A Novel Approach for Improving Reliability of Multi-Core Systems— How Asymmetric Aging Can Lead a Way

Abstract

Negative-Bias Temperature Instability (NBTI) has become one of the most drastic reliability threats in modern IC designs. To tolerance NBTI on multi-core systems, previous researchers have proposed various task assignment and/or dynamic voltage frequency scaling algorithms. Most of the proposed methods maintain all cores in the multi-core system under similar aging conditions (symmetric aging). Although these methods can mitigate NBTI, the symmetric aging may reduce the lifetime of a multi-core system. If a critical task (i.e., a task with a tight timing constraint) arrives when the system has already operated for years, it is possible that none of the equivalently aged cores can complete the critical task within its timing constraints. This unavoidable timing failure then will shorten the lifetime of the system. With the above observation, this paper proposes a novel reliability improvement framework which realize the concept of asymmetric aging by task graph Retiming, task Ordering, task Assignment under asymmetric aging, and Dynamic voltage selection (ROAD) for multi-core systems. Experimental results show that our approach can significantly increase the system lifetime with no or insignificant energy overhead.

Abstract

The past few years have seen a paradigm shift towards the cloud. Today, the clouds have matured to the point where enterprises are willing to migrate existing applications to the cloud or to build cloud-native applications. That is quickly changing the landscape of Big Data systems.

It is interesting to see different players in the industry employ various strategies and play their strength. In this talk, I will cover the following topics from multiple angles:

1. Scale-out big data systems

2. No more “big” data. It’s just data.

3. Landscape of commercial open source data analytics software

4. Data Engineer communities

5. Open source software developer communities

6. Will the Cloud kill Open Source? How major cloud providers (AWS, Azure, Google) treat open source software vendors. How open source software vendors (MongoDB, ElasticSearch, Confluent, DataBricks, Cloudera) react to cloud vendors’ strategy.

7. Future and Opportunities.
