| The set of interface functions in TCE has been minimized due to a fact that by using multiple threads we could get rid of all non-blocking and asynchronous calls. Respectfully, much cleaner semantics and better optimized code has been obtained. Performance and functionality has not been jeopardized, since multiple threads provide more concurrency of execution. |
| Despite the fact that a higher abstraction level increases portability, a programmer may want to specify a particular machine to carry out the computation or impose a specific method of IPC for efficiency reasons. Those alternative operations are implemented as additional set of operators on communication objects. |
