On the Convergence of Malleability and the HPC PowerStack: Exploiting Dynamism in Over-Provisioned and Power-Constrained HPC Systems
Eishi Arima, Isaías A. Comprés, Martin Schulz
Recent High-Performance Computing (HPC) systems are facing important challenges, such as massive power consumption, while at the same time significantly under-utilized system resou…
Operational Data Analytics in Practice: Experiences from Design to Deployment in Production HPC Environments
Alessio Netti, Michael Ott, Carla Guillen +2
As HPC systems grow in complexity, efficient and manageable operation is increasingly critical. Many centers are thus starting to explore the use of Operational Data Analytics (ODA…
Resiliency in Numerical Algorithm Design for Extreme Scale Simulations
Emmanuel Agullo, Mirco Altenbernd, Hartwig Anzt +33
This work is based on the seminar titled ``Resiliency in Numerical Algorithm Design for Extreme Scale Simulations'' held March 1-6, 2020 at Schloss Dagstuhl, that was attended by a…
Correlation-wise Smoothing: Lightweight Knowledge Extraction for HPC Monitoring Data
Alessio Netti, Daniele Tafani, Michael Ott +1
Modern High-Performance Computing (HPC) and data center operators rely more and more on data analytics techniques to improve the efficiency and reliability of their operations. The…
DCDB Wintermute: Enabling Online and Holistic Operational Data Analytics on HPC Systems
Alessio Netti, Micha Mueller, Carla Guillen +4
As we approach the exascale era, the size and complexity of HPC systems continues to increase, raising concerns about their manageability and sustainability. For this reason, more…
From Facility to Application Sensor Data: Modular, Continuous and Holistic Monitoring with DCDB
Alessio Netti, Micha Mueller, Axel Auweter +4
Today's HPC installations are highly-complex systems, and their complexity will only increase as we move to exascale and beyond. At each layer, from facilities to systems, from run…
