(57) Abstract In order the job which is run by the computer program, for checkpoint to be done more frequently, furthermore they are two manners in order to partition to the small piece. At the beginning, parallel task one where q has early partition or starts input data set, p splits with multiple data sets, into partition due to a some combination (partitioning device/cutting device), of the partitioning element the instance of the component program on each one of partition, the set of the multiple output files, the data set to which each set is partitioned p of the data runs one or creates is considered. This invention new excessive partitioning is applied to this kind of task in order like below to create the task which is done. (1) the partitioning device the q n*p splits entry to partition the excessive partitioning device displacement vis-a-vis integer excessive partitioning coefficient n. (2) the component program serial n is run at execute phase, p of the component program instance is run at optional point in time. At each phase, each instance of the component program, reads one excessive partition of the input data, creates one partition of the output data. (3) n each one of execute phase being last, the system is stationary, it is possible to do checkpoint configuration. The 1st example in order to create the intermediate file which excessively is partitioned, using the known partitioning device program, the communication channel, and the cutting device program, explicitly excessively partitions the input data. The 2nd example dynamically excessively partitions the input data by arranging the component program in order to read the continual subset of the original input data continually.
