In addition, many of the original developers of Arjuna have accompanied the system on its journey and had first hand experience in taking this academic research vehicle into a commercial environment. At times the transition has been neither easy nor smooth but it has been interesting from many different perspectives. In this paper we shall attempt to give an overview of how this occurred and illustrate some of the lessons we have learned over the years.","PeriodicalId":171901,"journal":{"name":"USENIX Workshop on Industrial Experiences with Systems Software","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117284030","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}

Traditional linkers process all input files, even if only one or two objects have changed since the previous link. To shorten link time, we have developed an incremental linker for HP-UX which only processes modified files. Users can take advantage of the performance gains without modifying their usage patterns of the existing HP-UX linker since the incremental linker is implemented on top of the regular 64-bit linker. In addition to the tasks of the normal linker, the incremental linker must save extra information about input files, symbols and relocations, allow for the expansion of existing files and addition of new ones by allocating padding spaces in the output file and use this information to perform in-place updates. The results of several different design considerations and tradeoffs are materialized in link-time performance gains of up to thirteen times that of a normal link for large applications.","PeriodicalId":171901,"journal":{"name":"USENIX Workshop on Industrial Experiences with Systems Software","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116147149","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 second issue is solved by the utilisation of an automatic memory reclamation scheme, i.e. a garbage collector.\u0000 In this paper we argue that the careful choice of the programming language, along with an automatic memory reclamation scheme can optimise memory usage, while ensuring that many of the logical errors related to memory can be avoided.","PeriodicalId":171901,"journal":{"name":"USENIX Workshop on Industrial Experiences with Systems Software","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122951462","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}

Inefficient and unnecessary complex marshalling code can almost double communication costs. We have developed an experimental new IDL compiler that produces near-optimal stub code for gcc and the L4 microkernel. The current experimental IDL4 compiler cooperates with the gcc compiler and its x86 code generator. Other compilers or target machines would require different optimizations. In most cases, the generated stub code is approximately 3 times faster (and shorter) than the code generated by a commonly used portable IDL compiler. Benchmarks have shown that efficient stubs can increase application performance by more than 10 percent. The results are applied within IBM's SawMill project that aims at technology for constructing multi-server operating systems.","PeriodicalId":171901,"journal":{"name":"USENIX Workshop on Industrial Experiences with Systems Software","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127322200","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}

A computer server that must encrypt data for thousands of clients before sending it over the network can easily become cryptobound.

It provides a common framework that allows building of a wide variety of tools for doing performance analysis, profiling, coverage analysis, correctness checking, and testing. HP Caliper uses a technology known as dynamic instrumentation, which allows program instructions to be changed on-the-fly with instrumentation probes. Dynamic instrumentation makes HP Caliper easy to use: It requires no special preparation of an application, supports shared libraries, collects data for multiple threads, and has low intrusion and overhead. This paper describes HP Caliper for HP-UX, running on the IA-64 (Itanium) processor. It describes Caliper's architecture, dynamic instrumentation algorithm, and the experiences gathered during its implementation.","PeriodicalId":171901,"journal":{"name":"USENIX Workshop on Industrial Experiences with Systems Software","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132008610","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 present Delta's mid-tier Operational Information Systems (OIS) as an approach for leveraging its legacy operational OLTP infrastructure, to participate in the emerging world of electronic commerce, as well as enable new applications. The approach is to place minimally intrusive 'taps' into the legacy OLTP systems to capture transactions as they occur for consistent replay in the mid-tier OIS. One important issue addressed by our work is the processing, and dissemination of information in the mid-tier system itself, potentially serving hundreds of thousands of access and display points, distributed across a highly geographically distributed system (e.g. airports world wide), and also involving large 'working sets' of operational data, used by applications that require rapid response and also rapid recovery from failures. To address the scaleability, availability, and cost of this OIS infrastructure, we are researching cluster computing techniques, as well as, devising replication and failover techniques. To address the communications scaleability requirements, we are experimenting with novel event-based implementations of information transport and processing, that include reliable multicast variations.","PeriodicalId":171901,"journal":{"name":"USENIX Workshop on Industrial Experiences with Systems Software","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125248364","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 reliability metrics we measured are availability from the standpoint of the host and maintainability from the standpoint of the system operator. We created errors using software fault injection, and measured their impact using a combination of performance measurement techniques and the rehearsal of maintenance procedures. This paper gives three case studies. The first two describe experiments that recreate very specific breakdowns in the software logic, and the third describes an experiment simulating a memory hardware failure that creates unpredictable effects. We found that, taken together, these various techniques gave us a useful picture of how well our cache management software tolerated faults.","PeriodicalId":171901,"journal":{"name":"USENIX Workshop on Industrial Experiences with Systems Software","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128756363","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}
