Virtual Processors as Kernel Interface

by Adam Lackorzynski, Er Warg, Technische Universität Dresden, Michael Peter
"... After virtualization has gained traction in a variety of fields ranging from the desktop computer to datacenter servers, it is likely to make inroads into embedded systems as well. The complexity of a VM implementation depends on the virtualization abilities of the processor used. Unfortunately, the ..."

Multithreaded Virtual Processor on DSM

by unknown authors , 1999
"... 11-Beom Lee Modem superscalar processors exploit instruction-level parallelism (ILP) by issuing multiple instructions in a single cycle because of increasing demand for higher performance in computing. However, stalls due to cache misses severely degrade the performance by disturbing the exploitatio ..."

Cluster computing performances using virtual processors and

by Gianluca Argentini , 2004
"... In this paper I describe some results on the use of virtual processors technology for parallelize some SPMD computational programs in a cluster environment. The tested technology is the INTEL Hyper Threading on real processors, and the programs are MATLAB 6.5 Release 13 scripts for floating points c ..."

Load balancing HPF programs by migrating virtual processors

by Christian Perez - IN SECOND INTERNATIONAL WORKSHOP ON HIGH-LEVEL PROGRAMMING MODELS AND SUPPORTIVE ENVIRONMENTS, HIPS '97 , 1997
"... This paper explores the integration of load balancing features in the data parallel language HPF targeting semi-regular applications. We show that the HPF virtual processors are good candidates to be the unit of migration. Then, we compare 3 possible implementations and show that threads provide a g ..."

A generalized processor sharing approach to flow control in integrated services networks: The single-node case

by Abhay K. Parekh, Robert G. Gallager - IEEE/ACM TRANSACTIONS ON NETWORKING , 1993
"... The problem of allocating network resources to the users of an integrated services network is investigated in the context of rate-based flow control. The network is assumed to be a virtual circuit, connection-based packet network. We show that the use of Generalized processor Sharing (GPS), when co ..."

A Virtual Processor File Interface with Automatic Mode Detection

by Jason A. Moore, Philip J. Hatcher, Michael J. Quinn
"... Parallel computing is facing a software crisis. No abstraction has been found to support programmers in developing applications with consistent high performance on a variety of parallel computers. The situation is worse with respect to parallel I/O. Parallel languages rarely specify parallel I/O con ..."
Abstract - Add to MetaCart
/O constructs, and systems provide the programmer with a very low-level interface. We present design principles for integrating I/O into languages and show how these principles are applied in a virtual-processor-oriented language. We show how machine-independent modes are used to support both high performance
