"I don't suppose you have a friend who is a warthog. You probably don't have a friend who is a professional detective, either. So it's very unlikely that you have a friend who's both. But I do."So begins the adventures of Nixk Sayga and his friend Bill, a warthog detective, in Full Metal Trench Coat, the first book in the new Bill the Warthog Mysteries series. As Bill fights kid's "crimes," such as investigating celebrity soccer shoes and broken skateboard helmets, he also teaches Nick and his friends about the Armour of God. Kids will love trying to figure out each chapter's mystery as they enjoy the zany antics of Bill, Nick and their friends. And they will laugh at Bill's crazy attempts to fit in with kids, even putting tennis balls on his tusks so he can join the soccer team without risk of injuring the palyers! Bill the Warthog Mysteries: Full Metal Trench Coat will bring laughter and learning to preteens, and kids of all ages!
Service Level Agreements (SLAs) are currently one of the major research topics in Grid Computing, as they serve as a foundation for reliable and predictable Grids. SLAs define an explicit statement of expectations and obligations in a business relationship between provider and customer. Thus, SLAs should guarantee the desired and a-priori negotiated Quality of Service (QoS), which is a mandatory prerequisite for the Next Generation Grids. The complexity of an SLA-based workflow grows significantly, as characteristics of correlated sub-jobs, the data transfer phases, the deadline constraints and possible failures have to be considered. Thus, an architect for an SLA-aware workflow implementation needs sophisticated mechanisms for specification and management, sub-job mapping, data transfer optimization and fault reaction. Therefore, this book presents a system for SLA-aware Grid workflows. The main contributions include an improved specification language for SLA-aware workflows, three mapping and optimization algorithms for sub-job assignment to Grid resources, an error recovery mechanism, and a prototype implementation using standard middleware."
