The three sheets nomograms as computing utility

Managed Utility Computing: The Grid as Management Backplane

Enterprise IT exhibits increasingly complex networked systems and distributed applications, making the task of an IT operator or administrator exceedingly difficult. We argue in the keynote associated with this paper for the necessity of a clean, standardized, service-centric software architecture to automate and facilitate operator tasks throughout the life-cycle of systems and applications. W...

Utility Computing

Utility computing has the potential to revolutionize the way we purchase, organize, and distribute computational power and services. It will do so by offloading resource provisioning to centralized sites that can benefit from economies of scale, careful, failure-resilient construction, flexibility and changeability of hardware choices, and scalable and business-driven management techniques. But...

A Pay-as-Bid Mechanism for Pricing Utility Computing

Encountering the increasing demand for high-performance computational resources in academic as well as commercial organisations, utility computing offers a solution by providing users with on-demand availability of requested computing services. Approaches to the fundamental issue of resource allocation include the use of technical scheduling mechanisms as well as introducing economic ideas into...

The art of nomograms

Background To retrospectively analyse strategies for adjusting refractive surgery plans with reference to the preoperative manifest refraction. Methods We constructed seven nomograms based on the refractive outcomes (sphere, cylinder, axis [SCA]) of 150 consecutive eyes treated with laser in situ keratomileusis for myopic astigmatism. We limited the initial data to the SCA of the manifest ref...
