Query: dynamicMF: A Matrix Factorization Approach to Monitor Resource Usage in
  High Performance Computing Systems   High performance computing (HPC) facilities consist of a large number of
interconnected computing units (or nodes) that execute highly complex
scientific simulations to support scientific research. Monitoring such
facilities, in real-time, is essential to ensure that the system operates at
peak efficiency. Such systems are typically monitored using a variety of
measurement and log data which capture the state of the various components
within the system at regular intervals of time. As modern HPC systems grow in
capacity and complexity, the data produced by current resource monitoring tools
is at a scale that it is no longer feasible to be visually monitored by
analysts. We propose a method that transforms the multi-dimensional output of
resource monitoring tools to a low dimensional representation that facilitates
the understanding of the behavior of a High Performance Computing (HPC) system.
The proposed method automatically extracts the low-dimensional signal in the
data which can be used to track the system efficiency and identify performance
anomalies. The method models the resource usage data as a three dimensional
tensor (capturing resource usage of all compute nodes for difference resources
over time). A dynamic matrix factorization algorithm, called dynamicMF, is
proposed to extract a low-dimensional temporal signal for each node, which is
subsequently fed into an anomaly detector. Results on resource usage data
collected from the Lonestar 4 system at the Texas Advanced Computing Center
show that the identified anomalies are correlated with actual anomalous events
reported in the system log messages.
