In the early 21st century, interdisciplinary methods that address the interconnected and overlapping determinants of health are needed more than ever for dealing with modern, intractable, complex health problems, such as obesity and chronic disease. The relatively recent explosion of complexity science and systems thinking across a broad range of disciplines promises to bring new insight into the nature of these challenges while providing new methods for grappling with the characteristics specific to complex problems such as nonlinearity, feedback loops, and their chaotic nature. There are varying definitions across these disciplines of complex system, systems approach, and even systems thinking.
Rodrigues Loading preview image Job scheduling policies and their configuration aim to achieve goals such as throughput, response time, utilization levels, and meeting deadlines.
Generally, job schedulers require a human expertise to be configured for achieving good performance. Policies may influence user behavior with respect to job submission and required resources on HPC clusters. For example, HPC clusters have queues for jobs that take short duration to execute, for example jobs that run for less than 6 hours.
These queues usually have higher priority than queues designated to hold jobs that take longer duration, for example, jobs that run for more than 10 hours. Given such policies with respect to different types of queues, users may prefer to submit their jobs to the queue with higher priority, for example, those holding short duration jobs.
Users may also try to divide a job that generally takes longer duration to execute into smaller pieces, so that those jobs can be submitted to the short job queue, and therefore, receive priority in running those jobs.
Another example policy may include allowing a job queue to have access to specialized resources such Graphical Processing Units. Based on such policy, a user may prefer one queue over another queue when submitting a job.
Despite the policies, however, resources may be wasted, which in turn increases use of energy, requires additional acquisition and maintenance of machines, and delays user access to the machines. The method, in one aspect, may include executing a job in a high performance computing system according to a current scheduler configuration, the job associated with a given user.
The method may further include monitoring a problem ticket system for an incoming problem ticket associated with the job. The method may also include, responsive to detecting the incoming problem ticket, reconfiguring the current scheduler configuration to increase one or more resources in the high performance computing system for submitted jobs associated with the given user.
The method may also include, responsive to determining that the difference for each of N number of jobs meets a criterion, reconfiguring the current scheduler configuration to reduce the allocated resources for the submitted jobs associated with the given user.
A high performance computing job scheduler system, in one aspect, may include at least one hardware processor executing a job in a high performance computing system according to a current scheduler configuration, the job associated with a given user.
A storage device may be coupled to the at least one hardware processor and store scheduler configurations, from which the at least one hardware processor retrieves the current scheduler configuration.
The at least one hardware processor may monitor a problem ticket system for an incoming problem ticket associated with the job. Responsive to detecting the incoming problem ticket, the at least one hardware processor may reconfigure the current scheduler configuration to increase one or more resources in the high performance computing system allocated for submitted jobs associated with the given user.
Responsive to determining that the difference for said each of N number of jobs meets a criterion, the at least one hardware processor may reconfigure the current scheduler configuration to reduce the allocated resources, e.

Further features as well as the structure and operation of various embodiments are described in detail below with reference to the accompanying drawings. In the drawings, like reference numbers indicate identical or functionally similar elements.
The system and method may optimize one or more job schedulers of High Performance Computing HPC resources, for example, may implement a job scheduler component e. A job includes specification on how to run an application and specification of resources e.
A job specification, for example, may indicate a number of processors, memory size, disk space size and type of communication network standard, for example: In LSF a system administrator sysadmin may configure queues for different purposes.
For example, an HPC cluster may be configured to have queues that have jobs that are only scheduled at night. In this example, although a user can submit jobs to this queue at any moment, the cluster will only execute them at night.
As another example, suppose a user wants to submit a job that runs on all hosts of a cluster. The user can submit such a job by specifying that the user wants to use all processors available.
A policy in the system may disallow this request on business days, but allow the request on weekends. The scheduler according to the policy will wait until a weekend to effectively execute such a job.Associate of Arts in Criminal Justice. The AA in Criminal Justice Program is designed to address the needs of the Criminal justice and security occupations that require the breadth and depth of knowledge and a continually evolving set of physical, technological, cognitive, and interpersonal skills to navigate a rapidly changing environment.
School Climate: Academic Achievement and Social Behavior Competence. The purpose of this technical brief is to provide an operational and applied overview of school climate that can guide decisions related to policy, professional development, and practice and systems implementation at the classroom, school, district, and state levels (by Center for Positive Behavioral Interventions and Supports).

A body or collection of knowledge that is of most use in giving definitions and explanation to the profession of nursing is referred to as a nursing theory. Theories are based on assumptions made up of models, concepts, definitions, and propositions. Croyle () defines a good theory as one that.
Social learning theory explains human behavior in terms of continuous reciprocal interaction between cognitive, behavioral, and environmental influences. Necessary conditions for effective modeling.
