PMOS Revisited

چکیده
The Persistent Mature Object Space, PMOS, garbage collection algorithm is designed to incrementally collect all garbage in a potentially large persistent object store. The goal of the PMOS algorithm is to break the collection of garbage into small enough units so that disruption to the running system is insignificant. PMOS is able to collect the small units in arbitrary orders whilst eliminating cyclic garbage and being able to guarantee progress. In this paper, we present the lessons learnt from our prototype PMOS implementation and outline a strategy for a new implementation that more readily addresses the goals of the PMOS algorithm. A key feature of the new design is the ability to support a wide range of experiments with the policies that may affect the performance of the PMOS algorithm.

Project management offices: A case of knowledge-based archetypes
While Project Management Offices (PMOs) have become a mainstay in organizations, systematic research has not yet been undertaken to study their intricacies. In this paper, we conduct an exploratory and descriptive case study of PMOs, based on our interviews with senior managers and directors of PMOs in 32 IT organizations. The objectives are to: (1) outline the nature and characteristics of PMO...

This work studies the effects of dynamic threshold design techniques on the speed and power of digital circuits. A new dynamic threshold transistor structure has been proposed to improve performances of digital circuits. The proposed switched-capacitor dynamic threshold PMOS (SC-DTPMOS) scheme employs a capacitor along with an NMOS switch in order to effectively reduce the threshold voltage of ...

Growth in the number of PMOs established by the industry over last decade and ever growing body of literature on PMO related research in academia is a clear indication that there is very clear interest of researchers, practitioners and industries across the globe to understand and explore value propositions of PMO. However, there is still a lack of consensus on many critical aspects of PMOs. Wh...
متن کاملAn Efficient Design Approach for Low Leakage with NBTI Aware Analysis
As the technology scales down the leakage current in the circuit increases due to reduction in threshold voltage and Negative Bias Temperature Instability (NBTI) producing aging effect in the circuit. Leakage current and NBTI strongly depends on Input Vector Control Technique (IVC) , but IVC is not effective for larger circuits. Therefore in this paper two new designs (1)Ultra low power diode b...

Drug-induced hypersensitivity syndrome/drug rash with eosinophilia and systemic symptoms (DiHS/DRESS) and Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN) are severe drug eruptions characterized by contrasting clinical pictures. Sequential reactivations of several herpesviruses have exclusively been demonstrated in the former. It remains to be determined, however, why the sequent...
