I meant moderately sized non-sparse LP problems.
If you have lots of memory and several processors
that can be a big advantage. For some reason
the current glpk performs better on a p4, which was
a big surprise.

If i will write a
gsl_solve_LP(gsl_matrix *A, gsl_vector *b, gsl_vector *c)
function for { Ax>b, min(cx) } LP problem, is it really 
necessary to reallocate and refill A in a lpx_* way ?
