As it is impossible for every bit in the processor to simultaneously contain corruptible state, the worst-case realizable SER while running a workload is less than the sum of their circuit-level
Our results motivate selective and dynamic architecture level soft error protection schemes. To find an alternative model that is not subject to such limitations, we propose a model and tool called SoftArch that does not make the above AVF+SOFR assumptions. It provides new techniques to examine and take advantage of architecture level soft error behavior. Your new password has been sent to your email!

We test our method with a widely used simulator from industry for SPEC benchmarks. http://southtexascollege.uloop.com/textbooks/view.php/1243515058/Soft-Error-Modeling-and-Analysis-for-Microprocessors For most current systems, AVF is an accurate abstraction of the architecture level masking effect. We explore scenarios in which such discrepancies could occur in practice. Next, the method calculates the system failure rate as the sum of the failure rates (SOFR) of all components, and the system MTTF as the reciprocal of this failure rate.

We also propose an efficient online AVF estimation algorithm. My dissertation focuses on the modeling and analysis of soft error issues at the architecture level. Existing solutions for estimating AVF are often based on offline simulators and usually hard to implement in real processors. this content We find that although the AVF+SOFR method is valid for most current systems under current raw error rates, for some cases it can lead to significant discrepancies.
By using the SoftArch tool, we observe that there is much architecture level masking and that the degree of such masking can vary significantly across workloads, individual units, and workload phases. SoftArch is based on a probabilistic model of error generation and propagation process in a processor. The system returned: (22) Invalid argument The remote host or network may be down.
Next, as another application, we quantify the impact of technology scaling on the processor soft error rate, taking the architecture level masking and workload characteristics into consideration. In this dissertation, we propose a novel way of estimating AVF online, using simple modifications to the processor. To sum up, this dissertation studies the architecture level soft error modeling and analysis problems. Some features of this site may not work without it.
The Mean Absolute Error in determining AVF of a 4-wide out-of-order superscalar processor using model is less than 7% for each structure, and the Normalized Mean Square Error for determining overall Image not available.

Additionally, owing to the lack of an intuitive model, AVF modeling is reliant on detailed microarchitectural simulations for understanding the impact of scaling processor structures, or design space exploration studies. In this dissertation, we propose a novel way of estimating AVF online, using simple modifications to the processor. You just missed it! We start with the widely used method for estimating the architecture level mean time to failure (MTTF) due to soft errors.
The results show that the method provides reasonably accurate run-time AVF estimates. Email Address Please enter valid Email Address!

For most current systems, AVF is an accurate abstraction of the architecture level masking effect. The results show that the method provides reasonably accurate run-time AVF estimates. The model is used to quantitatively explain results that may appear counter-intuitive from aggregate performance metrics. Generated Fri, 28 Oct 2016 09:16:27 GMT by s_fl369 (squid/3.5.20)
