Addressing thermal nonuniformity in SMT workloads

Jonathan A. Winter, David H. Albonesi
2008 ACM Transactions on Architecture and Code Optimization (TACO)  
To address this, we propose and evaluate DTM mechanisms that exploit the steering-based thread management mechanisms inherent in a clustered SMT architecture.  ...  The third dynamic spreading algorithm is dynamic cluster swapping. This mechanism is very similar to dynamic thread swapping.  ...  Dynamic thread swapping attempts to cool a hot thread by exchanging the clusters that the hot thread is using with the clusters assigned to the colder thread.  ...

A Self-configuration Mechanism for High-Availability Clusters [chapter]

Hocheol Sung, Sunyoung Han, Bok-Gyu Joo, Chee-Wei Ang, Wang-Cho Cheng, Kim-Sing Wong
2006 Lecture Notes in Computer Science  
If the configuration between machines participating in the HA cluster can be automated, services clustered can be provided more efficiently.  ...  For evaluating the performance of the system, we simulated the actions of clusters and defined 2 types of models for this simulation, static clustering model and dynamic clustering model.  ...  The dynamic clustering model is for self-configured clusters. In this model, a primary server can select an optimal backup server as a secondary server at any time.  ...

A software-hardware hybrid steering mechanism for clustered microarchitectures

Qiong Cai, Josep M. Codina, Jose Gonzalez, Antonio Gonzalez
2008 Proceedings, International Parallel and Distributed Processing Symposium (IPDPS)  
In addition, the proposed mechanism outperforms state-of-the-art software-only steering mechanisms by 5% and 10% on average for 2-cluster and 4-cluster machines, respectively.  ...  Highperformance out-of-order processors rely on hardware-only steering mechanisms to achieve balanced workload distribution among clusters.  ...  Hardware-based Mechanisms Most dynamically-scheduled clustered microarchitectures rely on dynamic steering of instructions.  ...

EdgeX: Edge Replication for Web Applications

Hemant Saxena, Kenneth Salem
2015 2015 IEEE 8th International Conference on Cloud Computing  
Our objective is to allow dynamic content to be served from the edge of the network, with low latency.  ...  Specifically, we present an edge-aware dynamic data replication architecture for relational database systems supporting web applications.  ...  Clearly, assigning the Edge/Dynamic policy to clusters is desirable, as it gives the run-time system the freedom to exploit geo-localized access patterns by moving the primary copies of partitions to edge  ...

Scheduling Data Intensive Workloads through Virtualization on MapReduce based Clouds

B Thirumala Rao
2012 International Journal of Distributed and Parallel systems  
The proposed scheduler has been evaluated against Fair Scheduler on virtual cluster built on a physical cluster of 20 machines.  ...  There is a conflict between the scheduling MR jobs to meet deadlines and "data locality" (assigning tasks to nodes that contain their input data).  ...  However, the configuration of a VM can be dynamically adjusted with more or less virtual CPUs than the base VM configuration, while the total cores assigned to the cluster does not change.  ...
