Predicting Node Failure in High Performance Computing Systems from Failure and Usage Logs

In this paper, we apply data mining classification schemes to predict failures in a high performance computer system. Failure and Usage data logs collected on supercomputing clusters at Los Alamos National Laboratory (LANL) were used to extract instances of failure information. For each failure instance, past and future failure information is accumulated -- time of usage, system idle time, time of unavailability, time since last failure, time to next failure. We performed two separate analyses, with and without classifying the failures based on their root cause. Based on this data, we applied some popular decision tree classifiers to predict if a failure would occur within 1 hour. Our experiments show that our prediction system predicts failures with a high-degree of precision up to 73% and recall of about 80%. We also observed that employing the usage data along with the failure data has improved the accuracy of prediction.
