Tuning Starfish
STARFISH is a parallel le system simulator we built for our research into the concept of disk directed I O In this report we detail steps taken to tune the le systems supported by STARFISH which include a traditional parallel le system with caching and a disk directed I O system In particular we now support two phase I O use smarter disk scheduling increased the maximumnumber of outstanding req...
متن کاملStarfish on Strike
This paper improves the price-performance ratio of ECM, the elliptic-curve method of integer factorization. In particular, this paper constructs “a = −1” twisted Edwards curves having Q-torsion group Z/2× Z/4, Z/8, or Z/6 and having a known non-torsion point; demonstrates that, compared to the curves used in previous ECM implementations, some of the new curves are more effective at finding smal...
متن کاملCrown-of-thorns starfish
Figure 1. Crown-of-thorns starfish and their legacy. (A) A group of crown-of-thorns starfish converge on the remaining small piece of living coral tissue (lc) on the surface of a tabular coral (Acropora sp.) The other coral tissue has just been consumed by the starfish so that only the white skeleton remains (cs). (B) After crown-of-thorns starfish have removed the living coral tissue, the expo...
متن کاملStarFish: highly-available block storage
In this paper we present StarFish, a highly-available geographically-dispersed block storage system built from commodity servers running FreeBSD, which are connected by standard high-speed IP networking gear. StarFish achieves high availability by transparently replicating data over multiple storage sites. StarFish is accessed via a host-site appliance that masquerades as a host-attached storag...
متن کاملVisual navigation in starfish: first evidence for the use of vision and eyes in starfish.
Most known starfish species possess a compound eye at the tip of each arm, which, except for the lack of true optics, resembles an arthropod compound eye. Although these compound eyes have been known for about two centuries, no visually guided behaviour has ever been directly associated with their presence. There are indications that they are involved in negative phototaxis but this may also be...
