System crash
We have witnessed the worst global financial crisis in a century and the repercussions are still being felt in developed and developing countries alike. A dangerous cocktail of short-term gains prevailing over long-term interests, herding, increasing pressure to deliver results, the absence of effective oversight, and blind trust that the system would regulate itself eventually exploded when Le...
متن کاملCertifying a Crash-safe File System
File systems are a cornerstone for storing and retrieving permanent data, yet they are complex enough to have bugs that might cause data loss, especially in the face of system crashes. FSCQ is the first file system that (1) provides a precise specification for the core subset of POSIX file-system APIs; and the APIs include fsync and fdatasync, which allow applications to achieve high I/O perfor...
متن کاملSystem crash as dynamics of complex networks.
Complex systems, from animal herds to human nations, sometimes crash drastically. Although the growth and evolution of systems have been extensively studied, our understanding of how systems crash is still limited. It remains rather puzzling why some systems, appearing to be doomed to fail, manage to survive for a long time whereas some other systems, which seem to be too big or too strong to f...
متن کاملCrash Avoidance in a Complex System
Complex systems can exhibit unexpected large changes, e.g. a crash in a financial market. We examine the large endogenous changes arising within a non-trivial generalization of the Minority Game: the Grand Canonical Minority Game (GCMG). Using a Markov Chain description, we study the many possible paths the system may take. This ‘manyworlds’ view not only allows us to predict the start and end ...
متن کاملComputer crash--lessons from a system failure.
Although executives and physicians at the Beth Is-rael Deaconess Medical Center in Boston have had reason to take great pride in their advanced clinical computing system, they recently had a wake-up call when the system suffered a full-scale failure. Before the crash, the medical center's information-systems staff had designed and implemented a variety of applications to aid clinicians in carin...
