7    o pkg/seaice:
8      modify lsr-algorithm so that it vectorizes AND converges by using a
9      "zebra" method: split vector loop into two with step size 2; this
10      solves a general convergence problem for the JFNK solver on a vector
11      computer. It has the potential to even improve convergence for
12      non-vector machines, but it does change the results so it is turned
13      off by default. To turn on define CPP-flags SEAICE_VECTORIZE_LSR and
14      SEAICE_VECTORIZE_LSR_ZEBRA in SEAICE_OPTIONS.h
