Datacenter Virtualization with Optimization and Customization

Network Function Virtualization in Optical Inter-Datacenter Elastic Optical Networks

We first explain the motivations of studying network function virtualization (NFV) in inter-datacenter elastic optical networks (IDC-EONs). Then, we analyze the challenges for provisioning virtual network function forwarding graphs (vNF-FGs) in IDC-EONs, and give insights on how to customize vNF-FG orchestration and optimize IT and spectrum resource allocations jointly. OCIS codes: (060.1155) A...

Preemptive, Low Latency Datacenter Scheduling via Lightweight Virtualization

Data centers are evolving to host heterogeneous workloads on shared clusters to reduce the operational cost and achieve higher resource utilization. However, it is challenging to schedule heterogeneous workloads with diverse resource requirements and QoS constraints. On the one hand, latency-critical jobs need to be scheduled as soon as they are submitted to avoid any queuing delays. On the oth...

Federated Optimization: Distributed Optimization Beyond the Datacenter

We introduce a new and increasingly relevant setting for distributed optimization in machine learning, where the data defining the optimization are distributed (unevenly) over an extremely large number of nodes, but the goal remains to train a high-quality centralized model. We refer to this setting as Federated Optimization. In this setting, communication efficiency is of utmost importance. A ...

HNVM: Hybrid NVM Enabled Datacenter Design and Optimization

Emerging non-volatile memories (NVMs) like batterybacked DRAM and phase-change memory offer durability at higher speeds than traditional storage. Each technology represents a different point in the cost, performance and endurance space. In this paper, we propose that storage intensive applications use more than one kind of NVM in configurable proportions to strike a balance between cost, perfor...
