Detailed Description

Partition of a domain from a disk file containing, for each element, the processor number to which that element is assigned.

The file must contain an array in ArrOfInt format (number n of values followed by the values). The size of the array must equal the number of elements in the domain to be split, and each value indicates on which processor that element is to be placed.
