Issues with Orphan Computations in Distributed Computing Systems
E Shamsudeen., V. Sundaram · 2013
In distributed systems, the orphan computations [1] [2] make problems like data inconsistency and wastage of computer resources ’ usage time. The inconsistency [3][4] of data is a big concern among the users of the distributed systems. Here in this paper, the issues of orphans have been discussed and a case study that we face in our day to day life. The case study actually reveals how a common man gets affected by an orphan computation. The orphan may occur due to abort process, failure node or a failure of communication link between the client and server which participate in the RPC [5][6][7][8]. It is also discussed the situation of deadlock which is caused by orphan computations. The deadlock [9] [10] [11] situation actually locks the resources of the system by unwanted processes and hence affects the overall system throughput.
