Recent studies show that cache memories are among the most vulnerable components to soft errors within high-performance processors. Accurate modeling of the Vulnerability Factor (VF) is an essential step towards developing cost-effective protection techniques for cache memory. Although Fault Injection (FI) techniques can provide relatively accurate VF estimations they are often very time consuming. To overcome the limitation, recent analytical models were proposed to compute the cache VF in a timely fashion. In this paper, we extend previous work and propose an alternative analytical model to compute System-level Vulnerability Factor (SVF) for both write-through and write-back data caches. In our proposed analytical model, we take into account both read frequency and error masking to compute system-level vulnerability of data cache. Previously suggested modeling techniques overlook the issues of read frequency and error masking, mainly focusing on time periods in which an error could propagate in the system. In this work we show that overlooking these two parameters can significantly impact the system-level VFs for data caches. We report our estimations for SPEC’2K benchmarks and compare to previously suggested models. Our experimental results show that the proposed modeling technique changes previous VF estimations by up to 40%.","PeriodicalId":382974,"journal":{"name":"2010 IEEE 16th Pacific Rim International Symposium on Dependable Computing","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121875462","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 use Eucalyptus as cloud management software to manage virtual machines designed based on QEMU, called FaultVM, which have a fault injection mechanism. D-Cloud enables the test procedures to be automated using a large amount of computing resources in the cloud by interpreting the system configuration and the test scenario written in XML in D-Cloud front end and enables tests including hardware faults by emulating hardware faults by FaultVM flexibly. In the present paper, we describe the customization facility of FaultVM used to add new device models. We use SpecC, which is a system description language, to describe the behavior of devices, and a simulator generated from the description by SpecC is linked and integrated into FaultVM. This also makes the definition and injection of faults flexible without the modification of the original QEMU source codes. This facility allows D-Cloud to be used to test distributed systems with customized devices.","PeriodicalId":382974,"journal":{"name":"2010 IEEE 16th Pacific Rim International Symposium on Dependable Computing","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128867855","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 proposed method investigates flits in each packet to minimize the number of harmful transition patterns appearing on the communication channels of NoC. To do this, the content of every flit is rotated with respect to the previously flit sent through the channel. Rotation is done to find a rotated version of the flit which minimizes the number of harmful transition patterns. A tag field is added into the rotated flit to enable the receiving side to recover the original flit. Maximum number of rotations is bounded by a fixed value to minimize the timing and power overheads of the proposed method. Evaluation of the proposed method is done in both analytical and simulation manners. VHDL-based simulations are carried out for several channel widths and several tag widths. Simulation results confirm that the proposed method effectively overcomes the cross talk problem while its timing and power overheads are negligible. Results of analytical evaluation are also in agreement with the simulation results.","PeriodicalId":382974,"journal":{"name":"2010 IEEE 16th Pacific Rim International Symposium on Dependable Computing","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126558130","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}
