Ns2 project in Yukon Territory
Ns2 project in Yukon Territory the metarules of PARlJLEL enable the specification of either kind of control. However, they are best suited for expressing heuristic preferexes for the purpose of filtering a conflict set of rule instances ns2 project in Yukon Territory and obtaining a subset for concurrent firing. PARULEL has similarities with some existing rule languages, although the flexibility of the system in terms of the ability to customize the ns2 project in Yukon Territory conflict resolution method and the operational semantics in a “programmable” fashion for a particular application is unique. Consider RPL , a rule language with programmable conflict resolution expressed by metarules. Although there are obvious syntactic differences between RPL and PARULEL , there are also fundamental differences between the two.
RPL appears to provide only tjwo mechanisms to express parallelism. The “all” ns2 project in Yukon Territory construct dictates that all instances of a rule should be fired. But this is useful only if all instances of a single rule can be fired at once without conflict, ns2 project in Yukon Territory otherwise one has t,o resort to “fire-one-instance” semantics.
In contrast, PARIJLEL’s metarules provide the means of redacting unwanted instances of the same rule as well as different rules, and firing all that remain in parallel. The “firing group” construct of RPL is its second major construct that, is reminiscent of various rule ns2 project in Yukon Territory partitioning schemes in other earlier work . Here the idea of representing “commutative” rules by way of mutually exclusive rule clusters is provided. But nofurther optimizations are applied, and hence no large gain in parallelism can be expected PARULEL’s execution is intended to be optimized by way of copy-and-constraining of rules ns2 project in Yukon Territory distributed to different processing sites. Optimizations may also be applied according to rule interdependence analysis as described in.
