This paper describes the measured long-term BTI field data from IBM zEnterprise EC12 systems in 32nm High-k/Metal Gate (HKMG) technology using a built-in monitor which is capable of separating the PBTI and the NBTI effects. The BTI monitor is accompanied by a digital thermal sensor in close proximity to correlate the BTI degradation with temperature. Comparable PBTI and NBTI degradation in use condition...
Soft Error Resiliency is a major concern for Petascale high performance computing (HPC) systems. Blue Gene/Q (BG/Q) is the third generation of IBM's massively parallel, energy efficient Blue Gene series of supercomputers. The principal goal of this work is to understand the interaction between Blue-Gene/Q's hardware resiliency features and high-performance applications through proton irradiation of...
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...
