Focusing on data reliability, we propose a control theory centric approach designed to improve transient error resilience in shared caches of emerging multicores while satisfying performance goals. The proposed scheme takes, as input, two quality of service (QoS) specifications: performance QoS and reliability QoS. The first of these indicates the minimum workload-wide cache (L2) hit rate value acceptable, whereas the second one captures the reliability bound on an application basis, with the… CONTINUE READING
