The Irix 6.5 scheduling system provides intrinsic support for batch processing, including support for guaranteed access to resources and policy-based static scheduling. Long range scheduling decisions are made by Miser, a user level daemon, which reserves the resources needed by a batch job to complete its tasks. Short-term decisions are made by the kernel in accordance with the reservations es...

In this paper, we discuss how to utilize the co-occurrence of answers in building an automatic question answering system that answers a series of questions on a specific topic in a batch mode. Experiments show that the answers to the many of the questions in the series usually have a high degree of co-occurrence in relevant document passages. This feature sometimes can’t be easily utilized in a...

a computer network experiment designed to study a method of making the computing power of a high-speed batch system available to the interactive terminal system user. Com-mazds for effecting the intersystem linkage and network operations are presented. Emphasized are system measurements and system tuning techniques for increasing eficiency. There are numerous large computer installations in the...

Batch reverse osmosis (RO) is a promising approach to high-recovery desalination. It has low energy consumption, but system size increases sharply with recovery because of the need for large work exchange vessel. In this study, we propose compact hybrid batch/semi-batch (HBSRO) incorporating aspects each approach. HBSRO works in three phases, i.e. semi-batch pressurisation phase, batch and fina...

In chemical batch control applications the speciication of how to produce a batch is called a recipe. When several recipes execute concurrently within a plant there is a possibility for circular wait between recipes utilizing shared resources. A circular wait might lead to the loss of an entire batch; this is costly and should therefore be avoided. This work describes the implementation of a di...

Batch service is a kind of specific stochastic service system which has broad application background. However, in practical, batch service exists commonly as one or several steps in a production or business process. Workflow management system (WfMS) is a powerful tool to support business processes modeling and execution. It has gained extensive attention from both industry and academic domain. ...

This paper describes support for batch rekeying in Mykil, a key management system for supporting secure group multicast. Batch rekeying in Mykil allows for substantial reductions in the cost and complexity of rekeying operations, arguably the expensive portion of the system. By accumulating join and leave operations and utilizing an algorithmic approach to minimize the number of necessary rekey...

Computational grids with multiple batch systems (batch grids) can be powerful infrastructures for executing long-running multi-component parallel applications. In this paper, we evaluate the potential improvements in throughput of long-running multi-component applications when the different components of the applications are executed on multiple batch systems of batch grids. We compare the mult...
