Before illustrating that the physical location of the logic CPU disclosed by the present invention judges system and method thereof, first the noun of institute of the present invention self-defining is explained, physical cpu of the present invention refers to the CPU (central processing unit) (CENTRALPROCESSINGUNIT of physics, CPU), it processes the related data of application program in order to computer instructions; Core (Core) and hyperthread (Hyper-Threading) is then comprised as logic CPU.For example, suppose there are two physical cpus, each physical cpu has four cores, and has Hyper-Threading, then the quantity of logic CPU is 16 (2*4*2=16).
The graphic physical location to logic CPU of the present invention is below coordinated to judge that system and method thereof are described further, please first consult Fig. 1, Fig. 1 is the system block diagrams that the physical location of logic CPU of the present invention judges system, and this system comprises: radiating module 110, sensing module 120, compression module 130 and judge module 140.Wherein, the radiating condition that radiating module 110 remains identical in order to make multiple physical cpu, wherein each physical cpu has multiple logic CPU.On reality is implemented, it is consistent that the mode making physical cpu maintain identical radiating condition comprises the rotation speed of the fan controlling respective physical CPU, such as: the rotating speed controlling all cpu fans is 5400rpm.In addition, because physical cpu and logic CPU explain in aforementioned self-defining noun, therefore much more no longer to repeat at this.
Sensing module 120 is in order to the surface temperature of lasting each physical cpu of sensing.On reality is implemented, high precision paster thermometer, thermistor or temperature sensor can be selected to sense the surface temperature of physical cpu at the slot position of physical cpu.Be noted that the present invention is not limited with the assembly of above-mentioned sensing temperature especially, as long as the assembly (as: infrared thermometry device, thermal imaging system etc.) that can be used in the surface temperature sensing physical cpu neither departs from range of application of the present invention.
Compression module 130 is in order to pressurize to each logic CPU and to reduce pressure respectively, and wherein said being pressurised into increases CPU floating-point operation amount in the unit interval to improve power consumption, and described decompression is for the described logic CPU that leaves unused is to reduce power consumption.For example, following computer instruction can be used when pressurizeing:

addpsxmm3,xmm4
Above computer instruction effectively can promote the power consumption of physical cpu, and then makes cpu temperature increase fast, such as, at about one second, cpu temperature is promoted to 100° centigrade (100 DEG C) left and right by normal temperature; Multiple dummy instruction (as: nop) then can be used continuously to realize idle logic CPU to reduce power consumption when reducing pressure.On reality is implemented, compression module 130 continuous pressurization, until the surface temperature of physical cpu reduces pressure after reaching preset temperature (such as: 90 degree Celsius) again, avoids excessively pressurization to cause logic CPU to damage.In addition, keep constant to make the surface temperature of physical cpu, on reality is implemented, the instruction of CPU floating-point operation can also be adjusted, such as, use circular constant computing method with the surface temperature of constant CPU, or in the instruction of CPU floating-point operation, increase dummy instruction to reduce the quantity of floating-point operation in the unit interval and then increase surge time and reduce power consumption pulling speed, or the quantity of adjustment single precision floating datum operational order (as: mulps, addps).Be noted that the usage due to the above-mentioned CPU floating-point operation instruction mentioned is all prior art especially, therefore much more no longer repeat at this.
Judge module 140 in order to according to each logic CPU in pressurize and decompression time, the physical cpu that sensing module 120 senses surface temperature change, the physical cpu that decision logic CPU is corresponding and slot thereof are to show.On reality is implemented, during due to compression module 130 pairs of logic CPU pressurizations, the surface temperature of its corresponding physical cpu can significantly promote, so the surface temperature change of judge module 140 physical cpu that can sense according to sensing module 120 comes decision logic CPU which physical cpu corresponding and slot thereof.For example, suppose there are two physical cpus, it lays respectively at slot Socket0 and Socket1, when to first logic CPU pressurization, judge module 140 learns that the surface temperature of the physical cpu being positioned at slot Socket1 significantly rises, and now can judge that the physical cpu of first its correspondence of logic CPU is positioned at slot Socket1.Thus, suppose that described first logic CPU notes abnormalities in other tests, user because know that the physical cpu that this logic CPU is corresponding is positioned at slot Socket1, therefore, can directly replace be positioned at slot Socket1 physical cpu to get rid of this unusual condition.
Then, refer to Fig. 2, Fig. 2 is the physical location determination methods of logic CPU of the present invention, and its step comprises: make the radiating condition that multiple physical cpu remains identical, and wherein each physical cpu has multiple logic CPU (step 210); Continue the surface temperature (step 220) of each physical cpu of sensing; Pressurize to each logic CPU and reduce pressure respectively, wherein said being pressurised into increases CPU floating-point operation amount in the unit interval to improve power consumption, and described decompression is for the described logic CPU that leaves unused is to reduce power consumption (step 230); According to each logic CPU in time pressurizeing and reduce pressure, continue the surface temperature change of the described physical cpu sensed, judge that the described physical cpu that described logic CPU is corresponding and slot thereof are to carry out showing (step 240).Through above-mentioned steps, namely can pass through the surface temperature continuing each physical cpu of sensing, and by the CPU floating-point operation amount increased logic CPU in the unit interval to improve power consumption, significantly to promote the surface temperature of corresponding physical cpu, and then determine the physical cpu corresponding with logic CPU.
