there has been increasing interests in processing large-scale real-world graphs, and recently many graph systems have been proposed. Vertex-centric GAS (Gather-Apply-Scatter) and Edge-centric GAS are two graph computation models being widely adopted, and existing graph analytics systems commonly follow only one computation model, which is not the best choice for real-world graph processing. In fact, vertex degrees in real-world graphs often obey skewed power-law distributions: most vertices have relatively few neighbors while a few have many neighbors. We observe that vertex-centric GAS for high-degree vertices and edge-centric GAS for low-degree vertices is a much better choice for real-world graph processing. In this paper, we present Mermaid, a system for processing large-scale real-world graphs on a single machine. Mermaid skillfully integrates vertex-centric GAS with edge-centric GAS through a novel vertex-mapping mechanism, and supports streamlined graph processing. On a total of 6 practical natural graph processing tasks, we demonstrate that, on average, Mermaid achieves 1.83x better performance than the state-of-the-art graph system on a single machine.

the 15th Annual ieee/acminternationalsymposium in cluster, cloud, and gridcomputing (ccgrid 2015) brought together international researchers, developers, and practitioners to present leading research activities and results on a broad range of topics. the 2017 Special Issue of Future Generation Computer Systems discusses papers from this conference. Podzimek and colleagues present a tool that accurately controls the processor utilization of arbitrary concurrent workloads, either establishing a constant partial load or replaying a variable load trace, to facilitate experiments at partial utilization. Zhang and colleagues present the system architecture of Lark and its implementation as a plugin of HTCondor, which is a popular HTC software project. Deshpande and Keahey address the problem of network contention between Virtual Machine (VM) application traffic and migration traffic for the live migration of co-located Virtual Machines. Zahid and co-researchers present two significant extensions to their previously proposed partition-aware fat-tree routing algorithm, pFTree, for InfiniBand-based HPC systems. they extend pFTree to incorporate provider defined partition-wise policies that govern how the nodes in different partitions are allowed to share network resources with each other
In this paper, we address the problem of allocating disk resources to guarantee specified latency and throughput targets of VMs while keeping efficient disk I/O. Accordingly, we present two-level scheduling framework,...
