[CHiPPS] About The Index of AlpsTreeNode when parallel

[化高峰]

Dear Professors,
        I want to get the index of TreeNode when solving the BIP,
        and I have test on a single computer,
        the tree node index is form zero to a certain number.

        But when I do the same thing on a parallel cluster, I am puzzled.
        The index of the first few tree nodes is already so large, such as
1695381798.
        I don't know why.
        Is this program to be so? If it is this, how do you determine the
index?

May You Best Wishes!
