Hitachi has added a larger problem sizes in programs mod1ac, mod2a, mod2b,
mod2d and, mod2f to show off the vector capability of the nodes for long 
vectors.
In mod2f something has gone wrong with the initialisation timings of the
FFTs, probably because of the timing resolution. As Hitachi did not 
officially comment on this, we can not be sure. The total timing seems OK.
