Specifically, we propose to develop a framework that includes an integrated development environment (IDE) for defining rules, and, given a set of rules, generates code for a CEP application and enables us to determine time bounds on the response of this application to a set of supported events. In particular, the IDE helps determine a time bound for the execution time of the code corresponding to each rule. The calculation of time bounds is based on a set of benchmark measurements to be performed on the target hardware and involves code segments corresponding to basic operations. Although we assume the code generation phase produces Java™ code, the same approach can be applied to any other suitable programming language. In support of a feasibility argument for the proposed approach, we present some preliminary experimental results obtained on a partially implemented tool.","PeriodicalId":55035,"journal":{"name":"IBM systems journal","volume":"47 2","pages":"251-263"},"PeriodicalIF":0.0,"publicationDate":"2008-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1147/sj.472.0251","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68013563","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 response to the demand for accelerated access to such features in a Linux™ kernel, the IBM Linux and Java™ Technology Centers collaborated to provide the first commercially available enterprise real-time Linux kernel with real-time Java support. Extending the PREEMPT RT patch from Ingo Molnar of Red Hat, Inc., the kernel contains additional features that were required to meet the demands of enterprise real-time OS customers. This paper describes how IBM developers helped to direct, implement, and test the real-time Linux kernel, bringing it from software patches to a finished product in nine months.","PeriodicalId":55035,"journal":{"name":"IBM systems journal","volume":"47 2","pages":"207-220"},"PeriodicalIF":0.0,"publicationDate":"2008-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1147/sj.472.0207","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68013574","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}

Also presented is information on several IT management disciplines that are critical to achieving high levels of availability. The objective is to enable accelerated adoption and success with the new Power Systems platform by explaining how the technologies can be used to improve IT availability. We define the underlying dependencies required to implement the new live partition mobility and the live application mobility features and show how the environment can be best designed for planned maintenance. Until now, the concept of server virtualization in the UNIX® environment has been limited to a single server, but the Power Systems platform extends the virtualization realm. A brief discussion is given comparing software clustering with the new mobility features and illustrating how they are complementary.","PeriodicalId":55035,"journal":{"name":"IBM systems journal","volume":"47 4","pages":"519-533"},"PeriodicalIF":0.0,"publicationDate":"2008-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1147/SJ.2008.5386517","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68033288","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}

This paper presents three interrelated frameworks as a first attempt to define the fundamentals of service systems. These frameworks identify basic building blocks and organize important attributes and change processes that apply across all service systems. Although relevant regardless of whether a service system uses information technology, the frameworks are also potentially useful in visualizing the realities of moving toward automated service architectures. This paper uses two examples, one largely manual and one highly automated, to illustrate the potential usefulness of the three frameworks, which can be applied together to describe, analyze, and study how service systems are created, how they operate, and how they evolve through a combination of planned and unplanned change.","PeriodicalId":55035,"journal":{"name":"IBM systems journal","volume":"47 1","pages":"71-85"},"PeriodicalIF":0.0,"publicationDate":"2008-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1147/sj.471.0071","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67993175","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}

This is due not only to specialization in direct material production and services offered, but also in the ownership and management of resources, the role of intangible assets such as process knowledge, and the context in which goods and services are consumed. This increase in complexity represents both a challenge and an opportunity in a service-oriented economy. In this paper, we offer a descriptive structure for the analysis of this complexity which combines graph theory and network flows with economic tools. Our analysis is based on publicly observable information and can be used to analyze service systems in terms of the value they deliver, how they deliver it, and how value can be discovered and increased. We show how this analysis can be applied (in the example of a car manufacturer and its service system for suppliers and dealerships) to improve customer satisfaction and provide options and analysis models for outsourcing decision makers.","PeriodicalId":55035,"journal":{"name":"IBM systems journal","volume":"47 1","pages":"87-100"},"PeriodicalIF":0.0,"publicationDate":"2008-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1147/sj.471.0087","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67993177","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 this paper, we present a minimal messaging system, implemented in Java™, that is designed to enable the analysis, modeling, and calibration of the expected performance of these technologies. We describe the algorithms and protocols that underlie this messaging system, show how an analysis can be performed, and give the actual measured performance figures. We show that the system achieves a throughput of more than 100,000 messages per second with less than 120-millisecond maximum latency, in the test environment. At 10,000 messages per second, a maximum latency of 5 milliseconds is measured. The algorithms make use of lock-free data structures, which allow the throughput to scale on multi-core systems.","PeriodicalId":55035,"journal":{"name":"IBM systems journal","volume":"47 2","pages":"237-250"},"PeriodicalIF":0.0,"publicationDate":"2008-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1147/sj.472.0237","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68013572","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}

There are a number of trends that are accelerating the adoption of responsive systems: timeliness requirements for business information systems are becoming more prevalent, embedded systems are increasingly integrated into soft real-time command-and-control systems, improved message-oriented middleware is facilitating growth in event-processing applications, and advances in service-oriented and component-based techniques are lowering the costs of developing and deploying responsive applications. The use of responsive systems is illustrated here in two application areas: the defense industry and online gaming. The papers in this special issue of the IBM Systems Journal are then introduced. The paper concludes with a discussion of the key remaining challenges in this area and ideas for further work.","PeriodicalId":55035,"journal":{"name":"IBM systems journal","volume":"47 2","pages":"197-206"},"PeriodicalIF":0.0,"publicationDate":"2008-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1147/sj.472.0197","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68013569","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}
