, each described NI interface receives the message of a self-corresponding described NC.
It should be noted that, a described NI interface is connected with a described NC, and therefore, a described NI interface receives the message of a self-corresponding NC.
Like this, because the type of message of the message that carrys out self processor exists different from the type of message of message from a described NC, and/or because the data communication format of the message that carrys out self processor may exist different from the data communication format of message from a described NC, therefore, the coupling that the message generating apparatus adopts the QPI interface to carry out message to the message that carrys out self processor receives, and adopts the NI interface to mate reception to the message that carrys out a self-corresponding described NC.
Preferably, described output unit 34, specifically for:
The feedback addresses and the type of message that according to described feedback message, comprise, export described feedback message or export described feedback message from described QPI interface from described NI interface.
It should be noted that, described feedback addresses is: processor is for receiving the address of described feedback message or a described NC for receiving the address of described feedback message; Wait to get the described feedback addresses of described feedback message, by described QPI interface, send described feedback message to described processor, or send described feedback message to a corresponding described NC by certain NI interface.
It should be noted that, it is different from the type of message that described NI interface received/sent message that described QPI interface receives/send the type of message of message.Like this, feedback addresses and the type of message that need to comprise according to described feedback message, determine it is to send described feedback message by described QPI interface to processor, or determine by which described NI interface and send described feedback message to the described NC of correspondence.
embodiment bis-:
In the present embodiment, the message generating apparatus provided based on embodiment mono-, the described message of the portion received for receiving element 31, the output unit 34 that the message generating apparatus comprises is only exported a described feedback message.
Under normal circumstances, the described feedback message that same described message carries out generating after protocol processes through a plurality of described the 2nd NC should be the same, so the output unit 34 of this enforcement can only be exported the described feedback message that a described message is corresponding.
It should be noted that, when described the 2nd NC carries out protocol processes to a plurality of described messages, adopt polling mode to determine the processing sequence between a plurality of described messages.Many parts of messages that receive when receiving element 31 are data of using different operation address when completing protocol processes, many parts of described messages only carry out read/write operation to corresponding operation address in each described the 2nd NC, thereby, after message feedback unit 33 receives described feedback message, the described feedback message of output unit 34 outputs can be the same.
But, in the many parts of messages that receiving element 31 receives, exist when same operation address is carried out at least two parts of messages of read/write operation, due to the processing sequence difference of the message that same operation address is carried out to read/write operation, may produce abnormal (same described message generates different described feedback messages after protocol processes); The message handling process shown in Fig. 6 of take is example, and details are as follows:
Wherein, CPU0, CPU1 are different processors; HA is memory; NC0 is a described NC, and NC1 and NC2 are different described the 2nd NC.The NI interface of message generating apparatus and QPI interface is external NC0 and CPU0 respectively, and RdInvOwn, SnpInvOwn, WbMtoI, WbIData, SnpInvOwn, Cmp, RspI, RSPFwdI_DataM, DataC_M, RspFwdI, Cmp, WBIData, WBCmp, DataC_E_Cmp are message; CPU1 is for certain address reading data from CPU0 (CPU1 is from the message flow of the operation of certain address reading data of CPU0 to as shown in the dotted line as Fig. 6), send RdInvOwn to memory, then memory sends SnpInvOwn to NC0, and then the receiving element 31 of message generating apparatus receives from the NI interface SnpInvOwn that NC0 sends.CPU0, in order to write data (CPU0 writes the message flow of operation of data to as shown in the solid line as in Fig. 6 to HA) to HA, sends WbIData, WbMtoI to the message generating apparatus; The receiving element 31 of message generating apparatus receives from the QPI interface WbIData, the WbMtoI that CPU0 sends;
