Description
Technical field
The present invention is a kind of about the sequential distribution structure in the computer system, particularly in the standby sequential distribution structure of the blade point type cluster system of tool symmetric multiprocessor performance.
Background technology
For now, the essence difference of symmetric multiprocessor system (SMP system) and blade point type cluster system (bladeclustering system) remains and is difficult to be broken.These two systems design with running under certain configuration at some purpose.The system of two patterns is combined into one, it will be one of main problem that sequential is distributed.
Generally speaking, reliable and the symmetric multiprocessor system of high-order has a standby sequential distribution system, and typical blade point type system has special-purpose regional timing sequence generating and distribution system on each knife edge.
Fig. 1 is for having the example of the high order symmetry formula multicomputer system of sequential distribution in the routine techniques.Have several computing modules 120,130,140 ... system to comprise the first central sequential device 111 and the second central sequential device 112 be two identical sequential sources, its exchange sequential marginal correction information (clock edgealignment information) is to keep same sequential marginal correction.Two or more computing module (compute module) 120,130,140 ... (system bus) is connected to each other with system bus, and the one or more symmetric multiprocessors of activation field, each of computing module 120,130,140 receives two reproducing signals of sequential signal in the first central sequential device 111 and second central sequential device 112 generations and distribution.Multiplexer 121/131/141 is used to switch this two central sequential, if one of them is malfunctioning for the first central sequential or the second central sequential, then must use another.Therefore a typical symmetric multiprocessor system common (synchronized) synchronously or sequential marginal correction are so that the total system running.In addition, regional sequential device 122/132/142 may just be used for test.Because regional sequential device 122/132/142 is not through synchronous or sequential marginal correction, under normal operation, regional sequential device 122/132/142 generally is anergy (disabled) or suspends (suspended).Therefore, no matter regional sequential device all is a kind of waste on the space of substrate or on the performance of the symmetric multiprocessor system in the running.
Fig. 2 is the exemplary embodiments of blade point type cluster system 150 in the routine techniques, because each knife edge 151,152,153 ... it all is the stand-alone computer of a running different operating system, therefore do not need through synchronous or sequential marginal correction, if arbitrary knife edge 151,152,153 ... regional sequential device malfunctioning, other knife edge will continue the running.As long as the arrangement that the management system of gathering together (clustering management system) can Processing tasks/send, knife edge system still can be used in new task.Therefore, the most of knife edge system of routine techniques does not have standby sequential device (redundant clock (s)).But then, mean that also conventional knife edge system does not have the performance of symmetric multiprocessor in the knife edge, because it lacks synchronously or the sequential marginal correction.
For realizing flexible system configuration, make knife edge system have the performance of symmetric multiprocessor, at first the structure of timing sequence generating and distribution must be rearranged.
Summary of the invention
Therefore, the invention provides standby sequential distribution structure makes the blade point type cluster system have the performance of symmetric multiprocessor.The present invention uses a central sequential device and some spare area sequential devices, and provides the blade point type cluster system large-scale symmetric multiprocessor performance.
At embodiments of the invention, the blade point type cluster system with symmetric multiprocessor performance comprises a some knife edge modules and a sequential distribution structure.Each knife edge module comprises several regions sequential user.The sequential distribution structure comprises a sequential multiplexer (clock multiplexer), is arranged at a regional sequential device that can operate and a central sequential device on each knife edge module.Central authorities' sequential device is in order to produce central clock signal, the regional clock signal that the sequential multiplexer receives central clock signal and produced by regional sequential device, central clock signal is selected and is sent to the regional sequential user of each knife edge module by the sequential multiplexer; If wherein central sequential device is malfunctioning, be positioned on the knife edge module in the preface multiplexer switch central clock signal, change the sending zone clock signal into to regional sequential user.

Embodiment
The invention provides a standby sequential organization, make blade point type cluster system equipment have the feature of high order symmetry formula multiprocessor, and make its rubber-like system architecture.
See also Fig. 3, a blade point type cluster system mainly comprises a central sequential device 10 and some knife edge modules 20,30,40,50.The blade point type cluster system comprises necessary computer hardware and substantially and gathers together the management system (not shown) to manage the running of knife edge module 20,30,40,50.(for more clearly explanation is provided, other component of a system that the blade point type cluster system is comprised is omitted in graphic.) this management system of gathering together is a software program, between knife edge module 20,30,40,50 and user as management/running interface.In the present invention, the management system of the gathering together support calculating (cluster computing) of gathering together comprises that the asymmetric that has/do not have host node (head node) is gathered together (asymmetric clustering) and symmetrical expression is gathered together (symmetric clustering).
Each knife edge module 20/30/40/50 can be treated as a stand-alone computer, realizes on a motherboard usually.Knife edge module 20/30/40/50 and different electronic component be for example: the I/O connector of processor, Installed System Memory, bridge-type chip, i/o controller, network interface controller, expansion board (all showing), a sequential multiplexer (MUX) 21/31/41/51 and regional sequential device 22/32/42/52 are embodied in printed circuit board (PCB).These elements connect each other to carry out the task of data processing via specific bus.The operating system that each knife edge module 20/30/40/50 has a special use is provided with hardware element on it to carry out direct monitoring and management, manages various computer resources and the environment of an operation of application software is provided.In the present invention, the operating system of each knife edge module-specific has the performance of carrying out the symmetric multiprocessor configuration.
The processor (not shown) of knife edge module 20,30,40,50 is the one chip processors that are installed in application specific processor slot (not shown), and each is provided with one or more calculating cores (computing core).According to the present invention, all processors in the blade point type cluster system can be supported the configuration of various symmetric multiprocessors, for example: 1,2,4 or 8 process chip etc.That is, in the blade point type cluster system, not only symmetric multiprocessor zone may existingly be arranged.
