BACKGROUND1. Technical Field
The present invention relates to the field of computing devices, and more particularly, to enhancing the efficacy of such devices by scheduling the computer applications associated with such devices.
2. Discussion of Related Art
The majority of existing computer operating systems use a priority-driven scheduler. The scheduling is mostly based on a simple, predefined priority setting within the application itself, and ad-hoc monitoring of real-time process behavior. Thus the priority with which a process or a thread will be processed in the computer is detached in time and context from the actual user need, computer processing (and other resources, including storage reading/writing, network communication) capabilities, knowledge regarding the process itself, the interrelationship between processes, and more. In real-time, these priority settings only arbitrarily relate to the other concurrent processes, often leading to user frustration in his computer usage experience.
While the present scheduling procedure is very limited and largely one dimensional, applications differ greatly on various traits, such as resource requirements over time, mode of use by the user, multiple-process relationship and others. Furthermore, critical factors in the computer's purpose and functionality, for example user requirements and expectations, do not play a part in the scheduling process.

Embodiments of the present invention provide a computer implemented method comprising: classifying a plurality of processes relating to a plurality of applications and using a plurality of computing resources, wherein at least some of the processes relate to a user activity, and wherein the classification is carried our in respect to the user activity; generating a user application use profile by analyzing the user activity in respect to the processes; assigning each process a priority relating to the analysis of the user activity, user preferences, user typical usage hours, and the user application use profile; and scheduling the processes in respect to the assigned priorities such as to enhance processes with a high priority, wherein the scheduling is carried out such as to adapt an allocation of the computing resources to the user application use profile, and wherein at least one of: the classifying; the generating; the assigning; and the scheduling, is performed by at least one computer.
These, additional, and/or other aspects and/or advantages of the present invention are: set forth in the detailed description which follows; possibly inferable from the detailed description; and/or learnable by practice of the present invention.
The present invention will be more readily understood from the detailed description of embodiments thereof made in conjunction with the accompanying drawings of which:
Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of the components set forth in the following description or illustrated in the drawings. The invention is applicable to other embodiments or of being practiced or carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein is for the purpose of description and should not be regarded as limiting.
For a better understanding of the invention, the usages of the following terms in the present disclosure are defined in a non-limiting manner:
The term “computer” as used herein in this application, is defined as a programmable machine that receives input, stores and manipulates data, and provides output in a useful format. A computer comprises at least a processor, a storage and an input/output unit. In particular, in this application, the term “computer” is understood to include any computing or communication device (e.g., mobile phones).
The term “application” as used herein in this application, is defined as computer software designed to help the user to perform a singular or multiple related specific tasks. Typical examples are word processors, spreadsheets, media players and database applications.
The term “process” as used herein in this application, is defined as an instance of an application that is being executed by a computer. The process comprises program code and current activity. Depending on the operating system (OS), a process may be made up of multiple threads of execution that execute instructions concurrently.
Whereas an application is a passive collection of instructions, a process is the actual execution of those instructions. Several processes may be associated with the same application; for example, opening up several instances of the same program often means more than one process is being executed.
The term “operating system” as used herein in this application, is defined as an interface between hardware and user, which is responsible for the management and coordination of activities and the sharing of the resources of a computer, that acts as a host for computing applications run on the machine. One of the purposes of an operating system is to handle the resource allocation and access protection of the hardware. This relieves the application programmers from having to manage these details. Operating systems offer a number of services to application programs and users. Applications access these services through application programming interfaces (APIs) or system calls. By invoking these interfaces, the application can request a service from the operating system, pass parameters, and receive the results of the operation. In the current application, the term operating system is extended to further comprise run-time environments, being collections of software services enhancing the interaction with the operating system, such as virtual machines, interfaces and program libraries.
The invention relates to processes 80 relating to user activities 95 of users 90, and to the processing of applications 82 on computing resources 84, e.g., within an operating system (OS). Current (prior art) typical underlying operation mode of OS scheduling resources distribution per application may comprise the preset priority of the application and ad hoc real-time process behavior determine the scheduling priority, without taking into account actual user requirements and priorities, as well as interrelationship of processes. The scheduler does not analyze nor allocate the processing resources according to a wider view of processing analysis, user behavior, existing process knowledge or any other source.
Database 140 may embody an inventory (“Catalog”) (based on a local/remote database or another repository) compiling information of every object run or processed by the computer (“Catalog Item”), for example software applications, hardware devices, online services, multimedia codecs, web applications, drivers, plug-ins, and more, creating a common basis for data analysis within the computer over time and between different computers. The Catalog enables to attribute specific partial processes to an object, and analyze process behavior in the context of the full catalog item. The aggregated knowledge may be contributed to a central repository for future use by the local computer and other computers utilizing that repository. Examples of the type of information collected for each catalog item may include: a list of related binary executable files, its typical use of resources in different scenarios, its typical method of usage, operational costs when the catalog item resides on the computer, etc.
Database 140 may comprise a managing module 145 arranged to monitor and analyze the relevant real-time and non real-time data regarding process' requirements, processing resources availability and user's priorities, and constantly shape the processing schedule. Managing module 145 may further track the computer and user activity providing real-time and non real-time data regarding process' requirements, processing resources availability and user's priorities.
Managing module 145 may further classify processes 80 in respect to the analyzed user activity 95, and update classification 170 in database 140 accordingly.
