Dear Matt,

I just update the code. Greatly improved for the new one. For the bulk
water, now it has the nearly same speed as verion of Jan. 10. Then I test a
more large system, which includes surface. The speed is quite greatly
improved, for one OT step,

the quite new one is 7.45 s
the one Jan. 10 is 7.22 s
the version this morning is 8.05 s

The RS informations are as follows:

The quite new one:
