Cluster performance management

Fault-tolerant Cluster Management for Reliable High-performance Computing

Clusters of COTS workstations/PCs are commonly used to implement cost-effective high-performance systems. A central coordinator/manager is often the simplest way to implement many of the operations required for managing these distributed systems. These operations include scheduling of parallel tasks, coordination of access to limited resources, as well as high-level coordination of fault tolera...

Power and Performance Management of GPUs Based Cluster

Power consumption in GPUs based cluster became the major obstacle in the adoption of high productivity GPU accelerators in the high performance computing industry. The power consumed by GPU chips represent about 75% of the total GPU based cluster power consumption. This is due to the fact that the GPU cards are often configured at peak performance, and consequently, they will be active all the ...

CLUSTER ALGEBRAS AND CLUSTER CATEGORIES

These are notes from introductory survey lectures given at the Institute for Studies in Theoretical Physics and Mathematics (IPM), Teheran, in 2008 and 2010. We present the definition and the fundamental properties of Fomin-Zelevinsky’s cluster algebras. Then, we introduce quiver representations and show how they can be used to construct cluster variables, which are the canonical generator...
