Some features of this site may not work without it. 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.

Techniques to mitigate their effect come at a significant cost of area, power, performance, and design effort. Architectural Vulnerability Factor (AVF) modeling has been proposed to easily estimate the processor's soft For most current systems, AVF is an accurate abstraction of the architecture level masking effect.

We analyze the validity of the two steps using both mathematical analysis and experiments.

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.

My dissertation focuses on the modeling and analysis of soft error issues at the architecture level. In order to do that, one would need reasonably accurate estimate of the amount of masking effect in real time. Please try the request again.

  4. The method first calculates the failure rate for an architecture level component as the product of its raw error rate and an architecture vulnerability factor (AVF).
  5. It provides new techniques to examine and take advantage of architecture level soft error behavior.
  6. We explore scenarios in which such discrepancies could occur in practice.
  7. 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.
  8. Image not available.
  9. Our method applies to both logic and storage structures on the processor and does not require complex offline calibration for different workloads.

Microarchitectural simulations are time-consuming, and do not easily provide insight into the mechanisms of interactions between the workload and the microarchitecture to determine AVF, beyond aggregate statistics. These aforementioned challenges In this dissertation, we propose a novel way of estimating AVF online, using simple modifications to the processor. 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. Both steps make significant assumptions.

Thus, it is natural to consider the architecture level solutions to take advantage of such variations. check my blog Equal Opportunity Housing College Classifieds Housing Roommates Sublets For Sale Textbooks Jobs Internships Professor Ratings Scholarships Tutors Study Abroad Student Loans Test Prep College News Sports Campus Life Entertainment Fashion Company We test our method with a widely used simulator from industry for SPEC benchmarks. Existing solutions for estimating AVF are often based on offline simulators and usually hard to implement in real processors.

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. In order to do that, one would need reasonably accurate estimate of the amount of masking effect in real time. This listing has been filled. this content Our results motivate selective and dynamic architecture level soft error protection schemes.

All other rights are reserved by the author(s). Owing to its construction, the model provides fundamental insight into the precise mechanism of interaction between the workload and the microarchitecture to determine AVF. The model is used to cheaply perform AVF modeling is used to identify structures in the processor that have the highest contribution to the overall Soft Error Rate (SER) while running typical workloads, and used to guide the

We apply SoftArch to an out-of-order processor running SPEC2000 benchmarks.

In this dissertation, we propose a novel way of estimating AVF online, using simple modifications to the processor. Existing solutions for estimating AVF are often based on offline simulators and usually hard to implement in real processors. The results show that the method provides reasonably accurate run-time AVF estimates. The methodology induces 1.4X higher SER in the core as compared to the highest SER induced by SPEC CPU2006 and MiBench programs. Second, a first-order analytical model is proposed, which
