Key to this resource exchange grid is the use of mobile agents. Each agent represents a client user, carries his/her job requests, searches for resources available for the request, executes the job at suitable computers, and migrates it to others when the current ones have become unavailable for use. All the features of job migration will be encapsulated in a user program wrapper that is implemented on Java layer between a mobile agent and the corresponding user program. The wrapper maintains the complete execution state of the user program, is carried by the mobile agent upon a job migration, and restores its user program its destination. For this purpose, a user program is preprocessed with JavaCC and ANTLR to include check-pointing functions before its execution. These functions periodically save the execution state of a user program into its corresponding program wrapper, which can thus be carried by an agent smoothly.","PeriodicalId":435768,"journal":{"name":"2003 Autonomic Computing Workshop","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126525904","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}

We describe SSM, a self-tuning, self-protecting, and self-healing session state management layer that provides a storage and retrieval mechanism for semi-persistent, serial-access user session state. SSM is fast, scalable, fault-tolerant, and recovers instantly from individual node failures. Any SSM node may be rebooted at any time and there is no special recovery code, so the performance cost of \"eager\" recovery is near zero, simplifying recovery policy management when SSM is integrated into a larger system.","PeriodicalId":435768,"journal":{"name":"2003 Autonomic Computing Workshop","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129421396","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}

Standard services that perform look-up, match-making, scheduling and staging are being developed to address this problem. As active middleware components, these services will allow users to identify and utilize appropriate resources that provide sustainable system- and user-level qualities of service. This paper documents two enhanced match-making services that address the performance implications of executing a particular workload on a given set of resources. These services are based on an established performance prediction system that is employed at both the local (intra-domain) and global (multi-domain) levels to provide dynamic workload steering. These additional facilities bring about significant performance improvements, the details of which are presented with regard to the user-perceived quality of service and to the grid resource utilization.","PeriodicalId":435768,"journal":{"name":"2003 Autonomic Computing Workshop","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122151177","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}

The configuration method is widely used for such integration. However, there are few formalized tools in support of this method for specification, compilation, diagnosis, reasoning, and distributed provisioning. As a result, the practice of this method is very costly and can lead to security failures. This paper presents a technique called Service Grammar for building these tools based on a novel analysis of protocols and distributed algorithms in a domain of interest. The technique is illustrated in the context of a realistic adaptive virtual private network. We show how lower-layer adaptive protocols can be composed to create adaptive behavior at a higher layer.","PeriodicalId":435768,"journal":{"name":"2003 Autonomic Computing Workshop","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126098486","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}

We propose and validate a novel two step approach that exploits the knowledge of the communication structure of the application to address this problem. In the first step, a small set of candidate node groups are selected potential sites applications execution, by analyzing the network status information and the communication patterns used by the application. The second step is based on the concept of a communication skeleton, which is short running program that generates the dominant communication operations of the application it represents. The communication skeleton is executed on all candidate groups of nodes. The node group selected for application execution is the one that achieves the best performance on the communication skeleton. This approach leads to customized node selection and is particularly well suited to situations where available network information is of poor quality or expected communication performance cannot be modeled accurately. We motivate this approach, describe a prototype implementation, and present performance results for NAS parallel benchmarks executing on a shared network testbed.","PeriodicalId":435768,"journal":{"name":"2003 Autonomic Computing Workshop","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122851031","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}

The condition identified here is the following: For a system with a wide and open range of possible configurations to be self healing, it must possess suitable regularities, which can be relied upon to be satisfied by all possible configurations of the system, and which must be invariant of its failures. We observe that self-healing in physical artifacts, as well as in biological systems, are largely based on regularities engendered by the laws of nature. But since laws of nature have no effective sway over the behavior of software, we propose means for imposing artificial laws over a given distributed system, which are designed to induce desired regularities in them. We demonstrate the efficacy of the proposed approach by applying it to a simple example of electronic purchasing in enterprise systems.","PeriodicalId":435768,"journal":{"name":"2003 Autonomic Computing Workshop","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133953115","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}

Here, we discuss the use of a new system, Astrolabe, to automate self-configuration, monitoring, and to control adaptation. Astrolabe operates by creating a virtual system-wide hierarchical database, which evolves as the underlying information changes. Astrolabe is secure, robust under a wide range of failure and attack scenarios, and imposes low loads even under stress.","PeriodicalId":435768,"journal":{"name":"2003 Autonomic Computing Workshop","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114964655","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}
