Soft errors are becoming a common problem in current systems due to the scaling of technology that results in the use of smaller devices, lower voltages, and power-saving techniques. In this work, we focus on soft errors that can occur in the objects created in heap memory, and investigate techniques for enhancing the immunity to soft errors through various object duplication schemes. The idea is to access the duplicate object when the checksum associated with the primary object indicates an error. We implemented several duplication based schemes and conducted extensive experiments. Our results clearly show that this spectrum of schemes enable us to balance the tradeoffs between error rate and heap space consumption.
