摘要:... Recently, heterogeneous processors composed of different types of cores attracted much attention because of their flexible core configuration and high energy efficiency. In this paper, we propose a compressed sparse row (CSR) format based SpMV algorithm utilizing both types...

摘要:Abstract(#br)Efficiently scheduling a set of independent tasks on a virtual supercomputer formed by many heterogeneous components has great practical importance, since such systems are commonly used nowadays. Scheduling efficiency can be seen as the problem of minimizing the over...

摘要:Abstract(#br)The problem of determining whether a set of periodic tasks can be assigned to a set of heterogeneous processors without deadline violations has been shown, in general, to be NP-hard. This paper presents a new algorithm based on ant colony optimization (ACO) metaheuri...

摘要:...(#br)In this work we propose a framework for SpGEMM on GPUs and emerging CPU–GPU heterogeneous processors. This framework particularly focuses on the above three problems. Memory pre-allocation for the resulting matrix is organized by a hybrid method that saves a large ...

摘要:Abstract(#br)The usage of heterogeneous multicore platforms is appealing for applications, e.g. hard real-time systems, due to the potential reduced energy consumption offered by such platforms. However, even in such platforms the power wall phenomena still imposes limits to perf...

摘要:... Processors on corners and edges have fewer communication links, giving more capacity for computation, assuming it is desirable to synchronize computation. This paper is concerned with load balancing under these conditions and the introduction of heterogeneous processors for l...

摘要:Abstract(#br)In a distributed computing environment, the schedule by which tasks are assigned to processors is critical to minimizing the overall run-time of the application. However, the problem of discovering the schedule that gives the minimum finish time is NP-Complete. This ...

摘要:Abstract(#br)Energy efficiency is increasingly critical for multi-core processors and many-core accelerators. In order to increase energy efficiency, chip manufacturers are developing heterogeneous CMP chips.(#br)We present analytical models based on an energy consumption metr...

摘要:Abstract(#br)Efficient task scheduling on heterogeneous distributed computing systems (HeDCSs) requires the consideration of the heterogeneity of processors and the inter-processor communication. This paper presents a two-phase algorithm, called H2GS, for task scheduling on HeDCS...
