ATLAS Analytics

Overview

The ATLAS Analytics effort is focused on creating systems which provide ATLAS Distributed Computing (ADC) with new capabilities for understanding distributed systems and overall operational performance. These capabilities include:

• Correlate information from multiple systems (PanDA, Rucio, FTS, Dashboards, Tier0, PilotFactory, ...)
• Predictive Analytics: Execute arbitrary data mining or machine learning algorithms over raw and aggregated data
• Ability to host new third party analytics services on a scalable compute platform
• Satisfy variety of use cases for different user roles for ad-hoc analytics
• Provide an open platform with documented collections and tools to broaden participation in ADC Analytics.

Organisation

• Meeting: ADC Analytics Weekly (Indico), usually Wednesdays 16:00-18:00 CEST (40-R-402) - on a biweekly basis: one week is dedicated to Monitoring, the following week to Analytics
• Vidyo: ADC_Analytics
• General purpose e-group: atlas-adc-data-analytics
• Machine learning e-group: atlas-adc-machine-learning
• Ticketing: ATLASMINER JIRA
• Code repository: Github

Clusters and Resources

• analytix cluster at CERN, access to hadoop: In order to get the access you have to be in ai-hadoop-users e-group which is managed by CERN-IT. To get access you need to open a Snow ticket to Hadoop Service, providing your lxplus user name.
• es-atlas: The default Kibana is read-only. Use https://es-atlas.cern.ch/kibana_rw to save dashboard and visualisations.
• UChicago Kibana: default istance is read-only. For write access use: http://atlas-kibana-dev.mwt2.org.
