In order that the objects, technical solutions and advantages of the present invention become more apparent, below in conjunction with drawings and Examples, right
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only in order to explain the present invention, and
It is not used in the restriction present invention.
In order to technical solutions according to the invention are described, to illustrate below by specific embodiment.
It should be noted that the embodiment of the present invention provides a kind of message generating means it is adaptable to server, wherein, service
Device includes multiple processors and multiple nc, and wherein, each processor is all communicated with multiple nc by message generating means.Its
In, nc includes at least two the 2nd nc being used for protocol processes, and this message generating means is connected to each the 2nd nc and place
Between reason device.Meanwhile, described nc includes the one or more nc being connected with described message generating means；Wherein, institute
Stating a nc can be for described 2nd nc it is also possible to not be described 2nd nc.
What deserves to be explained is, the message that described message generating means are received, described message generating means can determine whether
At least two the 2nd nc being used for protocol processes；And, for the different messages receiving it may be possible to same described 2nd nc enters
Row protocol processes.
Thus, when described message generating means receive the message from processor or the message from a nc, institute
State message generating means be capable of the mirror image to message and be distributed at least two for protocol processes nc with to this message
Carry out protocol processes, the feedback addresses including according to described feedback message and type of message are with to a nc or processor feedback.
Thus, in including the server of multiple processors and multiple nc, it is effectively improved between processor and other processor
Data communication ras.
Embodiment one:
Fig. 3 show the present embodiment provide message generating means composition structure, for the ease of description, illustrate only with
The related part of the embodiment of the present invention, details are as follows:
A kind of message generating means, described message generating means include:
Receiving unit 31, for receiving message；
Allocation unit 32, for carrying out mirror image to send at least two the 2nd nc by described message；
Message feedback unit 33, for receiving the feedback message of described 2nd nc feedback, described feedback message is by described the
Two nc carry out to described message generating after protocol processes；
Output unit 34, for exporting described feedback message.
In the present embodiment, receiving unit 31 receives described message；Because the 2nd nc for protocol processes is multiple, then
Described message is carried out mirror image to send to multiple 2nd nc simultaneously；Described 2nd nc can generate described anti-after completing protocol processes
Feedback message simultaneously feeds back to message generating means in real time；After unit 34 to be output receives the message of feedback, in real time to specified place
Reason device or a described nc feedback.
As another embodiment of the present invention, receiving unit 31 receives described message；When the 2nd nc for protocol processes is
When one, send described message to this 2nd nc；After unit 34 to be output receives the message of this 2nd nc feedback, in real time
To specified processor or the 2nd nc feedback.
As one embodiment of the invention, described message includes: from the described process being connected with described message generating means
The message of device, or the message from the one or more nc being connected with described message generating means.
It should be noted that the described message being derived from a nc includes described feedback message.
Fig. 5 shows the composition structure of the server based on message generating means that the present embodiment provides, for the ease of retouching
State, illustrate only the part related to the embodiment of the present invention,
Preferably, for above two message, respectively from different interface, therefore described receiving unit 31 wraps
Include:
Quick Path Interconnect (quickpath interconnect, qpi) interface, for receiving the report from processor
Literary composition；
One or more nodes interconnect (node interconnect, ni) interface, and it is right that each described ni interface is derived from
The message of the described nc answering.
It should be noted that described ni interface nc described with is connected, therefore, a described ni interface
Receive the message of a self-corresponding nc.
So, because the type of message of the message from processor is deposited with the type of message of the message from a described nc
In difference, and/or the data communication format due to the message from processor is logical with the data of the message from a described nc
Letter form there may be difference, therefore, message generating means using qpi interface the message from processor is carried out message
Connect receipts, coupling is carried out to the message carrying out a self-corresponding described nc using ni interface and receives.
Preferably, described output unit 34, specifically for:
The feedback addresses being included according to described feedback message and type of message, export described feedback message from described ni interface
Or export described feedback message from described qpi interface.
