Fault and Error Latency Under Real Workload - an Experimental Study
type: CreativeWork
description: This thesis demonstrates a practical methodology for the study of fault and error latency under real workload. This is the first study that measures and quantifies the latency under real workload and fills a major gap in the current understanding of workload-failure relationships. The methodology is based on low level data gathered on a VAX 11/780 during the normal workload conditions of the installation. Fault occurrence is simulated on the data, and the error generation and discovery process is reconstructed to determine latency. The analysis proceeds to combine the low level activity data with high level machine performance data to yield a better understanding of the phenomenon. This study finds a strong relationship between latency and workload and quantifies the relationship. The sampling and reconstruction techniques used are also validated.
