....which processes a high level description of a computational task provided by a user and converts it into a set of facts and rules. Unfortunately, these scheduling algorithms for heterogeneous systems are non real time, which are not suitable for scheduling the tasks with timing constraints. In [15] we have investigated a real time and fault tolerant scheduling algorithm for heterogeneous systems, however, it is assumed that the real time tasks are independent with one another. For the algorithm to be of more practical value, task precedence constraints need to be taken into account for ....

....are main issues. Hence, if a real time collaborative editor is to be effectively used over the Internet, the system should tolerant the client and link failures, for the quality of the Internet are unpredictable [16] There are two main approaches to improving the fault tolerance: replication [6][13] and persistence [17] Components are replicated to make the systems faulttolerant by ensuring that all replicates process the same messages in the same order. If any one of them fails, others will still be able to continue. Persistence based solutions rely on checkpointing, which can recover the ....

To improve the dependability of the server in the runtime environment, especially in the Internet environment, the finish run join crsah recover checkpoint Fig.1 Diagram state for client sites 3 primary backup fault tolerant technique, which is a useful approach [13], is employed in server. Two server sites are linked via Internet or LAN, one serves as the primary and another is used for backup purpose to tolerant the single server failure. The backup server also maintains the remote final state of the system but it has no responsibility to propagate the ....
