What is claimed is:
Aspects of the present invention are directed to a computing system with a compile farm.
Typically, little attention is given to power consumption considerations in software development processing. During the development phase of the software development processing, software testers may have access to data regarding iterative execution of testing frameworks but the data is rarely referred to by the software developers who actually write the software code. Indeed, it is traditional for the software developers to simply write the software code and send code drops to be built and tested by others.
The disconnection between the software developers and the data regarding the iterative execution of testing frameworks frequently leads to problems in the later execution of the software. These problems include, but are not limited to, the likelihood that regressions will exist between the code release date and feedback from performance testing of the code.
In accordance with an aspect of the invention, a computer readable medium is provided and has instructions stored thereon, which, when executed cause a processor of a computing system to execute a method of controlling the computing system, the method including iteratively running a workload over a period of time, the workload being defined by software components of a software repository of the computing system, measuring power consumption associated with the running of the workload with each iteration and storing data indicative of the power consumption, analyzing the data and identifying, from a result of the analysis, power consumption changes over the period of time, generating a regression profile based on the power consumption changes, and managing the software components in accordance with the regression profile.
In accordance with another aspect of the invention, a method of controlling a computing system is provided and includes iteratively running a workload over a period of time, the workload being defined by software components of a software repository of the computing system, measuring power consumption associated with the running of the workload with each iteration and storing data indicative of the power consumption, analyzing the data and identifying, from a result of the analysis, power consumption changes over the period of time, generating a regression profile based on the power consumption changes, and managing the software components in accordance with the regression profile.
In accordance with another aspect of the invention, a computing system is provided and includes a compile farm memory unit, onto which software components of a software repository of the computing system are loadable, a plurality of devices relative to which iterative runs of a workload defined by the software components are executable over a period of time, and a processor, disposed in signal communication with the devices, which is configured to execute the iterative runs and to evaluate power consumption associated with the iterative runs by the devices. The processor includes a computer-readable medium having a set of instructions stored thereon, which, when executed, cause the processor to analyze data indicative of the power consumption, to generate a regression profile based on power consumption changes, and to manage the software components accordingly.
The subject matter regarded as the invention is particularly pointed out and distinctly claimed in the claims at the conclusion of the specification. The foregoing and other aspects, features, and advantages of the invention are apparent from the following detailed description taken in conjunction with the accompanying drawings in which:
With reference to
The processor 30 is disposed in signal communication with the devices and is configured to execute the iterative runs and to evaluate power consumption associated with the iterative runs by the devices. To this end, the processor 30 includes a memory unit 35. The memory unit 35 includes a computer-readable medium having a set of instructions stored thereon, which, when executed, cause the processor 30 to analyze data indicative of the power consumption, to generate a regression profile based on power consumption changes, and to manage the software components accordingly.
As will be described below, the processor 30 may include multiple processing levels arranged in a tree format that includes a top level 31, at which a central processing unit (CPU) may reside, and a bottom level 32, at which one or more disk control units (DCU 1, DCU 2 and DCU 3) reside. Additional processing levels may, of course, be provided between the top and bottom levels 31 and 32. I/O operations are normally instantiated at the top level 31 as the CPU receives and interprets inputted read and write commands. The CPU then assigns components of the iterative runs and/or the I/O operations downstream in accordance with, e.g., read power requirements until they reach each of the various DCUs at the bottom level 32 as components of the iterative runs and atomized I/O operations. Each of the components of the iterative runs and atomized I/O operations is then carried out at a recording medium 20 coupled to an associated one of the DCUs.
The recording media 20 may include removable media that can be removably coupled to the computing system 10 or non-removable media that are normally coupled to the computing system 10. They may also include recording media, such as a universal serial bus (USB) flash drive, an optical disk, a DVD-ROM, etc., from which information is read or onto which information is written in accordance with the executions of the iterative runs and the I/O operations. In any case, each recording medium 20 is provided with a power requirement gauge 50. The power requirement gauge 50 is readable by the processor 30 and provides an indication to the processor 30 as to how much power is required for the iterative runs and/or for an I/O operation to be executed with respect to the recording medium 20.
