Hypervision is being widely implemented in an effort to control costs and to simplify management through consolidation of servers. It has been recently unraveled that well over a third of virtualization vulnerabilities reside in the hyper-visor, mostly due to hypervisor escape. The exploitation of these vulnerabilities allows an attacker, among other things, to access and/or modify data of other Virtual...
We present a new approach to decrease task preemptions and migrations in optimal global real-time schedules on symmetric multiprocessors. Contrary to classical approaches, our method proceeds in two steps, one off-line to place jobs on intervals and one on-line to schedule them dynamically inside each interval. We propose a new linear programming formulation and a local scheduler which exhibits low...
Images of Titan were acquired with the ADONIS adaptive optics system installed at the ESO 3.6-m telescope in La Silla (Chile). The near-infrared range from 1–2.5 μm was covered in 1994 and 1995 in the methane atmospheric windows at 1.3, 1.6, and 2.0 μm with narrow-band filters and CVF. Diffraction-limited images were obtained (0.14 arcsec at 2 μm), thus allowing us to resolve the Titan disk. We have...
