Being an integral part of accelerator software, accelerator description aims to provide an external representation of an accelerator’s internal model and associative effects. As a result, the choice of description formats is driven by the scope of accelerator applications and is usually implemented as a tradeoff between various requirements: completeness and extensibility, user and developer or...

This paper presents an accelerator for k-th nearest neighbor thinning, a run time intensive algorithmic kernel used in recent multi-objective optimizers. We discuss the thinning algorithm and the accelerator architecture with its modules and operation, and evaluate the accelerator with respect to two different application scenarios. The first is an embedded computing scenario where the accelera...

The Unified Accelerator Libraries[1] are designed as a customizable and extendible environment for developing diverse accelerator applications. Its main architectural principle is a separation of physical entities and mathematical abstractions from algorithms. The accelerator algorithms are implemented as classes that share data via Common Accelerator Objects (Element, Bunch, Twiss, etc.). This...

An overview of the framework of Unified Accelerator Libraries (UAL) is presented. The UAL framework is a necessary and logical step in the UAL evolution. It intends to offer a standard-based infrastructure that facilitates compatible and independent implementation of accelerator applications and the development of interoperable Accelerator Simulation Facilities. The paper explain the two major ...

We present a flexible accelerator designed for networking applications. The accelerator can be utilized efficiently by a variety of Network Processor designs. Many Network Processors employ hardware accelerators for implementing key domain-specific tasks. New applications require new tasks, such as pattern matching, to be performed on network packets in real-time. Using our proposed accelerator...

Beam parameter optimization in accelerators involves multiple, sometimes competing, objectives. Condensing these individual objectives into a single figure of merit unavoidably results bias towards particular outcomes, often an undesired way the absence prior knowledge. Finding optimal objective definition then requires operators to iterate over many possible weights and definitions, process th...

One of the most important physics targets for any future electron positron linear collider will be the precision measurements of the top quark properties, and especially the top quark mass. Top-antitop production at threshold provides the ideal environment for making such measurements but is complicated by the machine’s luminosity spectrum and thus needs to be carefully studied to understand th...