As shown in
In accordance with an embodiment of the invention and, as shown in
The register 60 for each device is readable by the DCU to which that device is associated. Thus, DCU 1 reads the registers 60 of devices D11, D12 and D13, DCU 2 reads the registers 60 of devices D21, D22 and D23, and so on. Information gleaned from the registers 60 may then be compared with the quantity of power available for I/O operations (this being more important where the computing system 10 is being run with battery power) and is then employed by DCU 1 to schedule the executions of the I/O operations relative to devices D11, D12 and D13 or to refuse the executions of the I/O operations in accordance with the quantity of available power. As will be described below, the information can also be employed in the generation of regression profiles of the software components of the software repository 36.
The information gleaned from the registers 60 of devices D11, D12 and D13 is also aggregated at the DCU 1 register 70 where it can be stored, at least temporarily, in memory unit 80, which is disposed in relative association with the DCU 1. The DCU 1 register 70 includes information reflective of the total power requirement for access incidences of I/O operations for devices D11, D12 and D13 along with information reflective of historical power requirements for devices D11, D12 and D13. The DCU 1 register 70 along with registers for any other DCUs in computing system 10 can be transmitted to higher processing levels, such as top level 31, where additional I/O operation assignments can be made. Where the information is employed in the generation of the regression profiles, the information is transferred to at least a comparator 33 of the processor 30 at the top level 31, where the regression profiles are generated, as will be described below.
With reference to
The processor 160 is coupled to the power source 150 and includes an I/O unit 165, which is disposed in signal communication with the devices. The processor 160 is thereby configured to execute the iterative runs and to evaluate power consumption associated with the iterative runs by the devices by way of the I/O unit 165. To this end, the processor 160 includes a memory unit 170. The memory unit 170 may be a computer-readable medium having a set of instructions stored thereon. When executed, the instructions cause the processor 160 to analyze data indicative of the power consumption, to generate a regression profile based on power consumption changes, and to manage the software components accordingly.
With reference to
As shown in
In accordance with yet another aspect of the invention and, with reference to
The power consumption measurements of operation 610 may be achievable by way of readings of the power requirement gauges 50 of each of the devices. In this way, the power consumption data over the period of time may be entered into the registers 60 for each device and transmitted up through the various processing levels 32 and 31 of the processor 30. The power consumption measurements could also be achieved by system level aggregate power consumption gauges, in addition to, or in the absence of device specific power consumption gauges, such as a kilowatt/hr meter, to measure the total power draw of the system under test conditions. including all components which need to have power consumption measured.
The power consumption data is then analyzed 630 at, e.g., a comparator 33 of the processor 30 or the CPU and power consumption changes over the period of time during which the iterative runs of the workload are conducted are identified from a result of the analysis 640. The method then includes generating a regression profile at the comparator 33 based on the power consumption changes 650. Finally, a policy manager 34, which is coupled to the comparator, manages the software components in accordance with the regression profile 660.
With reference to
The graph of
In accordance with various embodiments of the invention, whether a power consumption level increase or decrease is judged to be significant or not can be determined automatically in view of a default setting, automatically in view of a predefined threshold and/or manually. That is, a default setting may be employed to set forth that a power increase or decrease following a software modification is only to be considered significant if it represents, e.g., at least a 10% change in a power consumption level at a device relative to a previous power consumption level at that device. Conversely, it is to be understood that a developer, who is developing a code patch that is expected to increase power consumption levels in return for added functionality, could manually set forth that, e.g., only power consumption level increases of 20% or more should be considered significant.
The regression profile generated at operation 650 sets forth information which is, at least, indicative of those software modifications that result in significant power consumption level increases and decreases. The regression profile is then transmitted to the policy manager 34 where the software components of the software repository 36 can be managed accordingly. The management may include deleting the modification and/or alerting the relevant developers if it is found that the modification can be associated with a significant increase in power consumption levels that is not, for example, balanced by an appropriate level of additional software functionality. Such an alert could serve to advise the developers of coding practices that are not necessarily positive. Alternatively, the modification could be amended, such that the power consumption level increase is reduced or such that a less power intensive device is actuated in the execution of the modification. Still further, in an event the modification is associated with a power consumption level decrease or insignificant increase, the modification could be committed. Here, the management may further include alerting the developers as to positive coding practices such that they can be employed in future modifications.
While the disclosure has been described with reference to exemplary embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the disclosure. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the disclosure without departing from the essential scope thereof. Therefore, it is intended that the disclosure not be limited to the particular exemplary embodiment disclosed as the best mode contemplated for carrying out this disclosure, but that the disclosure will include all embodiments falling within the scope of the appended claims.
