Modern system design often requires multiple levels of simulation for design validation and performance debugging. However, while machines have gotten faster, and simulators have become more detailed, simulation speeds have not tracked machine speeds. As a result, it is difficult to simulate realistic problem sizes and hardware configurations for a target(More)

Soft Error Resiliency (SER) is a major concern for Petascale high performance computing (HPC) systems. In designing Blue Gene/Q (BG/Q) [8], many mechanisms were deployed to target SER including extensive use of Silicon-On-Insulator (SOI), radiation-hardened latches [7,13], detection and correction in on-chip arrays, and very low radiation packaging(More)
The transformers are designed to transmit and distribute electrical power. Depending on the size of the requirement, replacement costs will be more if any fault occurs. Performing offline and invasive test also added to the replacement cost. Hence there is an increasing need to move from traditional schedule based maintenance programs to condition based(More)
