For computer system, (stable power source is one of top-priority emphasis for high performancecomputing, HPC) field person particularly to be applied to HPC.At present, electric power is provided and does not interrupt for constant, supercomputer with hundreds of nodes (node) uses large-scale UPS usually, and (uninterrupted power system is UPS) as the electric power back-up system of external communication to interchange (AC to AC).But, Wai Bu UPS also can't solve the power supply supply problem of any inside computer system.
Except the external power back-up system, (redundant power system RPS) also can keep computer system and not interrupt running internal communication to the redundant electric system of direct current (AC to DC).RPS possesses two specific characters usually, is respectively: include at least two group power supply units (power supplier) and support hot plug (hot-swap).So, can allow use in arbitrary power supply unit fault or when extracting any power supply unit out, but still normal operation of system.The characteristics of RPS are that each group power supply unit all is provided by all electric power that can independently provide system required, so its volume is higher with supply power, also costliness comparatively of price.
Yet, gathering together for the computing machine (low-nodes cluster computer) for low node, inner RPS is not suitable fully.Please refer to the individual supercomputer (personalsupercomputer) shown in Fig. 1 prior art, with individualized computing is demand, be applied to small-sized scientific domains such as model analysis, research emulation, it is equipped with five mainboards, as computing node 82 (compute nodes), first power supply unit 70 and second source supply 72 see through power distribution circuit 90 and give a host node 80 and four computing nodes 82 with distributing electric power as host node 80 (head node), all the other four for one of them.Because individual supercomputer is usefulness guiding (performance-oriented), density guiding (density-oriented) and cost-oriented (cost-oriented), if first power supply unit 70 and second source supply 72 design with the RPS framework in the power module, can produce the problem of spatial configuration and cost; But, then can meet with the problem of fiduciary level deficiency if do not adopt the framework of RPS.
For example: first power supply unit 70 and second source supply 72 respectively can provide 850W electric power, each computing node 82 to need 280W electric power, host node 80 to need 450W electric power, when first power supply unit, 70 faults, total system promptly can lose 850W electric power moment, and each node only is assigned to the electric power of about 170W, causes undesired shutdown, data damage, work not to have problems such as early warning interruption far below its required electric power of running; At this moment, even outside UPS can normally provide alternating current, still can't provide the standby power supply of direct current.
Hence one can see that, and there is conflicting problem between spatial configuration, cost and fiduciary level three in the power supply unit of the computing machine of gathering together.Therefore, the framework of improved power provider system how, make its can be less with volume, output power and the power supply of lower-cost power supply unit, guarantee computing machine unlikely problems such as data loss, undesired shutdown that cause under the burst powering-off state simultaneously, be a problem to be improved.

Embodiment
Please refer to first embodiment of Fig. 2 for electric power switching mechanism of crowd together computer.
The computing machine 08 of gathering together is made up of host node 80 and four computing nodes 82, host node 80 can be to build with each computing node 82 and places five uniprocessor or multicomputer systems on the independent mainboard, and by four computing nodes 82 of host node 80 management, with the work scheduling of the computing of gathering together.The electric power of computing machine 08 of gathering together is provided by first power supply unit 70 and second source supply 72, and carries out voltage transitions, distributing electric power by power transfer device 01, and the switching of power supply mechanism.
Under the normal condition, first power supply unit 70 must make a concerted effort to power with second source supply 72 in the present embodiment, the host node 80 of load simultaneously and all computing nodes 82; That is any one all can't independently-poweredly give the whole computing machine 08 of gathering together first power supply unit 70 and second source supply 72.
Power supply input circuit 10 electrically connects first power supply unit 70, second source supply 72, gate circuit 40 and handover module 50.With regard to distributing electric power, input electric power P1, P2 that power supply input circuit 10 receptions, first power supply unit 70 and second source supply 72 are provided, and be sent to handover module 50; And about with input electric power P1, status signal S1 (as PSON1 L), S2 (as PSON2 L) that P2 is corresponding, then be sent to gate circuit 40 respectively.
Wherein, first output circuit 20 electrically connects handover module 50, host node 80 and each computing node 82, can export input electric power P1, P2 to host node 80 and each computing node 82 simultaneously, second output circuit 30 then electrically connects handover module 50, host node 80 and standby power module 60, exports host node 80 to the standby power Ps that will import electric power P1, P2 residue person or standby power module 60.
Be positioned at the switch 55 of 60 of first output circuit 20 and standby power modules, can be used to limit direction of current; It can be by MOS switch or diode switch specific implementation.As long as the layout strategy of power supply supply is only to supply power to host node 80 when occurring interrupting at input electric power P1, P2, switch 55 can allow standby power module 60 be charged by first output circuit 20, but prevents between transfer period first output circuit 20 and four computing modules 82 discharges.So, standby power module 60 only needs less output power to get final product.Can promptly do not need switch 55, but the output power of standby power module 60 be with the summation of convergence two power supply units 70,72 to first output circuit 20 and four computing module 82 discharges if desire to make standby power module 60.
