Speed : The Performance Accelerator

Performance of the Accelerator Driver of Jefferson

The driver for Jefferson Lab's kW-level infrared free-electron laser (FEL) is a superconducting, recirculating accelerator that recovers about 75% of the electron-beam power and converts it to radiofrequency power. In achieving first lasing, the accelerator operated "straight-ahead" to deliver 38 MeV, 1.1 mA cw current through the wiggler for lasing at wavelengths in the vicinity of 5 μm. Just ...

Systematic and comprehensive analysis of the dose-response characteristics of a morning quality check of a linear accelerator and an important application of accelerator performance prediction

Background: This paper aimed to analyze the output constancy of a medical linear accelerator using PTW QUICKCHECKwebline and studied the sensitivity of the PTW QUICKCHECKwebline. Materials and Methods:  The paper statistically analyzed the output doses of 6 MV and 10 MV of photons and 6 MeV, 9 MeV, and 12 MeV of electrons from a medical linear accelerator measured before the daily treatment to ...

Hardware accelerator to speed up packet processing in NDN router

A hardware implementation of the pending interest table (PIT) for named data networking (NDN) is presented. One of the major challenges in this research is the per-packet update requirement in NDN packet processing. In general, the data structure of the lookup table is optimized in order to minimize the implementation cost and maximize the lookup performance. However, more computation steps are...

Performance-Portable High-Level Accelerator Programming

The OpenMP API provides a portable model for efficient, high level thread-parallel programming across platforms, vendors, operating systems. We are developing a model with the same advantages to address compute accelerators. In this talk, we explore today’s accelerator landscape, along with the perils of current programming methods. We demonstrate why OpenCL, while impressive and important, doe...
