Diagnosing causes of performance variations in High-Performance computing (HPC) systems is a daunting challenge due to the systems' scale and complexity. Variations in application performance result in premature job termination, lower energy efficiency, or wasted computing resources. One potential solution is manual root-cause analysis based on system telemetry data. However, this approach has become an increasingly time-consuming procedure as the process relies on human expertise and the size of telemetry data is voluminous. Recent research employs supervised machine learning (ML) models to diagnose previously encountered performance anomalies in compute nodes automatically. However, these models generally necessitate vast amounts of labeled samples that represent anomalous and healthy states of an application during training. The demand for labeled samples is constraining because gathering labeled samples is difficult and costly, especially considering anomalies that occur infrequently. This paper proposes a novel active learning-based framework that diagnoses previously encountered performance anomalies in HPC systems using significantly fewer labeled samples compared to state-of-the-art ML-based frameworks. Our framework combines an active learning-based query strategy and a supervised classifier to minimize the number of labeled samples required to achieve a target performance score. We evaluate our framework on a production HPC system and a testbed HPC cluster using real and proxy applications. We show that our framework, ALBADross, achieves a 0.95 F1-score using 28x fewer labeled samples compared to a supervised approach with equal F1-score, even when there are previously unseen applications and application inputs in the test dataset.

The machine learning-based decision algorithms commonly used in autonomous driving have led to the Safety of the Intended Functionality(SOTIF) issues due to their potential lack of functionality. To address these limitations, we propose M-DRTA, a distributed runtime assurance framework based on machine learning, which can provide safety assurance for multi-autonomous vehicles by making functional improvements to narrow the vehicle safety zone. We secure the entire multi-vehicle driving system by maintaining safety in local vehicles. In the M-DRTA, an independent runtime assurance framework is provided for each autonomous vehicle through redundant functional modules that include a deep neural network-based advanced controller, a recoverable safety controller, and a monitoring and assurance module. Monitor SOTIF risks by identifying trigger conditions, under-function status, etc., and provide safety through permission handover without unduly sacrificing performance. We tested and evaluated M-DRTA for the different number of vehicle states in a driving task. The experimental results show that M-DRTA can strike a proper balance between safety and efficiency compared to the baseline approach.