It is outer or be arranged at the central sequential device 10 of one of knife edge module 20,30,40,50 to be arranged at circuit board, produces and distributes a synchronous central clock signal to give each knife edge module 20,30,40,50.At some specific example, this central authorities' clock signal can be provided by the regional clock signal device of one of knife edge module 20,30,40,50.Central authorities' sequential device 10 is controlled by the management system of gathering together, with the execution task of gathering together.
Be arranged at regional sequential device 22/32/42/52 on each knife edge module 20/30/40/50 and be a sequential source independently, when the blade point type cluster system was operating, regional sequential device 22/32/42/52 produced and also distributes a regional clock signal that can operate.Zone sequential device 22/32/42/52 also can be used for independent running, for example: test, debug, problem reparation, if regional sequential device 22/32/42/52 can be kept identical sequential marginal correction, just the blade point type cluster system can operate the feature (with reference to Fig. 4) that (single blade operation) supports complete sequential failover capability by the single knife edge.
Sequential multiplexer 21/31/41/51 is electrically connected central sequential device 10 and at the regional sequential device 22/32/42/52 and regional sequential user of each knife edge module 20/30/40/50.Central authorities' clock signal and regional clock signal are sent to sequential multiplexer 21/31/41/51.
The state of sequential multiplexer 21/31/41/51 monitoring clock signal can be by selecting a sound clock signal in central clock signal and the regional clock signal.Sequential multiplexer 21/31/41/51 is predeterminable for selecting central clock signal, if selected central clock signal has problem, and other clock signal perfects, and sequential multiplexer 21/31/41/51 will switch to sound signal by the signal source of fault.The concrete instance of sequential multiplexer 21/31/41/51 is to select phase-locked loop (PLL), and this is controlled by the management system of gathering together.The state of the management system monitoring sequential of gathering together of blade point type cluster system, the path that control timing is distributed, and take necessary action to recover this blade point type cluster system.
Please refer to Fig. 4, in the pattern (single-blade operation mode) of single knife edge running, have only a knife edge module 20/30/40/50 and each operating system 02/03/04/05 field to contain.Under this pattern, the generation of sequential is standby with distributing fully.
As same cluster system, the blade point type cluster system is predeterminable for using central clock signal.In case central sequential device 10 is malfunctioning or problem arranged, sequential multiplexer 21/31/41/51 switches and regional clock signal that this knife edge module 20/30/40/50 of blade point type cluster system can use its regional sequential device 22/32/42/52 to be produced, so the running that is still kept knife edge module 20/30/40/50.If regional sequential device 22/32/42/52 can the retaining zone clock signal and the sequential marginal correction of central clock signal signal when central authorities before malfunctioning, whole blade point type cluster system can keep the synchronous running of gathering together.Relative, if no synchronization zone clock signal, each knife edge module 20/30/40/50 will still can operate, as long as the arrangement of the lasting Processing tasks of management system of gathering together/to send, the blade point type cluster system still can be used for new task.
Please refer to Fig. 5, in multitool cutting edge of a knife or a sword operating mode (multiple-blade operation mode), the processor of two knife edge modules (20,30)/(40,50) is connected to form two or more symmetric multiprocessors/ operating system field 06,07 by two system buss.One network connections (network connection) connects this symmetric multiprocessor/ operating system field 06,07 with gathering together, and this is configured in the scope in same symmetric multiprocessor/ operating system field 06,07 needs synchronous sequence.In an embodiment, in case it is should central authorities' sequential device 10 malfunctioning, because regional sequential device (22,32)/(42,52) can't provide the processor synchronous sequence signal that is arranged in same symmetric multiprocessor/operating system field, the task of well afoot will can not replied.System bus can be realized that for example: these a little bus compatibles are in the HyperTransport agreement to allow the symmetrical expression multiprocessing by the circuit between two or more processors of any connection in the present invention.Network connections comprises actual high-speed interface and is connected between the network interface controller of knife edge module, for example: unlimited broadband links (infinite Band connection) or the GB Ethernet links (GigabyteEthernet connection).
A settling mode is to utilize a synchronous module (not shown) with regional sequential device (22,32)/(42,52) of synchronization in same symmetric multiprocessor/operating system field 06/07.
Another settling mode is that to restart the blade point type cluster system be single knife edge operating mode.The management system of gathering together will be utilized its power supply (recycle the power) again, change symmetric multiprocessor configuration and sequential source, and with single knife edge operating mode restarting systems.So knife edge cluster system does not need through any repairing or replaces and will still can be utilized.In routine techniques, replacement or repairing hardware configuration are very time-consuming.Utilize the sequential distribution structure, the invention provides the chance during the blade point type cluster system is kept one section continuation of running.
Central authorities' sequential device is predeterminable to be complete standby mode (full-redundant mode).If can't operate under single knife edge operating mode based on certain reason blade point type cluster system, the management system of then gathering together will need to utilize its power supply again, change this sequential source and restarting systems again, as single knife edge operating mode.
Be used as those knifes edge of central sequential at the outside sequential of needs source, will be dependent on an extra sequential source at those knifes edge of test.The invention provides the elastification of independent computer testing, debug and problem reparation, therefore the knife edge can operate as stand-alone computer.
Necessary computer hardware and/or software/firmware configuration may need to be used to change the configuration of symmetric multiprocessor.The present invention's standby sequential distribution structure is one of pacing items for the elastification system configuration.
Though technology contents of the present invention discloses as above with preferred embodiment, so it is not in order to limiting the present invention, anyly has the knack of this skill person, does a little change and retouching in the spirit that does not break away from the present invention, all should be covered by in the present invention's the category.