After if allocation units 32 are all distributed to respectively NC1 and NC2 by SnpInvOwn, WbIData and WbMtoI simultaneously, no matter be in NC1 or NC2, from the WbIData of CPU0 with from the SnpInvOwn of NC0, need to use same operation address complete protocol processes; Meanwhile, NC1 or NC2 adopt polling mode to determine the processing sequence of WbIData and SnpInvOwn.Because NC1 first processes the WbIData from CPU0 from the SnpInvOwn reprocessing of NC0, NC1 is to message generating apparatus feedback SnpInvOwn, output unit 34 according to the type of message of SnpInvOwn and feedback addresses (CPU0) by the QPI interface to CPU0 output SnpInvOwn with from this certain address reading data, after NC1 handles WbIData, directly by the QPI interface, to CPU0 output Cmp(, finish CPU0 and write the operation of data to HA, but unrealized this operation) with; Then, CPU0 sends RspI by the QPI interface to the message generating apparatus, the message generating apparatus completes NC1 the RSPFwdI_DataM generated after protocol processes and feeds back to NC0 by the NI interface, then, NC0 finishes the operation of CPU1 to certain address reading data of CPU0 to CPU1 feedback DataC_M(, and has realized this operation).Because NC2 first processes the SnpInvOwn from NC0 from the WbIData reprocessing of CPU0, NC2 is to message generating apparatus feedback WBIData, output unit 34 is according to type of message and the feedback addresses (NC0) of WBIData, send WBIData by the NI interface to NC0, then, NC0 writes data with realization to the assigned address in HA to HA transmission WbMtoI and WbIData, then HA feeds back Cmp to NC0, then the NI interface of message generating apparatus receives the WBCmp that NC0 sends, the message generating apparatus completes NC2 the Cmp feedback CPU0 generated after protocol processes, then the message generating apparatus completes the RspI that generates after the SnpInvOwn of protocol processes from NC0 by NI interface feedback NC0 by NC2, then NC0 feeds back RspI to HA, then HA finishes the operation of CPU1 to certain address reading data of CPU0 to CPU1 feedback DataC_E_Cmp(, but unrealized this operation).
Because NC1 first processes the WbIData from CPU0 from the SnpInvOwn reprocessing of NC0, it is SnpInvOwn that SnpInvOwn is completed to the message generated after protocol processes, and it is Cmp that WbIData is completed to the message generated after protocol processes; Because NC2 first processes the SnpInvOwn from NC0 from the WbIData reprocessing of CPU0, it is RspI that SnpInvOwn is completed to the message generated after protocol processes, and it is WBIData that WbIData is completed to the message generated after protocol processes.Thereby cause CPU1 to write the operation failure of data to HA to operation failure or the CPU0 of certain address reading data of CPU0.
Thereby, in the many parts of messages that receiving element 31 receives, exist when same operation address is carried out at least two parts of messages of read/write operation, output unit 34 may be exported different described feedback messages, cause the server None-identified, also can't realize a plurality of for realizing backup mutually between the 2nd NC of protocol processes in same server.
For this reason, only export a described feedback message in order to guarantee output unit 34, and accessing same operation address for fear of needs is assigned with unit 32 with a plurality of messages that complete protocol processes simultaneously and is assigned to the 2nd NC, Fig. 4 shows the composition structure of another message generating apparatus that the present embodiment provides, for convenience of description, only show the part relevant to the embodiment of the present invention.
As one embodiment of the invention, described message generating apparatus also comprises:
Judging unit 42, if do not store the operation address of the described message that described receiving element 31 receives for described address list unit 41, by described allocation units 32, described message is carried out to mirror image to be sent at least two the 2nd NC, and preserve the operation address of the described described message received in described address list unit 41.
Preferably, described operation address is specially: the memory address of putting down in writing in described message, need to access while carrying out protocol processes.
It should be noted that, distribute at least two described the 2nd NC to carry out all described message of protocol processes for allocation units 32, until, before each described the 2nd NC all feeds back described feedback message, described address list unit 41 stores the operation address that described message is corresponding always; That is,, after all described the 2nd NC have fed back described feedback message, just can be in address list unit 41 delete the operation address that does not carry out the described message before protocol processes that described feedback message is corresponding.
Like this, rigidly connect the described message of receiving for receiving element 31, extract the operation address of described message from described message; If judging unit 42 does not find the operation address identical with the operation address of the described message received after traveling through in address list unit 41 and searching, in address list unit 41, add the operation address of the described message received; Meanwhile, carry out allocation units 32 to allow a plurality of described the 2nd NC described message be carried out to protocol processes simultaneously.
