DC Proposal: Towards a Framework for Efficient Query Answering and Integration of Geospatial Data [chapter]

Patrik Schneider
2011 Lecture Notes in Computer Science  
We propose a two-tier design related to HEX-programs, which should lead to a plausible trade-off between modularity and efficiency.  ...  Having the integration in place, users might not just issue a points-of-interest search, but rather might be interested in regions with specific attributes assigned to them.  ...  We identify a two-tier design to achieve a good trade-off between modularity and scalability. Tier 1. The first tier is concerned with DL reasoning extended with point-and rangebased spatial queries.  ...

Designing Efficient Cooperative Caching Schemes for Multi-Tier Data-Centers over RDMA-enabled Networks

S. Narravula, H.-W. Jin, K. Vaidyanathan, D.K. Panda
2006 Sixth IEEE International Symposium on Cluster Computing and the Grid (CCGRID'06)  
Caching has been a very important technique in improv- ing the performance and scalability of web-serving datacenters.  ...  In particular, we design schemes that take advantage of the RDMA capabilities of networks and the multitude of resources available in modern multi-tier data-centers.  ...  We implement our system over InfiniBand using Apache Web and Proxy Servers [10] . We further evaluate the various design alternatives using multiple workloads to study the trade-offs involved.  ...

ODISSEA: A Peer-to-Peer Architecture for Scalable Web Search and Information Retrieval

Torsten Suel, Chandan Mathur, Jo-wen Wu, Jiangong Zhang, Alex Delis, Mehdi Kharrazi, Xiaohui Long, Kulesh Shanmugasundaram
2003 International Workshop on the Web and Databases  
ODIS-SEA is different from many other approaches to P2P search in that it assumes a two-tier search engine architecture and a global index structure distributed over the network.  ...  We describe a prototype system called ODISSEA (Open DIStributed Search Engine Architecture) that is currently under development in our group.  ...  There are trade-offs between efficiency and flexibility that may limit the full realization of this goal, and one of our main research goals is to investigate these trade-offs.  ...

Multi-mode energy management for multi-tier server clusters

Tibor Horvath, Kevin Skadron
2008 Proceedings of the 17th international conference on Parallel architectures and compilation techniques - PACT '08  
Moreover, we rigorously investigate selection of the optimal number of spare servers for each power state, a problem that has only been approached in an ad-hoc manner in current policies.  ...  This paper presents an energy management policy for reconfigurable clusters running a multi-tier application, exploiting DVS together with multiple sleep states.  ...  Intuitively, a trade-off exists between system responsiveness and the ability to exploit sleep states, which should be up to the user to control.  ...
