HME a hybrid memory emulator for studying the performance and energy characteristics of upcoming NVM technologies. HME exploits features available in commodity NUMA architectures to emulate two kinds of memories: fast, local DRAM, and slower, remote NVM on other NUMA nodes. HME can emulates a wide range of NVM latencies and bandwidth by injecting different memory access delay on the remote NUMA nodes. To facilitate programmers and researchers in evaluating the impact of NVM on the application performance, a high-level programming interface is also provided to allocate memory from NVM or DRAM nodes.

Horae is a graph stream summarization structure for efficient temporal range queries. Horae can deal with temporal queries with arbitrary and elastic range while guaranteeing one-sided and controllable errors. More to the point, Horae provides a worst query time of O(log L), where L is the length of query range. Hoare leverages multi-layer storage and Binary Range Decomposition (BRD) algorithm to decompose the temporal range query to logarithmic time interval queries and executes these queries in corresponding layers.

ShareRender is a cloud gaming system that enables fine-grained resource sharing at the frame-level. Existing cloud gaming systems suffer from low GPU utilization in the virtualized environment. Moreover, GPU resources are scheduled in units of virtual machines (VMs) and this kind of coarse-grained scheduling at the VM-level fails to fully exploit GPU processing capacity. ShareRender offloads graphics workloads within VMs directly to GPUs, bypassing GPU virtualization. For each game running in a VM, ShareRender starts a graphics wrapper to intercept frame rendering requests and assign them to render agents responsible for frame rendering on GPUs. Thanks to the flexible workload assignment among multiple render agents, ShareRender enables fine-grained resource sharing at the frame-level to significantly improve GPU utilization. If you want to know more about ShareRender, please refer to our paper in Multimedia 2017. Wei Zhang, Xiaofei Liao, Peng Li, Hai Jin, Li Lin, "ShareRender: Bypassing GPU Virtualization to Enable Fine-grained Resource Sharing for Cloud Gaming".

HMCached is an in-memory K-V store built on a hybrid DRAM/NVM system. HMCached utilizes an application-level data access counting mechanism to identify frequently-accessed (hotspot) objects (i.e., K-V pairs) in NVM, and migrates them to fast DRAM to reduce the costly NVM accesses. We also propose an NVM-friendly index structure to store the frequently-updated portion of object metadata in DRAM, and thus further mitigate the NVM accesses. Moreover, we propose a benefit-aware memory reassignment policy to address the slab calcification problem in slab-based K-V store systems, and significantly improve the benefit gain from the DRAM.

TripeBit is designed based on two important observations. First, it is important to design a storage structure that can directly and efficiently query the RDF graph. This motivates us to design a compact storage and index structure in TripleBit. Second, in order to truly scale the RDF query processor, we need efficient index structures and query evaluation algorithms to minimize the size of intermediate results generated when evaluating queries, especially complex join queries. This leads us to the design decision that we should not only reduce the size of indexes, but also minimize the number of indexes used in query evaluation.

NightWatch is an extension of memory management system that provides general, transparent and low-overhead cache pollution control. NightWatch extends the memory mapping into two types: restrictive-mapping and open-mapping. The restrictive-mapping is used for restricting the pollution effect of the poor locality data, while the open-mapping is used for cache friendly data. When a malloc request arrives, NightWatch will predict the access locality of the to be allocated memory, determine the proper cache demand, and select the right mapping type for the malloc request. NightWatch is based on the observation that data within the same memory chunk or chunks within the same allocation context often share similar locality property. NightWatch embodies this observation by online monitoring current cache locality to predict future behavior and restricting potential cache polluters proactively.

Scube is an efficient summarization structure for skewed graph stream. Two factors contribute to the efficiency of Scube. First, Scube proposes a space and computation efficient probabilistic counting scheme to identify high-degree nodes in a graph stream. Second, Scube differentiates the storage strategy for the edges associated with high-degree nodes by dynamically allocating multiple rows or columns. We conduct comprehensive experiments to evaluate the performance of Scube on large-scale real-world datasets. The results show that Scube significantly reduces the query latency over a graph stream by 48%-99%, as well as achieving acceptable query accuracy compared to the state-of-the-art designs.

Mammoth is a new MapReduce system which aims to improve MapReduce performance using global memory management. We have conducted extensive experiments with comparison against the native Hadoop platform. The results show that the Mammoth system can reduce the total job execution time by 40% in typical cases, without requiring any modifications of Hadoop programs. When a system is short of memory, the performance improvement can be up to 5 times as observed for CPU and I/O intensive applications, such as PageRank. Given the growing importance of supporting large-scale data processing and analysis, and the proven success of the MapReduce platform, the Mammoth system can have a promising potential and impact.

ACStor

In virtualized data centers, the access of virtual disk images (VDIs) is critical for the overall system performance. As the system scales up to a large number of running VMs, the overall network traffic would become unbalanced with hot spots on some VMs inevitably, leading to I/O performance degradation when accessing the VMs. We propose an adaptive and collaborative VDI storage system (ACStor) to resolve the above performance issue, which can dynamically balance the traffic workloads in accessing VDI chunks based on the run-time network state.
