A spatially triggered dissipative resource distribution policy for SMT processors

Programs take on changing behavior at nmtime in a simultaneous multithreading （SMT） environment. How reasonably common resources are distributed among the threads significantly determines the throughput and fairness performance in SMT processors. Existing resource distribution methods either mainly rely on the front-end fetch policy, or make distribution decisions according to the limited information from the pipeline. It is difficult for them to efficiently catch the various resource requirements of the threads. This work presents a spatially triggered dissipative resource distribution （SDRD） policy for SMT processors, its two parts, the self-organization mechanism that is driven by the real-time instructions per cycle （IPC） performance and the introduction of chaos that tries to control the diversity Of trial resource distributions, work together to supply sustaining resource distribution optimization for changing program behavior. Simulation results show that SDRD with fine-grained diversity controlling is more effective than that with a coarse-grained one. And SDRD benefits much from its two well-coordinated parts, providing potential fairness gains as well as good throughput gains. Meanings and settings of important SDRD parameters are also discussed.

The Role of Medical Word-of-Mouth on Sport Therapists: A Patient Psychological Perspectives

In 21st century, more and more people see medical services of sport therapists as a promising industry due to global aging population and high biotechnology development. Hence, understanding medical word-of-mouth (WOM) process among patients in medical services of sport therapists could be interesting and useful. This study would find out the role of WOM on patients psychology when choosing the sport therapists, understand how patients look for sport therapists’ information and which information source is important to them. As a pioneer, this study would like to improve medical WOM marketing of sport therapists. The authors designed a questionnaire based on how patients choosing sport therapists, including questions search importance of different information sources of sport therapists with medical service decision, and respondents’ psychological demographics. We released 253 questionnaires of judo therapy clinics inTaiwan. More than half of the respondents see sport therapists due to others’ recommendations (referral of family, friends and professionals). Women are more likely to seek medical word-of-mouth information than men;and respondents who think choosing sport therapists are important tend to seek medical word-of-mouth information. Further, patients focus on “therapist’s behavior”, “therapist’s skills”, and “therapist’s ethic”.
