چکیده
In this paper we consider recent trends in operating systems and discuss their applicability to high performance computing systems. In particular, we will consider the relationship between lightweight kernels, hypervisors, microkernels, modular kernels, and approaches to building systems with a single system image. We then describe how the Catamount lightweight kernel can be extended to support the Xen hypervisor API. This will, in turn, support use of Linux on the compute nodes of a large scale parallel system while minimizing the effort needed to support both, a lightweight OS and a full-featured OS.

HPC System Call Usage Trends
The changing landscape of high performance computing (HPC) hardware and applications poses a constant challenge to operating system architects. In this paper, we assess operating system evolution on the basis of several key factors related to system call functionality. Results are presented for Linux and Linux-like lightweight kernels. Comparisons are made with several other operating systems e...
متن کاملOn the Applicability of Oxford's Taxonomy of Learner Strategies to Translation Tasks
During the last three decades, especially 1980's, language learning specialists have been busy discovering the nature of language learning strategies, describing them, and formulating their relationships with other language learning factors. In line with these studies, the field of translation studies has undergone a complete revolution in terms of its perspective toward its research prioritie...
متن کاملModels, solution, methods and their applicability of dynamic location problems (DLPs) (a gap analysis for further research)
Determining the best location to be profitable for the facility’s lifetime is the important decision of public and private firms, so this is why discussion about dynamic location problems (DLPs) is a critical significance. This paper presented a comprehensive review from 1968 up to most recent on published researches about DLPs and classified them into two parts. First, mathematical models deve...
متن کاملParavirtualization for Hpc Systems * Ucsb Computer Science Technical Report Number 2006-10
Virtualization has become increasingly popular for enabling full system isolation, load balancing, and hardware multiplexing. This wide-spread use is the result of novel techniques such as paravirtualization that make virtualization systems practical and efficient. Paravirtualizing systems export an interface that is slightly different from the underlying hardware but that significantly streaml...
متن کاملTowards a Lightweight RDMA Para-Virtualization for HPC
Virtualization has gained increasing attention in the recent High Performance Computing (HPC) development. While HPC provides scalability and computing performance, HPC in the cloud benefits in addition from the agility and flexibility that virtualization brings. One of the major challenges of HPC in virtualized environments is RDMA virtualization. Existing implementations of RDMA virtualizatio...
