Providing Persistent and Consistent Resources through Event Log Analysis and Predictions for Large-scale Computing Systems

چکیده
1.INTRODUCTION The ability to track and analyze every possible fault condition, whether transient (soft) or permanent (hard), is one of the most critical requirements for large-scale cluster computer systems. All such events are generally termed as “RAS Events” (RAS for Reliability, Availability, and Serviceability). Depending on the complexities of the cluster computers, the RAS events must address the logs categorized based on a number of subsystems like (a) CPU subsystem, (b) memory subsystem, (c) power supply subsystem and I/O subsystem[9,10]. The RAS event monitoring not only helps in addressing problems related to hardware maintenance, heartbeat monitoring etc, but also figuring out the role of software system including applications on such events.