As input electric power P1, when P2 is power supply state (power-on state), pairing status signal S1, S2 just are in a specific supply voltage level, for example PSON1 L (S1), PSON2 L (S2) the two be positioned at low level, the switching signal Sw that gate circuit 40w is produced, control handover module 50 is kept the electric connection with first output circuit 20.And when input electric power P1, P2 wherein one or the two is when being interruption status (power-off state), pairing status signal S1, S2 just are in a specific outage voltage level (for example PSON1_L, PSON2_L the two be positioned at high level), the switching signal Sw that gate circuit 40w is produced, control handover module 50 switch to second output circuit 30 and electrically connect.For reaching above-mentioned switching controls, gate circuit 40 can be the AND logic gate, and handover module 50 can be relay (RELAY).
The disclosed power transfer device 01 of present embodiment, all indicate input electric power P1 at status signal S1, S2, when P2 is power supply state, handover module 50 can keep being electrically connected to first output circuit 20 with power supply input circuit 10, at this moment, just electric power P1, P2 be will import and host node 80 and each computing node 82 all exported to by first output circuit 20; Simultaneously, standby power module 60 is also via the first output circuit 20 charging electric power that stores for future use.
When status signal S1, S2 indication is imported electric power P1, P2 one or is all fault, handover module 50 can be electrically connected to second output circuit 30 with power supply input circuit 10, can't independently satisfy all electricity needs of host node 80 and computing node 82 this moment owing to input electric power P1 that does not interrupt or P2, therefore handover module 50 is electrically connected to second output circuit 30 with power supply input circuit 10, with the input electric power P1 or the P2 of fault do not export host node 80 to by second output circuit 30.
Generally speaking, because handover module 50 needs several milliseconds time to switch, therefore between transfer period, first output circuit 20 can be because be connected with power supply input circuit 10 with second output circuit 30, and have several milliseconds to be in no power supply state, and the power supply situation at the initial stage of switching is unstable, promptly provide stored standby power Ps by standby power module 60 this moment, export host node 80 to by second output circuit 30, to keep the normal power supply of host node 80, host node 80 could be handled the work interruption content of each computing node 82 in real time, and stores the duty at last passed and the data of each computing node 82 before outage.Therefore, standby power module of the present invention 60 is essential can be between a given period in, the electric power that independently supplying host node 80 is required.
In addition, in the selection of power supply unit, the output power sum of above-mentioned first power supply unit 70 and second source supply 72 equals host node 80 and all computing nodes 82 required operating power summations and adds a safety value.
Illustrate, as shown in Figure 2, host node 80 needs 450W electric power, four computing nodes 82 respectively need 280W electric power, total system needs 1570W electric power altogether, adopt the present invention gather together computing machine 08 power transfer device 01, the first power supply unit 70 and second source supply 72 each approximately only need provide 850W electric power get final product, the safety value existence of 130W is also just arranged.So just can keep the fiduciary level of total system power supply, if unlike the technology that adopts previous redundant electric system, power supply unit is all wanted for 70 every groups 1570W electric power can be provided, and not only produces the expensive problem configuration space that also generation need be bigger simultaneously.
Please refer to second embodiment of Fig. 3 for electric power switching mechanism of crowd together computer.In fact, all nodes of the computing machine of gathering together all need several different voltages, to meet the operating voltage of various assemblies on the mainboard; So, will the derive voltage differences and the DC-to-dc dividing potential drop problem of standby power module.
To this, the main difference place of present embodiment and last embodiment, the power transfer device 01 that is present embodiment comprises that more dc voltage divider circuit 14, first distributor circuit 22 and second distributor circuit 32 will import that electric power P1, P2 are divided into three kinds of voltage V1, V2, V3 gives each node, and, carry out circuit switching controls and the standby power supply of different voltage V1, V2, V3 respectively with 51,52,53 and three standby power modules 61,62,63 of three handover modules.
Power supply input circuit 10 is except that connecting gate circuit 40, first power supply unit 70 and second source supply 72, and more circuit connects three handover modules 51,52,53.Power supply input circuit 10 comprises input linkage unit 12,13 and dc voltage divider circuit 14.
Dc voltage divider circuit 14 is electrically connected at input linkage unit 12, be used for dividing potential drop input electric power for the needed different voltage V1 of each node, V2, V3 (as 3.3V, 5V, 12V) after, be sent to handover module 51,52,53.For haveing the knack of this skill person, dc voltage divider circuit 14 also can be integrated in first power supply unit 70 and the second source supply 72, and only needing provide power connector to get final product at different voltages, is not power transfer device 01 imperative person.
The first output linkage unit 241,242,243 comprises the power connector of different voltages, electrically connects first distributor circuit 22, host node 80 and four computing nodes 82, exports host node 80 and all computing nodes 82 to will import electric power.
The second output linkage unit 341,342,343 comprises the power connector of different voltages, electrically connects second distributor circuit 32 and host node 80, exports remaining input electric power to host node 80.
