[Lapack] Diagonally dominant linear solvers


did you consider an introduction of diagonally dominant functionality in 
LAPACK? That is, A=L*U (general) and A=L*D*L' (symmetric) with no pivoting.

I observe a growing interest to tridiagonal solver with no pivoting, in 
particular. In case of this solver the speed-up is dramatic - up to times - 
when using no pivoting. ScaLAPACK has already have it in for some reason - I 
mean p*dttrf/p*dttrs. I think it's worth while having it in LAPACK too.
