3-3 Development of 1.2 GHz/2.3 GHz FPU

Branch Write Back SRU FPU 3 FPU 2 FPU 1 FX

This paper presents the performance of DSP, image and 3D applications on recent general-purpose microprocessors using streaming SIMD ISA extensions (integer and oating point). The 9 benchmarks benchmark we use for this evaluation have been optimized for DLP and caches use with SIMD extensions and data prefetch. The result of these cumulated optimizations is a speedup that ranges from 1.9 to 7.1...

GHz VLBI OBSERVATIONS OF 3 C 120

We present the first 86 GHz VLBI observations of the radio galaxy 3C 120, together with contemporaneous 43 and 22 GHz polarimetric VLBA observations. The very high angular resolution obtained at 86 GHz provides an upper limit to the size of the core of 54 mas (0.025 h pc). This represents a direct determination of the base of the jet that is independent of variability arguments (which depend on...

Cbn 12-3

We consider the dynamics of muons injected into the g-2 ring now under construction at FERMILAB. We present the concept for the pulsed injection kicker magnet that optimizes capture efficiency and minimizes coherent betatron oscillations of stored muons. Some engineering details of the high voltage kicker and pulser are presented.
