Pro ler for Use byParallel
Scheduling algorithms that use application and system knowledge have been shown to be more eeective at scheduling parallel jobs on a multiprocessor than algorithms that do not. This paper focuses on obtaining such information for use by a scheduler in a network of workstations environment. The log les from three parallel systems are examined to determine both how to categorize parallel jobs for...
متن کاملLER Injection Line B2/B4 Study
During the PEP-II LER commissioning run in July 1998 the beam pro le in the tune up dump pro le monitor just before LER injection showed an anomalous parbolic shape. The sextupole component of the eld of bend magnets B2 and B4 in the beginning of the south injection tunnel (SIT) was thought to be the cause of this. An o -line model of the B2/B4 bend magnet eld was created using DIMAD. Results o...
متن کاملSingle Bunch Stability in Pep-ii Ler
Preliminary estimates[?] indicate that single bunch in the LER of the PEP-II B-factory has to be stable, both longitudinally and transversely, at the maximum design bunch current 1.8 mA (beam current 3A). However, realistic wakes of the machine has been constructed only recently using results of the extensive numerical simulations of the vacuum components of the ring[?]. Additional to that, the...
متن کاملOrbit Distortions and Bumps in the Pep-ii Ler Ring*
The PEP-II B-factory has already achieved twice the design daily-integrated luminosity. This is even more remarkable when looking at the beam orbits, especially in the low energy ring (LER). Orbit oscillations with an amplitude of 7 mm have grown over the years. Four attempts to steer them down resulted in a much lower luminosity and were therefore backed out. Finally, in August of 2001, the ma...
متن کاملStrong convergence of some drift implicit Eu - ler scheme
We study the convergence of a drift implicit scheme for one-dimensional SDEs that was considered by Alfonsi [1] for the Cox-Ingersoll-Ross (CIR) process. Under general conditions, we obtain a strong convergence of order 1. In the CIR case, Dereich, Neuenkirch and Szpruch [2] have shown recently a strong convergence of order 1/2 for this scheme. Here, we obtain a strong convergence of order 1 un...
