Having looked at where you've placed the #pragma omp parallels, have
you tried enabling vectorization to see if the time spent in those
axpy-like operations could be improved?  A good SSE-ready optimizer
should nail those.

I may have misunderstood your "millions of differential equations"
statement.  Are you rather solving one problem with a million degrees
of freedom?
