Workshop 4 - Wednesday, June 28 from 9:00 to 12:30
Evolution of HPC software environment
Improving resource allocation to reduce data movement overhead in applications with SLURM
Abstract : This presentation will focus on SLURM Workload Manager improvements developed within the COLOC ITEA project (the COncurrency and LOcality Challenge). This project seeks to design, implement and validate new approaches to optimise process placement and data locality management of HPC clusters & applications. During the presentation we will detail the improvements we made to SLURM in order to enable it to select the most suitable set of nodes for a given parallel application.
On one side we will describe how we optimized the I/O filesystem bandwidth management dealing with heterogeneous resources and how we improved data read/write on persistent storage. On the other side, we will show how the integration of Treematch/SLURM enables to optimize data exchanges by matching the resources to the actual application communication pattern. Both functionalities aim at minimizing execution times and optimising the system utilization.

Bio : Yiannis Georgiou is a Software Engineer at BULL-Atos in the HPC Research and Development department, working as the architect for Resource and Job Management Systems. He is an active developer on SLURM workload manager project. His research interests are centered on the problematics of Resource and Job Management in large-scale clusters and clouds such as workload modeling, efficiency, scalability, power management and high throughput computing. He holds an M.S. Degree in Computer Science, obtained in 2006, from the University Joseph Fourier, France and a PhD degree, obtained in 2010, dealing with Resource and Job Management in High Performance Computing, effectuated in collaboration with Bull and INRIA. |
