[petsc-users] superlu_dist output

[Satish Balay]

from superlu_dist README

>>>>>>>>
      o -DPRNTlevel=[0,1,2,...]
      printing level to show solver's execution details. (default is 0)

      o -DDEBUGlevel=[0,1,2,...]
        diagnostic printing level for debugging purpose. (default is 0)
<<<<<

Presumably macports version of superlu_dist is built with these flags enabled.

cc:ing Sean to check if its an issue with macports superlu_dist package.

If you need to get rid of this output - you can build petsc from sources [with --download_superlu_dist]
