The increasing computing requirements for GPUs (Graphics Processing Units) have favoured the design and marketing of commodity devices that nowadays can also be used to accelerate general purpose computing. Therefore, future high performance clusters intended for HPC (High Performance Computing) will likely include such devices. However, high-end GPU-based accelerators used in HPC feature a considerable...
This article gives you a detailed guide for the construction of a Diskless HPC Cluster using Fedora as Operative System. The final purpose of the Cluster is to run both RAMS (Regional Atmospheric Modelling System) and CAMx (Comprehensive Air quality Model with extensions) Numerical Models in a Parallel and/or Grid manner. Themes ranging from CPU Architecture Selection, passing by Operative System...
Modern enterprises employ hundreds of workstations for daily business operations, which consume a lot of energy and thus have significant operating costs. To reduce such costs, dynamic energy management is often employed. However, dynamic energy management, especially that for disks, introduces delays when an accessed disk is in a low power state and needs to be brought into active state. In this...
The 64-bit OS provides ample memory address space that is beneficial for applications using a large amount of data. This paper proposes using a cluster as a memory resource for sequential applications requiring a large amount of memory. This system is an extension of our previously proposed socket-based distributed large memory system (DLM), which offers large virtual memory by using remote memory...
Cluster system can be considered as a solution when high performance system is deployed because cluster system can provide the high performance, mass storage, scalability and so on with relative low cost in comparison with super computer system. For the trusted service against various malicious attacks, the trusted operational environment is very critical in order to guarantee that their services...
Emerging 64 bitOSpsilas supply a huge amount of memory address space that is essential for new applications using very large data. It is expected that the memory in connected nodes can be used to store swapped pages efficiently, especially in a dedicated cluster which has a high-speed network such as 10 GbE and Infiniband. In this paper, we propose the distributed large memory system (DLM), which...
Dispatching a large number of dynamically changing requests directly to a small number of servers exposes disparity between the requests and the machines. In this paper we present a novel approach that dispatches requests to servers through virtual machines, called dispatching requests indirectly through virtual environment (DRIVE). Client requests are first dispatched to virtual machines which are...
This paper is part of a larger project on MOSIX cluster computing. This paper also is a continuation of the previously published paper regarding MOSIX potential performance and threat (M. Hakim, J. Jais, 2008). The main focuses are on MOSIX implementation, survey and benchmark on MOSIX performance. In this paper, the information is presented in a broad to narrow approach, which is from an overview...
OSCAR has matured over the years into a very capable, yet simple high-performance clustering platform solution. Ease of building and administrating a cluster, effective resource management and scalable performance are some of the issues which have gathered a lot of focus in the HPC domain lately. This technical paper describes the integration of OSCAR and PERCEUS, which aims to enable the deployment...
