For example, will DAXPY give essential speedup (percent of peak 
performance) for N=10 or 100 for example (for matrix and vector), and 
will DGEMM give high performance for meduim sizes of matrices - or 
we'll need large N values - for example, 1000, 10000 etc ?

What is about gather/scatter/etc for vector processing, the compilers 
for Cray T90/C90 ... Cray 1, NEC SX-6/5/4... performs, I beleive, all 
the necessary things.