It should be noted that described feedback addresses are: processor is used for receiving the address or described the of described feedback message
One nc is used for receiving the address of described feedback message；Described feedback addresses to described feedback message to be obtained, by described qpi
Interface sends the described message that feeds back to described processor, or it is extremely corresponding described to send described feedback message by certain ni interface
First nc.
It should be noted that the type of message of described qpi interface/transmission message and described ni interface/transmission
The type of message of message is different.As such, it is desirable to feed back, according to described, feedback addresses and the type of message that message includes, determination is logical
Cross described qpi interface and send described feedback message to processor, or determine by which described ni interface to corresponding described the
One nc sends described feedback message.
Embodiment two:
In the present embodiment, the message generating means being provided based on embodiment one, that receiving unit 31 is received
The described message of part, the output unit 34 that message generating means comprise only exports a described feedback message.
Under normal circumstances, the described feedback that same described message generates after multiple described 2nd nc carry out protocol processes
Message should be the same, and the output unit 34 of therefore this enforcement can only export the corresponding described feedback report of a described message
Literary composition.
It should be noted that when described 2nd nc carries out protocol processes to multiple described messages, using polling mode
Determine the processing sequence between multiple described messages.When the many parts of messages that receiving unit 31 receives are using different operations
When the data of address is to complete protocol processes, many parts of described messages only enter to corresponding operation address in each described 2nd nc
Row read/write operation, thus receiving after described feedback message after message feedback unit 33, the described feedback of output unit 34 output
Message can be the same.
But, when existing in the many parts of messages that receiving unit 31 receives, read/write operation is carried out to same operation address
During at least two parts of messages, the processing sequence due to same operation address is carried out with the message of read/write operation is different, may produce
Abnormal (same described message generates different described feedback messages after protocol processes)；With the Message processing stream shown in Fig. 6
As a example journey, details are as follows:
Wherein, cpu0, cpu1 are different processors；Ha is memory；Nc0 is a described nc, nc1 and nc2 is not
Same described 2nd nc.The ni interface of message generating means and qpi interface external nc0 and cpu0 respectively, rdinvown,
snpinvown、wbmtoi、wbidata、snpinvown、cmp、rspi、rspfwdi_datam、datac_m、rspfwdi、
Cmp, wbidata, wbcmp, datac_e_cmp are message；Cpu1 in order to from certain address reading data of cpu0 (cpu1 from
The message of the operation of certain address reading data of cpu0 flows to as shown in the dotted line in Fig. 6), send to memory
Rdinvown, then memory to nc0 send snpinvown, then the receiving unit 31 of message generating means connect from ni interface
Receive the snpinvown that nc0 sends.In order to write data to ha, (cpu0 writes the message flow direction of the operation of data as in Fig. 6 to cpu0 to ha
Shown in solid), to message generating means send wbidata, wbmtoi；The receiving unit 31 of message generating means connects from qpi
Mouth receives wbidata, wbmtoi that cpu0 sends；
If allocation unit 32 snpinvown, wbidata and wbmtoi is respectively allocated to after nc1 and nc2, no simultaneously
By being in nc1 or nc2, the wbidata from the cpu0 and snpinvown from nc0 be all need using same operatively
Location completes protocol processes；Meanwhile, nc1 or nc2 is the process determining wbidata and snpinvown using polling mode
Sequentially.Post-process the wbidata being derived from cpu0 because nc1 is first processed from the snpinvown of nc0, then nc1 generates dress to message
Put feedback snpinvown, output unit 34 passes through qpi interface according to the type of message of snpinvown and feedback addresses (cpu0)
To cpu0 output snpinvown from this certain address reading data, to have processed after wbidata after nc1, directly connect by qpi
Mouth terminates, to cpu0 output cmp(, the operation that cpu0 writes data to ha, but is not implemented this operation) with；Then, cpu0 passes through
Qpi interface sends rspi to message generating means, and nc1 is completed the rspfwdi_ generating after protocol processes by message generating means
Datam feeds back to nc0 by ni interface, and then, nc0 terminates cpu1 certain address to cpu0 to cpu1 feedback datac_m(
Read the operation of data, and achieve this operation).Because the wbidata post processing that nc2 is first processed from cpu0 is derived from nc0's
Snpinvown, then nc2 to message generating means feed back wbidata；Output unit 34 is according to the type of message of wbidata and anti-
Feedback address (nc0), sends wbidata by ni interface to nc0, and then, nc0 sends wbmtoi and wbidata to realize to ha
Write data to the specified address in ha, then ha feeds back cmp to nc0, then the ni interface of message generating means is sent out to nc0
The wbcmp sending, nc2 is completed the cmp feedback cpu0 generating after protocol processes by message generating means, and then message generating means will
The rspi that nc2 completes to generate after protocol processes are derived from the snpinvown of nc0 feeds back nc0 by ni interface, and then nc0 is anti-to ha
Present rspi, then ha feeds back, to cpu1, the operation that datac_e_cmp(terminates certain address reading data to cpu0 for the cpu1,
But it is not implemented this operation).
