Diierent Frameworks for Unstructred Cfd Related Adaptive Application
نویسنده
چکیده
The purpose of this paper is to survey the di erent issues regarding runtime load balancing for CFD related application. Di erent execution framework for parallel CFD application is possible. They di er by load balancing algorithm usage. Iterative static graph partition is one solution of this problem. Other solution is to do dynamic load balancing by data migration during runtime as initial mapping using graph partition is no longer su cient in adaptive application. Di erent scheduling techniques are discussed. These techniques can be used as a load balancing for data in CFD application. Fractiling is one of the existing load balancing method that uses scheduling technique (factoring) at the same time exploits data locality.

In the present study, Adaptive Neuro–Fuzzy Inference System (ANFIS) approach was applied for predicting the heat transfer and air flow pressure drop on flat and discontinuous fins. The heat transfer and friction characteristics were experimentally investigated in four flat and discontinuous fins with different geometric parameters including; fin length (r), fin interruption (s), fin pitch (p), ...
متن کاملReasoning with Probabilities , Time And
Over the years probability theory has emerged as the leading way of dealing with uncertainty in AI and Databases. However, application of probabilistic methods to diierent frameworks has always been a problem as the two main goals of such an application | eeciency and correctness | are often at odds with each other. This is so because diierent dependencies between the events considered cause di...

متن کاملFormal Properties of Conditional Independence in Diierent Calculi of Ai
In this paper formal properties of CI in diierent frameworks are studied. The rst part is devoted to the comparison of three diierent frameworks for study CI: probability theory, theory of relational databases and Spohn's theory of ordinal conditional functions. Although CI{models arising in these frameworks are very similar (they satisfy semigraphoid axioms) we give examples showing that their...