Managing module 145 may embody a real-time Computer Processes Tracking Mechanism (CPTM) having means of tracking ongoing computer activity and ongoing user activity (using designated probes, such as a file system driver, user interaction, network activity, etc.) and providing the relevant data for the analysis process.
Data processing system 100 further comprises a profiler 110 arranged to generate a user application use profile by analyzing user activities 195 in respect to processes 180, and to assign each process 80 a priority relating to the analysis of user activity (either real time or long term) 195, user preferences and the user application use profile, user typical usage hours, etc.
Data processing system 100 further comprises a scheduler 120 arranged to schedule processes 80 in respect to the assigned priorities such as to enhance processes 80 with a high priority, and such as to adapt an allocation of computing resources 84 to the user application use profile.
Scheduler 120 may embody Smart Scheduling Component (SSC) including a scheduling algorithm and may receive and analyze the data regarding real-time inputs (such as resources' real-time status; user real-time preferences; process' current resource needs; etc.) and non-real-time inputs (such as typical resource requirements; typical usage method; etc.) per application/process, and create and control the processing schedule accordingly, effectively producing the user's wants in real-time. The analysis of this knowledgebase enables the SSC to create a resource-specific schedule, allocating specific computing resources such as CPU; i/o; RAM; Network; etc. The SSC may be implemented as part of the operating system scheduler, or as an external module by means of a Scheduler Controller Gateway (SCG).
Scheduler 120 may further embody a Scheduler Controller Gateway (SCG) that monitors and controls the communication between the OS and the various active applications demanding processing resources. It serves to enable the SSC, when external to the OS built-in scheduler, to externally control and improve the OS scheduler's prioritization process. External Control of the Scheduler may be achieved, for example, through controls provided by the operating system scheduler itself; or through the implementation of several drivers between the applications and the resources, prioritizing/delaying resource requests (for example—file access driver, network access driver, CPU virtualization etc).
Scheduler 120 may comprise a User & Resource Aware Scheduler (URAS) including the SSC, the CPTM and the Catalog, and may be implemented within the OS scheduler or as a separate module. Implementing URAS within the OS scheduler enables the OS Scheduler to monitor and analyze the relevant real-time and non real-time data regarding process' requirements, processing resources availability and user's priorities, and constantly shape the processing schedule. Implementing URAS as an add-on to the OS scheduler the SCG is made up of individual units acting as regulators unique for each resource, as well as a central unit aggregating and controlling these regulators. By means of the SCG which monitors and controls the communication between the OS and the applications, the SSC constantly uses the regulators to control the resource allocation to different processes and if the OS scheduler supports it—dictates the smart priority list and additional scheduling information to the OS Scheduler.
Advantageously, Scheduler 120 prioritizes different applications with different resource needs—for example one application requires high network, another requires high CPU. Scheduler 120 can prioritize both.
Data processing system 100 may further comprise a scheduling API (application programming interface) 130 designed to allow 3rd party software to improve their scheduling by delegating the internal application scheduling control to a centralized scheduling controller. This element enables the processing of each application's/process's current needs in the broader scope of all running applications, processes and threads' requirements, thereby also enabling resource-specific and/or per-functionality-application-internal scheduling.
Scheduling API 130 may enable, when scheduler 120 is outside the OS, to delegate of the application internal scheduling to the interactive priority setting at the application level based on a broad perspective—a central understanding of all running processes' current requirements. Based on the Catalog, and probes, the CPTM tracks the computer and user activity and integrating the API data, provides real-time and non real-time data regarding process' requirements, processing resources availability and user's priorities. By means of the SCG which monitors and controls the communication between the OS and the applications, the SSC constantly dictates the smart priority list to the OS Scheduler in real-time.
The concept can work in a similar way when the scheduling components are implemented within the OS scheduler to enhance existing OS schedulers.
By one embodiment of the system, the SSC is implemented within the OS scheduler, along with the Catalog and the CPTM. Based on the Catalog information, (which can be derived from a central repository accumulating Catalog Item data from each computer in the system, or added & researched locally), the CPTM is continually tracking and analyzing usage data regarding each active Catalog Item. Such data may be computer resource (e.g. CPU, RAM. Storage I/O, Network, etc.) usage; typical user interaction with that particular item; correlating usage of items; and more. These data serve to deduce users' real-time preferences and the computer processing resources applied to these preferences. Another CPTM probe or set of probes may aggregate the typical usage method, resource requirements and background operation needs of each application. The SSC analyzes both the real-time data (for example: user and usage related real-time data) and the non-real-time data (for example: application typical usage method data) and creates a schedule based on the user preferences and the availability of each of the specifically required various computer processing resources (e.g. CPU, RAM. Storage I/O, Network, etc.). This embodiment displays an intelligent learning system constantly analyzing user and application requirements and their interaction, thereby creating continuously 8 improving intelligent scheduling. This scheduling may be based on real-time user needs, as well as long-term aggregated knowledge of typical application usage by users and typical application usage of resources. In conclusion, the method and system outlined above enable scheduling of computer application processing tailored to the user's preferences. This is brought about through constant tracking of the computer usage, aggregated data regarding typical usage characteristics of a specific application, and a comprehensive analysis of computer processing resources' availability (including, e.g., the time of day, day of week, workday VS non-work, daylight saving time, etc). Together, these mechanisms enable efficient computer usage adapting itself to the specific user in real-time.