Post-process the wbidata being derived from cpu0 because nc1 is first processed from the snpinvown of nc0, complete to snpinvown
The message generating after becoming protocol processes is snpinvown, and the message that wbidata is completed with generate after protocol processes is cmp；Due to
Nc2 first processes and post-processes, from the wbidata of cpu0, the snpinvown being derived from nc0, and snpinvown is completed after protocol processes
The message generating is rspi, and the message that wbidata is completed with generate after protocol processes is wbidata.Thus lead to cpu1 to
The operation failure of certain address reading data of cpu0 or cpu0 write the operation failure of data to ha.
Thus, when existing in the many parts of messages that receiving unit 31 receives, read/write operation is carried out to same operation address
During at least two parts of messages, output unit 34 may export different described feedback messages, leads to server None- identified, also no
Method realizes multiple in same server for realizing between the 2nd nc of protocol processes mutually backing up.
For this reason, in order to ensure that output unit 34 only exports a described feedback message, and in order to avoid need to access with
One operation address is assigned to the 2nd nc with the simultaneously allocated unit of multiple messages 32 completing protocol processes, and Fig. 4 shows this reality
The composition structure of another message generating means of example offer is provided, for the ease of description, illustrate only related to the embodiment of the present invention
Part.
As one embodiment of the invention, described message generating means also include:
Address list unit 41, for preserving the operation address of described message, described operation address is that described message is entered
The required address accessing of row protocol processes；
Judging unit 42, if be not stored with described in described receiving unit 31 receives for described address list unit 41
The operation address of message, then carry out mirror image to send at least two the 2nd nc by described allocation unit 32 by described message, and
The operation address of the described message receiving described in preserving in described address list unit 41.
Preferably, described operation address, particularly as follows: described in described message, carry out needing during protocol processes accessing
Memory address.
It should be noted that distributing to the 2nd nc described at least two to carry out the institute of protocol processes for allocation unit 32
There is described message, before each described 2nd nc all feeds back described feedback message, described address list unit 41 is deposited always
Contain the corresponding operation address of described message；That is, after all of described 2nd nc has fed back described feedback message, just meeting
Address list unit 41 is deleted described feedback message is corresponding do not carry out protocol processes before described message operation address.
So, the described message just having received for receiving unit 31, extracts the behaviour of described message from described message
Make address；If judging unit 42 travels through after searching in address list unit 41, the described message not finding and receiving
Operation address identical operation address, then add the operation address of the described message receiving in address list unit 41；With
This executes allocation unit 32 to allow multiple described 2nd nc carry out protocol processes to described message simultaneously simultaneously.
