Depends on the size of your memory, but a vector with a dimension of several 
million and SPARSE matrices with millions of rows AND columns (but few non-
zero entries) should be possible.  Of course, dense matrices with one 
million rows and columns need too much memory.

Not yet, but if you use dense matrices and vectors only, many operations can 
be done by cblas routines and should be as fast.
