To balance multiple scheduling performance requirements on parallel computer systems, traditional job schedulers use many parameters that can be configured to define job or queue priorities. Offering many parameters seems flexible, but in reality tuning the values for the parameters is highly challenging. To simplify the task of resource management, we(More)
To balance performance goals and allow administrators to declaratively specify high-level performance goals, we apply complete search algorithms to design on-line job scheduling policies for workloads that run on parallel computer systems. We formulate a hierarchical two-level objective that contains two goals commonly placed on parallel computer systems:(More)
Fairness is an important issue for parallel job scheduling policies, but has been ignored in most of previous studies. In this paper, we consider two different styles of job fairness: FCFS and EQ. Commonly used summary statistics are applied to different job measures to evaluate the fairness under a wide range of non-preemptive parallel job scheduling(More)
This paper is concerned with the design of goal-oriented scheduling policies that deal with multiple goals on production parallel systems. Several objective models are compared, including two new models that allow an explicit specification of tradeoff among different goals and a hierarchical model studied in our previous paper. We focus on two performance(More)
Personal health record (PHR) becomes a popular research topic nowadays. Many research works have proposed several concepts in managing and organizing a PHR. However, there are several uncertain issues left such as the role of a PHR in emergency situations. In this paper, a solution to handle a PHR information management in emergency situations is proposed.(More)
To handle several online examination settings, a web-based application test management software, namely interactive examination management system (iEMS), is proposed in this paper. The outstanding points of the proposed system are its good architecture designs, ease of uses, rich features, flexibilities and extensibilities. Seven standard types of questions(More)
Medical treatment sometimes requires a case forwarding to a doctor who has a specific expertise. Typically, an electronic medical record (EMS) of a patient can be passed to another doctor without asking the patient because EMS belongs to the healthcare organization. Personal health record (PHR), however, is different because PHR is owned by an individual(More)
Personal Health Records (PHRs) is a system that allows an individual to store and share his/her health related information with others. The PHR owner can control all accesses to his/her data stored on the PHR system. This work aims to propose a privacy-preserved identification scheme to be used in the PHR system during an emergency situation especially when(More)
