As fully visible, cluster typesetting system of the present invention can be given full play to the processing power of a plurality of type-setting modules, can automatically the waiting typesetting request be distributed to idle type-setting module, the a plurality of composing requests of parallel processing have been realized, improved the handling capacity of composing system to the request of setting type, and when certain type-setting module aborted, the type-setting module that is in idle condition to current is redistributed in the composing operation that this type-setting module can carried out, thereby has increased the robustness of composing system operation.
Accordingly, the present invention also provides a kind of cluster typesetting method, sees also Fig. 2, and this figure is the process flow diagram of cluster typesetting method of the present invention, and it mainly comprises step:
Step S20, external client are initiated authentication request to the interface module of composing system, if authentication is passed through, then interface module allows external client to initiate the request of setting type.
Step S21, external client send the request of composing to interface module, and interface module is carried out encoding process to the composing request that receives, and are converted into the inner identifiable information form of composing system, pass to scheduler module.
Step S22, scheduler module are judged the type of the composing request that receives, and carry out corresponding the processing according to the type of the composing request that receives;
Recording the information of two aspects in the described scheduler module, is the parameters of relevant type-setting module on the one hand, comprises sign, job state and the current Processing tasks sign of each type-setting module; Be relevant composing operation implementation status on the other hand, comprise composing the job list of wait to set type the job list and current execution, having of these two tabulations be beneficial to distribution and the management of scheduler module to the composing operation.
The composing request that receives when scheduler module is when inquiring about the request of type-setting module job state, execution in step S23, S24; When the composing request that receives when scheduler module is the composing job request, execution in step S25.
Step S23, scheduler module feed back to interface module with the job state of each type-setting module of self record.
Step S24, interface module carry out decoding processing to the job status information of each type-setting module of receiving, be converted into external client identifiable information form after, feed back to external client, flow process finishes.
The job list to be set type of step S25, scheduler module inquiry self record judges whether to exist still unenforced composing operation, if there is execution in step S27; Otherwise, execution in step S26.
Step S26, scheduler module are inquired about the job state of each type-setting module, judge that wherein whether having operation is idle type-setting module, if there is execution in step S28; Otherwise, execution in step S27.
Step S27, scheduler module are charged to the composing operation of this new reception in the job list of waiting to set type;
Scheduler module is periodic judges in the job list of waiting to set type whether have operation to be set type, if exist, then the schedule job state is carried out this operation to be set type for idle type-setting module, see also Fig. 3, this figure is that scheduler module is carried out the set type process flow diagram of operation of waiting in the job list of waiting to set type, and its specific implementation process is as follows:
Steps A, scheduler module judge in the job list of waiting to set type whether have operation to be set type, if, execution in step B, otherwise flow process finishes;
It is idle type-setting module that step B, scheduler module judge whether to exist job state, if exist, and execution in step C, otherwise flow process finishes;
Step C, scheduler module obtain the most forward operation to be set type from the job list of waiting to set type, set type for any one job state that inquires for idle type-setting module this job assignment of waiting to set type, and this operation of waiting to set type deleted from the job list of waiting to set type, and add in composing the job list of carrying out;
Step D, type-setting module feed back the execution result of this composing operation after executing the composing operation of described distribution to scheduler module;
After step e, scheduler module are received the execution result of this composing operation, this composing operation is deleted from composing the job list of carrying out, and this result is fed back to interface module, the composing operation execution result that interface module will receive carries out decoding processing, after being converted into external client identifiable information form, feed back to external client, return steps A.
Step S28, scheduler module are with the composing job assignment of this new reception type-setting module to any one free time that inquires.
Step S29, type-setting module are carried out corresponding composing operation according to the composing job request that receives, and after the composing operation is finished, composing operation execution result are fed back to interface module by scheduler module.
The composing operation execution result that step S30, interface module will receive carries out decoding processing, be converted into external client identifiable information form after, feed back to external client.
For avoiding because the aborted of type-setting module causes losing of the composing operation carried out, in above-mentioned cluster typesetting process, each type-setting module of composing operation is being carried out in the periodic monitoring of described scheduler module, when type-setting module generation aborted, it is the type-setting module that free time and processing power satisfy this job requirements that the composing operation that this type-setting module is being carried out is redistributed to other job states.
For maintenance interface module and scheduler module, and being connected between scheduler module and the type-setting module, in above-mentioned cluster typesetting process, described interface module periodically sends connectivity verification message to scheduler module, if scheduler module is received this checking message, then reply corresponding connectivity verification response to interface module; Described scheduler module periodically sends connectivity verification message to each type-setting module, if type-setting module is received this checking message, then replys corresponding connectivity verification response to scheduler module.Described type-setting module find self with scheduler module between be connected when disconnecting, send connection request from the trend scheduler module connection that disconnects repaired; Described scheduler module find self with interface module between be connected when disconnecting, send connection request from the trend interface module connection that disconnects repaired.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
