Dwarf novae are a subclass of cataclysmic variable stars in which a late-type secondary fills its Roche lobe and transfers mass to a white dwarf primary via an accretion disc. ... Those spiral structures are very similar to the spiral shocks discovered by Sawada, Matsuda & Hachisu (1986) in 2D finite difference numerical simulations in accretion discs. In this poster, we want to compare 2D numerical simulations of accretion disc with the observations of SH2 . ...

The 2.6 kernel makes extensive use of per-CPU data - arrays containing one object for each processor on the system. Per-CPU variables are not suitable for every task, but, in situations where they can be used, they do offer a couple of advantages: . Per-CPU variables have fewer locking requirements since they are (normally) only accessed by a single processor. ... DEFINE_PER_CPU(type, name); . ...