Preferably, meanwhile, described message generating apparatus also comprises:
Described wait unit 43, for adding at waiting list the described message that described receiving element 31 receives;
Described judging unit 42, also for:
If described address list unit 41 has stored the operation address of the described message that described receiving element 31 receives, by described wait unit 43, in waiting list, added the described message that described receiving element receives.
It should be noted that, when the operation address of the described message in described waiting list is deleted in described address list unit 41, carry out allocation units 32 so that described the 2nd NC carries out protocol processes to described message.
Like this, for rigidly connecting operation address corresponding to described message of receiving, the situation of identical recordings has been arranged in described address list unit 41, judging unit 42 jumps to waits for unit 43 execution, the described message received is added in waiting list simultaneously.
Preferably, when allocation units 32 are distributed to described message a plurality of the 2nd NC and are carried out protocol processes, for the described feedback message that guarantees each described the 2nd NC feedback is all the same, described allocation units 32, also for:
Specify the resource of each described the 2nd NC for carrying on an agreement and processing, record resource number corresponding to described resource.
It should be noted that, the described resource of processing for carrying on an agreement comprises the software and hardware resources that operation address that needs access, storage resources, cache resources etc. are required for the processing procedure that carries on an agreement.The described resource number of record in allocation units 32, for identifying described the 2nd NC required resource while processing that carries on an agreement.
Like this, after described allocation units 32 complete the appointment of described resource, the resource that each described the 2nd NC processes for carrying on an agreement (processing procedure that especially carries on an agreement needs the operation address of access) is the same, thereby the described feedback message generated is also the same.
Preferably, the described feedback message produced due to each described the 2nd NC is the same, and described message generating apparatus also comprises:
It should be noted that, the described feedback message that same described message generates after described the 2nd NC carries out protocol processes has same message characteristic value; And described message characteristic value is documented in described feedback message.
Like this, for to same described message, although it is different to the time of advent of message feedback unit 33 that above-mentioned all described the 2nd NC feed back described feedback message,, output unit 34 only sends the described message feedback unit 33 described feedback message that at first once (for the first time) receives; In this simultaneously, the message characteristic value of the described feedback message that filter element 44 records once arrive at first, so that filter out the described feedback message that described message that receive later, same generates through protocol processes.
Preferably, described filter element 44, also for:
If described message feedback unit 33 receives described feedback message for the last time, delete the message characteristic value of described feedback message, from described address list unit 41, delete at the operation address of the message before processing and generate described feedback message that carries on an agreement.
Like this, for all described the 2nd NC that same described message is carried out to protocol processes, message feedback unit 33 has all been received the feedback message of each described the 2nd NC feedback, thus the message characteristic value of deleting described feedback message; Meanwhile, delete the operation address of the message before processing that carrying on an agreement that described feedback message is corresponding in described address list unit 41.
Meanwhile, exist in waiting list with described message and need same operation address when completing the message of protocol conversion, after allocation units 32 carry out mirror image by this waits queue, message that use same operation address, a plurality of the 2nd NC of transmission are with the processing that carries on an agreement; Thereby, effectively avoided the 2nd NC to carry out protocol processes to a plurality of messages that use same address simultaneously, guaranteed that the feedback message that same message carries out generating after protocol processes is the same.
As one embodiment of the invention, through Preset Time, the message characteristic value of deleting described feedback message, from described address list unit 41, delete at the operation address of the message before processing and generate described feedback message that carries on an agreement.
Make mistakes and, not in time to the described feedback message of message feedback unit 33 feedback, preset described Preset Time for fear of certain the 2nd NC for protocol processes.Another purpose that presets described Preset Time is: after described Preset Time, the protocol processes that means this message finishes, for fear of affecting in waiting list, use the message that needs same operation address with described message, allocation units 32 in this wait queue, message that use same operation address to be carried out sending a plurality of the 2nd NC with the processing that carries on an agreement after mirror image in time.
