....the result is ready. Concurrent C and uC lack the future mechanism, however, it can be implemented in uC using a class which contains a semaphore to block the client, but retrieving the value of future is not simply possible. Some concurrent languages such as ACT [6] COOL [8] and CC [13] use the future variables as a useful concurrency feature. 5 Concurrent C As it was discussed earlier in this report, Concurrent C is the result of the integration of the concurrency features of Concurrent C and the data abstraction of C . Therefore Concurrent C is not an extension of ....

....such as locks, distributed read write semaphores, and signals. Being subject to its target language C and a conventional compiler, PANDA can hardly support more sophisticated synchronization paradigms that would require language extensions [Gehani and Roome 88, Nierstrasz and Papathomas 90, Saleh and Gautron 91] Global virtual address space Typical C applications follow the spirit of the C programming language in that they rely heavily on pointer references. This yields a rather impure object model due to the lack of encapsulation, but offers maximum efficiency. Restricting the use of pointers ....

....synchronization objects such as locks, semaphores, and signals. Being subject to its target language C and a conventional compiler, PANDA can hardly support more sophisticated synchronization paradigms that would require language extensions [Gehani and Roome 88, Nierstrasz and Papathomas 90, Saleh and Gautron 91] Because of user level thread implementation, synchronization operations are extremely fast; their overhead is determined by the cost of procedure calls. By applying the inlining mechanism of C these costs can be further reduced. The efficiency of synchronization primitives is the decisive ....

....allowing to adapt it to changing requirements. On the other hand, however, several mechanisms proposed to handle parallelism and concurrency control in the object oriented setting can be implemented only by introducing special language constructs [Gehani and Roome 88, Nierstrasz and Papathomas 90, Saleh and Gautron 91] thus, they are not applicable in this case.
