Dear All, 

 in my opinion a first step could be to parallelize the
SparseMatrixVector products. 

On the other hand it does not make sense
in my opinion to parallelize the operators over the dense matrices and
vectors since this are used (at least by me) for small matrices (say
10*10) and within parallel regions. 

greetings to everone

honnestly, ublas needs to be transformed a little bit. I had a look at
how Eigen is doing all the vector/parallel/multicore things and we need
to make some change into the code base before doing that.
