Many thanks. <br><br>I have a basic (dummy) question here...Does downloading external packages like blas,lapack, hypre with Petsc command make them usable for other codes as linked libraries or is just for use of Petsc?<br>

</div> We removed the interface to sparsekit a long time ago, because it wasn't very good.<br>

If you want to use ILUT you can use --download-hypre then run with -pc_type boomeramg -pc_hypre_type pilut<br>
<br>
See <a href="http://www.mcs.anl.gov/petsc/petsc-as/snapshots/petsc-dev/docs/manualpages/PC/PCHYPRE.html" target="_blank">http://www.mcs.anl.gov/petsc/petsc-as/snapshots/petsc-dev/docs/manualpages/PC/PCHYPRE.html</a> for more details and run the PETSc program with the above options and -help to see the various pilut options.<br>
