New Revision: 22710

   seismo/3D/SPECFEM3D_GLOBE/branches/SPECFEM3D_GLOBE_SUNFLOWER/src/compute_optimized_dumping_undo_att/compute_optimized_dumping_undo_att.f90

Log:
switched from 90% or 92% to 85% because the system apparently needs more than 8% of the memory of a node for itself (at least on some machines)