Preferably, meanwhile, described message generating means also include:
Described wait unit 43, for adding the described message that described receiving unit 31 receives in waiting list；
Described judging unit 42, is additionally operable to:
The operation address of the described message that described receiving unit 31 receives if described address list unit 41 has been stored with,
Then the described message that described receiving unit receives is added in waiting list by described wait unit 43.
It should be noted that treating the operation address of the described message in described waiting list in described address list unit 41
During middle deletion, then execution allocation unit 32 is so that described 2nd nc carries out protocol processes to described message.
So, in described address list unit 41, there is phase for the corresponding operation address of described message just having received
With the situation of record, judging unit 42 jumps to wait unit 43 and executes, and the described message receiving is added into wait simultaneously
In queue.
Preferably, when described message is distributed to multiple 2nd nc and carried out protocol processes by allocation unit 32, in order to protect
The described feedback message demonstrate,proving each described 2nd nc feedback is all the same, and described allocation unit 32 is additionally operable to:
Specify each described 2nd nc to be used for executing the resource of protocol processes, record the corresponding resource number of described resource.
It should be noted that the described resource for executing protocol processes includes the operation address of needs access, storage money
Source, cache resources etc. are used for executing required software and hardware resources in agreement process.The described money of record in allocation unit 32
Source number, executes required resource during protocol processes for identifying described 2nd nc.
So, after described allocation unit 32 complete described resource specify after, each described 2nd nc is used for executing agreement
The resource (being especially carried out needing the operation address accessing in agreement process) processing is the same, thus generate is described
Feedback message is also the same.
Preferably, because the described feedback message that the 2nd nc each described produces is the same, described message generates dress
Put and also include:
Filter element 44, if receive described feedback message for described message feedback unit 33 first time, by described
Output unit 34 exports described feedback message, and records the described message characteristic value feeding back message, deletes described resource number.
It should be noted that the described feedback report that same described message generates after described 2nd nc carries out protocol processes
Stationery has same message characteristic value；And, described message characteristic value is documented in described feedback message.
So, for same described message although above-mentioned all of described 2nd nc feedback described feedback message extremely
The arrival time of message feedback unit 33 is different, but, output unit 34 only sends described message feedback unit 33 at first
The described feedback message that secondary (for the first time) receives；Simultaneously, filter element 44 records the described feedback once reaching at first
The message characteristic value of message, in order to filter out described message that receive below, same through described in protocol processes generation
Feedback message.
Preferably, described filter element 44, is additionally operable to:
If described message feedback unit 33 receives described feedback message for the last time, delete the report of described feedback message
Civilian characteristic value, deletes the message before executing protocol processes and generating described feedback message from described address list unit 41
Operation address.
So, for all described 2nd nc that same described message is carried out with protocol processes, message feedback unit 33 is all
Have received the feedback message of each described 2nd nc feedback, thus deleting the message characteristic value of described feedback message；Meanwhile,
The operation address of the message before the corresponding protocol processes in execution of described feedback message is deleted in described address list unit 41.
Meanwhile, need same operation address to complete the report of protocol conversion with described message when existing in waiting list
Wen Shi, allocation unit 32 carries out sending multiple second after mirror image by this waiting list, using the message of same operation address
Nc is to execute protocol processes；Thus, efficiently avoid the 2nd nc and agreement is carried out to the multiple messages using same address simultaneously
Process it is ensured that the feedback message that same message generates after carrying out protocol processes is the same.
As one embodiment of the invention, through Preset Time, delete the message characteristic value of described feedback message, from described
Delete in execution protocol processes and generate the operation address of the message before described feedback message in location list cell 41.
Do not feed back described in time to message feedback unit 33 in order to avoid certain is used for the 2nd nc error of protocol processes
Feedback message, presets described Preset Time.The another object presetting described Preset Time is: through described default
Then it represents that the protocol processes of this message terminate after time, in order to avoid impact waiting list in using with described message
Need the message of same operation address, allocation unit 32 is in time by message in this waiting list, using same operation address
Multiple 2nd nc are sent to execute protocol processes after carrying out mirror image.
