Resource Management and Performance Improvement in Virtualized Environments
COM1 Level 3
MR1, COM1-03-19
Abstract:
An increasing number of applications require significant computing power. Such computing resources are often mutualized and provided by the cloud computing infrastructure, which heavily relies on virtualization.
In this talk, I will give an insight into the research efforts that are going on in my group related to resource management in virtualized environments. The presentation will be based on three recent papers:
- The lock holder and the lock waiter pre-emption problems: nip them in the bud using informed spinlocks (I-Spinlock). EuroSys 2017. Boris Teabe, Vlad Nitu, Alain Tchana, Daniel Hagimont.
- Welcome to zombieland: practical and energy-efficient memory disaggregation in a datacenter. EuroSys 2018. Vlad Nitu, Boris Teabe, Alain Tchana, Canturk Isci, Daniel Hagimont.
- Memory flipping: a threat to NUMA virtual machines in the Cloud. InfoCom 2019. Djob Mvondo, Boris Teabe, Alain Tchana, Daniel Hagimont, Noel De Palma.
