In this paper, the authors have reviewed and discussed about the challenges, advantages and disadvantages of the parallel program, which occurs during the conversion of the sequential program into parallel program. The conversion of the existing sequential programs and algorithm into parallel have limitations like partitioning the task, sharing input and output data, dependencies of the output of one subtask to next subtask, synchronization of the output of the subprogram and shifting the subprogram from the failure processor to the active processor, communication among the processors, load balancing, etc. The parallel programming routines, libraries and management software for parallel programming have been implemented and these have several limitations and these are also discussed.
