Fine-Grained Isolation for Scalable, Dynamic, Multi-tenant Edge Clouds

Yuxin Ren, Guyue Liu, Vlad Nitu, Wenyuan Shao, Riley Kennedy, Gabriel Parmer, Timothy Wood, Alain Tchana
2020 USENIX Annual Technical Conference  
In this paper we introduce EdgeOS that emphasizes systemwide isolation as fine-grained as per-client.  ...  Unfortunately, today's operating system designs fail to meet the goals of scalable isolation, dense multitenancy, and high performance needed for such applications.  ...  We are also thankful to Phani Kishore Gadepalli, Zheng Yang and Runyu Pan for their help on the Composite system.  ...

A Survey of Multi-Tenant Deep Learning Inference on GPU [article]

Fuxun Yu, Di Wang, Longfei Shangguan, Minjia Zhang, Chenchen Liu, Xiang Chen
2022 arXiv   pre-print
This survey aims to summarize and categorize the emerging challenges and optimization opportunities for multi-tenant DL inference on GPU.  ...  However, achieving efficient multi-tenant DL inference is challenging which requires thorough full-stack system optimization.  ...  Such graph and runtime-level operator scheduling could usually achieve better performance due to the fine-grained design, but they also face more scalability issues, e.g., when the number of co-located  ...

GANA-VDC: Application-Aware with Bandwidth Guarantee in Cloud Datacenters

Saleem Karmoshi, Shuo Wang, Naji Alhusaini, Jing Li, Ming Zhu, Ammar Hawbani
2019 Electronics  
GANA-VDC achieves scalability using an interceptor to translate OpenFlow features to prompt fine-grained Quality of Service (QoS).  ...  However, cloud-computing providers offer no network bandwidth guarantees in a cloud environment, predictably preventing tenants from running their applications.  ...  Thus, the imperative exists to provide bandwidth guarantees for VDC under the premise of application-aware networking and the feasibility of fine-grained traffic control for tenants in cloud data centers  ...

2014 Proceedings of the 2014 ACM SIGCOMM workshop on Distributed cloud computing - DCC '14  
It utilizes MPLS label forwarding and aggregation in the network core and uses source routing at the network edge to realize middlebox policies specified by tenants.  ...  (c) They must allow tenants to bring their own IP address space to the cloud to ease transition of enterprise applications and middlebox configuration.  ...  We also show how, through installation of fine-grained forwarding entries for popular destinations, we can further improve performance.  ...