Power supply mechanism with voltage V1 is an example, input electric power P1 that first power supply unit 70 and second source supply 72 are provided and P2 are the needed different voltage V1 of each node, V2 and V3 part through dc voltage divider circuit 14 dividing potential drops after receiving via input linkage unit 12.When status signal S1, S2 all indicate input electric power P1, when P2 is power supply state, handover module 51 can partly keep the voltage V1 of power supply input circuit 10 to be electrically connected to the voltage V1 part of first output circuit 20, input electric power after the dividing potential drop is transmitted through handover module 51, first distributor circuit 22, the input electric power of voltage V1 is sent to the first output linkage unit 241, arrive host node 80 and four computing nodes 82 at last, standby power module 61 is the charging electric power that stores for future use at this moment also.
When status signal S1, S2 wherein each or the two all indicate input electric power P1, when P2 is interruption status (Power-off state), handover module 51 can partly be electrically connected to second output circuit 30 with the voltage V1 of power supply input circuit 10, this moment is owing to there is input power breakdown partly, the input electric power of Zhong Duaning can't not satisfy the electricity needs of all voltage V1 parts of host node 80 and computing node 82, so will be sent to host node 80 through the second output linkage unit 34 for the voltage V1 input electric power that interrupts via second distributor circuit 32.
Between the transfer period of handover module 50, first output circuit 20 there is no with second output circuit 30 because with power supply input circuit 10 and is connected, therefore having several milliseconds is in no power supply state, promptly provide stored standby power Ps1 (voltage V1) by standby power module 61 this moment, by second output circuit 30 to host node 80, to keep the voltage V1 part normal power supply of host node 80.
Can be disposed on the power transfer device practice of the present invention on the power supply switch circuit plate (power switchboard), but the disclosed standby power module of previous embodiment, do not limit and be disposed on this power supply switch circuit plate, the standby power module is under the prerequisite that does not change circuit connecting mode of the present invention, also configurable on host node, or separate configurations is outside host node or power supply switch circuit plate.
In addition, switching signal Sw can be sent to the input and output stitch of the specific controller of host node 80, carries out the signal or the order source of work Interrupt Process as the operating system of the computing machine 08 of gathering together.As for the switch 55 that uses among the 2nd figure, also visual demand disposes between first output circuit 20 and standby power module 60 of Fig. 3.
Please refer to Fig. 4 A and be the power-supply switching method process flow diagram of computing machine of gathering together.According to the power transfer device that previous embodiment discloses, power-supply switching method of the present invention mainly contains about the host node of the computing machine of gathering together and the some computing nodes power supply handover mechanism when the arbitrary power supply unit interruption of power supply, and it comprises the following step:
Step 110: receive some input electric power (P1, P2 at the beginning earlier ...) some status signals (S1, the S2 corresponding with it ...).Each status signal be used to refer to the input electric power be power supply state or interruption status, and these the input electric power output power and, equal the required operating power summation of the whole computing machine of gathering together (host node and all computing nodes) and add a safety value; In detail, arbitrary input electric power can't independently be born the electricity needs of the whole computing machine of gathering together.
Step 120: need to confirm according to status signal whether any input electric power is interruption status.All status signals can be in order to judge whether normal power supply of each input electric power, when input electric power is power supply state, its corresponding status signal can be in specific power supply logics level (for example PWRON_L is positioned at low level), still get back to step 110 this moment and continue to receive follow-up input electric power and status signal, have output power also can keep inputing to first output circuit; If when any input electric power was interruption status, its corresponding status signal also can be in specific power-down logic level (for example PWRON_L is positioned at high level), and produce switching signal Sw to carry out the switching of current supply circuit.Between the step 120 and 130, can further comprise the step that produces switching signal according to status signal.
Step 130: after any input power breakdown, remaining input electric power can't be born the electricity needs of the whole computing machine of gathering together, therefore remaining input electric power should be from supplying first output circuit of the whole computing machine of gathering together, switch to second output circuit of only supplying host node; And remaining input electric power promptly switches to second output circuit according to switching signal by first output circuit.
Step 140: because handover module needs to switch to second output circuit by first output circuit between a specific transfer period, promptly needing this moment provides standby power (Sw) to give host node through second output circuit.
Step 150:, can supply remaining output power to host node when handover module switches to second output circuit with remaining input electric power by first output circuit.
In the foregoing description, the computing machine of gathering together is default supply path with first output circuit, therefore be under the power supply state at input electric power, with first output circuit standby power module is charged, supply power to host node and switch when partly or entirely output power interrupts by second output circuit, by the standby power module for power supply, switch back second output circuit and also can charge between transfer period the standby power module.Supplying power to host node under the situation of all computing node interruption of power supply by second output circuit, if the power supply unit that interrupts is through changing, make all output powers reply power supply state, then handover module can supply power to the whole computing machine of gathering together by first output circuit according to the status signal switching; Under the prerequisite of enough electric capacitys, during second output circuit switched back between transfer period of first output circuit, host node still can be by the load of standby power module.
Though technology contents of the present invention discloses as above with preferred embodiment; right its is not in order to limit the present invention; anyly have the knack of this skill person; do not breaking away from spirit of the present invention a little change and the retouching done; all should be covered by in the category of the present invention, so protection scope of the present invention is as the criterion when looking accompanying the claim person of defining.
