2) whether the disk space value summation of determining the code file selected less than the task amount average, if, execution in step 3), otherwise execution in step 4);
Need to prove that the code file of selecting refers to select and do not finish all code files of grouping here from code collection, might be one, might be for a plurality of.
The code file of selecting represents that namely code file selects from code collection, namely no longer include this code file in the code collection.
Preferably, if select for the first time code file, directly according to the disk space value size of code file, determine that whether the disk space value summation of the code file selected is less than the task amount average.
If not for the first time select code file, then according to up-to-date definite difference and the disk space size of the up-to-date code file of selecting, determine that whether the disk space value summation of the code file selected is less than the task amount average.
3) according to the difference of task amount average with the disk space value summation of the code file of selecting, from current code set, select space disk value near the code file of this difference, and return step 2) whether redefine the disk space value summation of the code file of selecting less than the task amount average;
4) the current code file of selecting is formed one group of code file.
Need to prove, the current code file of selecting is formed one group of code file after, the current code file of selecting is finished grouping, no longer belongs to the code file of selecting.
After obtaining N-1 group code file, remaining code file in the code collection is formed one group of code file, thereby obtain N group code file.
Because the preceding N-1 that adopts aforesaid way to obtain organizes disk space value summation and the task amount average of code file and relatively approaches, therefore the disk space value summation of the code file that obtains of last group is also relatively near the task amount average, thereby more balancedly realized the task distribution.

In the residue code set, select second group:
Select maximal value earlier, be 6.4 this moment;
13.1-6.4=6.7, near 6.7 be 5.6;
The file of selecting 6.4 and 5.6 with 12 less than average 13.1, difference be 6.7-5.6=1.1 near 1.1 be 1.4, and 1.4+5.6+6.4=13.4 13.1, stop to select;
1.4, the code file of 5.6,6.4 correspondences is divided into one group, distributes to a statistical module
The code file of remaining 2.7,4.8,5.0 correspondences is divided into one group, distributes to a statistical module.
