Fault injection through accelerated irradiation is an effective way to evaluate the overall soft error resiliency of microprocessors. In this work, we report on irradiation experiments on a Blue Gene/Q (BG/Q) compute processor chip running selected applications. Blue Gene/Q is the third generation of IBM's massively parallel, energy efficient Blue Gene series of supercomputers. In the experiments,...
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 materials. On the other hand, it is well known that...
The Blue Gene/L system at the Department of Energy Lawrence Livermore National Laboratory in Livermore, California is the world’s most powerful supercomputer. It has achieved groundbreaking performance in both standard benchmarks as well as real scientific applications. In that process, it has enabled new science that simply could not be done before. Blue Gene/L was developed by a relatively small...
