COMeT+ swMATH ID: 20557 Software Authors: Rahman, Musfiq; Childers, Bruce R.; Cho, Sangyeun Description: COMeT+: continuous online memory testing with multi-threading extension. oday’s computers have gigabytes of main memory due to improved DRAM density. As density increases, smaller bit cells become more susceptible to errors. With an increase in error susceptibility, the need for memory resiliency also increases. Self-testing of memory health can proactively check for errors to improve resiliency. This paper describes a software-only self-test to continuously test memory. We present the challenges and design for an approach, called Continuous Online Memory Testing with Multi-threading Extension (COMeT+), that targets chip multiprocessors. COMeT+ tests memory health simultaneously with execution of single and multi-threaded applications in anticipation of allocation requests. The approach guarantees that memory is tested within a fixed time interval to limit exposure to lurking errors. We developed and evaluated an implementation of COMeT+. On the SPEC CPU2006 and the PARSEC benchmarks, COMeT+ has a low 4 Homepage: http://ieeexplore.ieee.org/abstract/document/6484057/ Related Software: Cited in: 1 Publication Standard Articles 1 Publication describing the Software, including 1 Publication in zbMATH Year COMeT+: continuous online memory testing with multi-threading extension.
