whitepaper Copy Consistency Point recommendations are described for various configurations of two and three cluster grids. The IBM Virtualization Engine TS7700 is a mainframe virtual tape solution implementing a fully integrated, tiered storage hierarchy of...
[16 May 2008]
News The Commission is promoting the intelligent use of tech to improve efficiency in buildings, lighting and power grids in order to make significant inroads into reducing Europe's carbon footprint. The European Commission (EC) is backing the use of...

whitepaper Signal reference grids are automatically specified and installed in data centers despite the fact that they are no longer needed by modern IT equipment. Even when installed, they are typically used incorrectly.
[15 May 2008]
whitepaper Due to the bidirectional and multi-organizational nature of grids, they are particularly susceptible to connectivity problems. Firewalls and Network Address Translators (NATs) cause significant connectivity problems along with benefits such as...

whitepaper When choosing an SOA strategy, corporations must rely on solutions that ensure data availability, reliability, performance, and scalability. This white paper addresses the challenges in selecting an SOA strategy, and how clustered caching can...
[22 Apr 2008]
whitepaper An exciting trend in high-performance distributed computing is the development of widely-distributed networks of heterogeneous systems and devices, known as computational grids. Grid applications use high-speed networks to logically assemble...
[10 Apr 2008]
whitepaper There are many challenges in making Grids a reality, in the sense that they can provide new capabilities in production quality environments. One challenge is to identify the minimal set of such services and another is to scale the services to Grids...
[10 Apr 2008]
whitepaper This paper describes the architecture, implementation and performance of a service for the delivery of dynamic performance information in Grid environments. Based on usage requirements gleaned from real applications being developed as part of the...
[10 Apr 2008]
whitepaper Data handling systems provide the mechanisms needed to support distributed data access across heterogeneous data resources in computational grids and data grids. The requirements for a data handling system can be expressed as “transparencies” that...
[10 Apr 2008]
whitepaper Data-intensive applications over high bandwidth delay product (BDP) networks, such as computational grids, need new transport protocols to support them. As network bandwidth and delays increase, TCP becomes inefficient.
[10 Apr 2008]
whitepaper However, Grids are still the domain of a few highly trained programmers with expertise in networking, high-performance computing, and operating systems. Grid computing provides key infrastructure for distributed problem solving in dynamic virtual...
[10 Apr 2008]
whitepaper The recent introduction of Oracle VM for advanced server virtualization, in combination with storage virtualization features of NetApp such as FlexVol, FlexClone, and FAS deduplication, make it possible to significantly increase server and storage...
[28 Mar 2008]
whitepaper The Service Level Agreement (SLA) based grid superscheduling approach promotes coordinated resource sharing. Superscheduling is facilitated between administratively and topologically distributed grid sites by grid schedulers such as Resource brokers.
[27 Mar 2008]
whitepaper One of the most powerful features of computing grids is the capability of being able to identify and allocate resources needed to build and run an application on demand and in almost real time, without months of negotiation or waiting for the...
[25 Mar 2008]
whitepaper The performance of a parallel algorithm in a very large scale grid is significantly influenced by the underlying Internet protocols and inter-connectivity. Many grid programming platforms use TCP due to its reliability, usually with some...
[03 Mar 2008]
whitepaper Virtualization technologies are available or emerging for all the resources needed to construct virtual grids which would ideally inherit the above mentioned properties. This paper describes the architecture of the first implementation of the In...
[01 Mar 2008]
whitepaper In a sense, Grids are enabled by virtualization, automation and service-orientation technologies and also integrate these technologies into a unifying solution - particularly across functional and organizational boundaries.
[29 Feb 2008]
whitepaper Grid-enable a specific target application, in this case nanoscience, to prove the usefulness of Grids in future scientific and industrial application, and perform experimental deployment of 100 TFLOPS-scale Grids based on the middleware and Grid...
[15 Feb 2008]
whitepaper Currently, most computational grids (systems allowing transparent sharing of computing resources across organizational boundaries) are assembled using human negotiation. This procedure does not scale well, and is too inflexible to allow for large...
[14 Feb 2008]
whitepaper Computational grids such as the Information Power Grid, Particle Physics Data Grid, and Earth System Grid depend on TCP to provide reliable communication between nodes across a Wide-Area Network (WAN).
