Concurrent programming is still challenging and difficult. “Since concurrency techniques have become indispensable for programmers who create highly available services and reactive applications, temporal dimensions of correctness introduced by concurrency, i.e., safety and liveness, are central concerns in any concurrent design and its implementation” [Lea 98]. And without expert guidance and concurrent design-pattern description, they’re expected to occasionally fail. Thus providing significant examples and paradigms for teaching good and correct style is of prime importance.

Learning concurrency paradigms is necessary but it is not sufficient. The choice of the run-time semantics must be known since it may introduce subtle design and programming errors. It is the aim of this paper to exemplify the importance of process queuing and awaking policies (whether processes are named threads or tasks) resulting from possible choices of the monitor concept implementation.

Definition Index entries are maintained by documentation developers in the Knowledge Warehouse [Ext.] (KW) in order to help users find information more easily by means of an index. Use Index entries created from the Knowledge Warehouse are now stored in SAPterm and can be changed there as well. Index entries can only be created in info object maintenance in the Knowledge Warehouse. For more information, see Creating Index Entries in the Terminology Database [Ext.]. You can, however, change index entries in SAPterm by selecting an index entry from the results list [Page 13] and choosing Maintain entry.
