Step 4, every computer is ranked up to the second keyword offset distance under the keyword of corresponding No. CMP, obtains
Corresponding second serial number of the first index information data to after sequence.
Step 5, stores after the completion of every sorting by computer to the geological data after sequence.For example computer three is complete
Into after sequence, the second serial number after according to sequence is read original geological data by the computer, and geological data is put into
In the relief area of internal memory；If the geological data after sequence is continuous（It should be understood that the seriality of the geological data after sequence
It is equal to the seriality of the first index information after sequence）, just carry out multiple tracks reading, i.e., once read multiple tracks earthquake number
According to, if the geological data after sequence is not continuous, single track is read, i.e., once read one geological data.Other calculating
Machine is put into the geological data after sequence in the relief area of respective internal memory.
Step 6, all computers complete the geological data in respective relief area to be stored in into same storage after sequence
In file.Further, the geological data after every sorting by computer need to be stored in the relative position of storage file.Relative position
