-         <strong>Faster linear algebra:</strong>
-        The linear algebra implementation in
-         <acronym>deal.II</acronym> is quite fast, but only compared
-         to other C/C++ implementations. We know that Fortran
-         compilers can do a much better job in optimizing the tight
-         inner loops of matrix-vector operations. We plan to try
-         interfaces from C to Fortran for that purpose.

+        On the other hand, we have made some initial experiments with
+        interfacing to BLAS routines on SUN, but it turned out that
+        our own implementation of the routines we tried was faster
+        than the ones in the vendor BLAS. Nevertheless, interfacing
+        to LAPACK or other libraries implementing high level
+        algorithms would be interesting.
