On Improving Deep Learning Trace Analysis with System Call Arguments

no code implementations11 Mar 2021 Quentin Fournier, Daniel Aloise, Seyed Vahid Azhari, François Tetreault

Such tasks may be used to detect anomalies, pre-train neural networks to improve their performance, and extract a contextual representation of the events.

Automatic Cause Detection of Performance Problems in Web Applications

no code implementations8 Mar 2021 Quentin Fournier, Naser Ezzati-Jivan, Daniel Aloise, Michel R. Dagenais

In this paper, we propose a method of extracting the internal behavior of web requests as well as introduce a pipeline that detects performance issues in web requests and provides insights into their root causes.

Empirical comparison between autoencoders and traditional dimensionality reduction methods

no code implementations8 Mar 2021 Quentin Fournier, Daniel Aloise

The four different dimensionality reduction techniques were separately employed on each dataset to project data into a low-dimensional space.

DepGraph: Localizing Performance Bottlenecks in Multi-Core Applications Using Waiting Dependency Graphs and Software Tracing

no code implementations8 Mar 2021 Naser Ezzati-Jivan, Quentin Fournier, Michel R. Dagenais, Abdelwahab Hamou-Lhadj

In this paper, we use a system level tracing approach to extract a Waiting Dependency Graph that shows the breakdown of a task execution among all the interleaving threads and resources.
