The timeliness requirements of real-time systems, however, impose specific demands on the operational parameters of the garbage collector. The memory requirements of real-time tasks must be accommodated with a predictable impact on the timeline, and under the purview of the scheduler. Utility accrual is a method of dynamic overload scheduling that is designed to respond to CPU overload conditions by producing a schedule that heuristically maximize a predefined metric of utility. There also exists in such systems the possibility of memory overload situations in which the cumulative memory demand exceeds the amount of memory available. This paper presents a utility accrual algorithm for uniprocessor CPU and garbage collection scheduling that addresses memory overload conditions. By tightly linking CPU and memory allocation, the scheduler can appropriately respond to overload along both dimensions. This scheduler is the first of its kind to enable the use of automatic memory management in a utility accrual system. Experimental results using actual Java application profiles indicate the viability of this model","PeriodicalId":212174,"journal":{"name":"Ninth IEEE International Symposium on Object and Component-Oriented Real-Time Distributed Computing (ISORC'06)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131453607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a couple of years ago, we developed a Linux-based real-time kernel, named TMO-Linux, supporting deadline driven executions of TMO's. TMO-Linux and its distributed IPC subsystem have been used well in developing networked control systems consisting of cooperating embedded devices, but there have difficulties in executing some TMO applications accurately due to the lack of timeliness in distributed communications. To overcome this problem, we newly developed a real-time distributed IPC over IEEE1394 for the TMO-Linux kernel. In the new system, predictable delivery services for real-time messages are provided by isochronous transmissions of IEEE1394. To implement predictable delivery services, each node is set to have its own isochronous channel for receiving data that is allocated to a fixed time-slot bandwidth in an IEEE1394 frame. This paper presents an implementation technique for the IEEE1394-based real-time distributed IPC and collaborations of computing nodes using TMO-Linux","PeriodicalId":212174,"journal":{"name":"Ninth IEEE International Symposium on Object and Component-Oriented Real-Time Distributed Computing (ISORC'06)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132673209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To master this omnipresent virtual \"organism\", completely new design and operation paradigms have to evolve. In this paper we discuss how research of our group at the University of Paderborn is providing fundamental principles, methods, and tools to design real-time operating systems for this virtual \"organism\" of the future. Based on our fine-granular library for the construction of reflexive RTOS, the necessary configuration tool and its on-line version are discussed. Next step towards self-coordination is a profile management system to support self-optimization of the RTOS. The included flexible resource manager allows migration of RTOS services dynamically between programmable processors and re-configurable HW. In a final step the RTOS itself can be distributed. Its services are provided by a cluster of instances instead of a single one. This makes a sophisticated dynamically self-optimizing communication system necessary","PeriodicalId":212174,"journal":{"name":"Ninth IEEE International Symposium on Object and Component-Oriented Real-Time Distributed Computing (ISORC'06)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130842135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As embedded systems are increasingly integrating both safety-critical and non-safety critical software functionalities onto a shared hardware platform, a dependability driven integration is desirable. Such an integration approach faces new challenges of mapping software components onto shared hardware resources while considering extra-functional (dependability, timing, power consumption, etc.) requirements of the system. Considering dependability and real-time as primary drivers, we present a systematic resource allocation approach for the consolidated mapping of safety critical and non-safety critical applications onto a distributed platform such that their operational delineation is maintained over integration. The objective of our allocation technique is to come up with a feasible solution satisfying multiple concurrent constraints. Ensuring criticality partitioning, avoiding error propagation and reducing interactions across components are addressed in our approach. In order to demonstrate the usefulness and effectiveness of the mapping, the developed approach is applied to an actual automotive system","PeriodicalId":212174,"journal":{"name":"Ninth IEEE International Symposium on Object and Component-Oriented Real-Time Distributed Computing (ISORC'06)","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123149078","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
