I installed all the packages in a mac machine. When I run " mpirun -np 4 
~/bin/cats3d.1 -mat_view_draw -draw_pause -1" under X11, I get some errors:
[0]PETSC ERROR: --------------------- Error Message 
[0]PETSC ERROR: Argument out of range!
[0]PETSC ERROR: ASCII matrix output not allowed for matrices with more than 
512 rows, us
e binary format instead!

 MatAssemblyEnd error          63


The matrix is  with more than 512 rows. How can I use the binary format?

Happy holiday,
