Antarex HPC Fault Dataset

The Antarex dataset contains trace data collected from the homonymous experimental HPC system located at ETH Zurich while it was subjected to fault injection, for the purpose of conducting machine learning-based fault detection studies for HPC systems. Acquiring our own dataset was made necessary by the fact that commercial HPC system operators are very reluctant to share trace data containing information about faults in their systems. In order to acquire data, we executed benchmark applications and at the same time injected faults in the system at specific times via dedicated programs, so as to trigger anomalies in the behaviour of the applications. A wide range of faults is covered in our dataset, from hardware faults, to misconfiguration faults, and finally to performance anomalies cause by interference from other processes. This was achieved through the FINJ fault injection tool, developed by the authors. The dataset contains two types of data: one type of data refers to a series of CSV files, each containing a set of system performance metrics sampled through the LDMS HPC monitoring framework. Another type refers to the log files detailing the status of the system (i.e., currently running benchmark applications or injected fault programs) at each time point in the dataset. Such a structure enables researchers to perform a wide range of studies on the dataset. Moreover, since we collected the dataset by streaming continuous data, any study based on it will easily be reproducible on a real HPC system, in an online way. The dataset is divided in two parts: the first includes only the CPU and memory-related benchmark applications and fault programs, while the second is strictly hard drive-related. We executed each part in both single-core and multi-core variants, resulting in a total of 4 dataset blocks for 32 days of data acquisition, and 20GB of uncompressed data.
