 To-do list for SPECFEM3D_SESAME, by Dimitri Komatitsch
 ------------------------------------------------------
 
+- serial domain decomposition is already a limitation in the case of regional seismology, because serial meshes can be very large. One option would be to switch to ParMetis or PT-Scotch, i.e., the parallel version of these domain decomposition packages. I know that PT-Scotch works great and is pretty fast. Another option is ZOLTAN from Sandia National Labs, but I do not know if it is serial or parallel.

 - update the manual before the first official release of version 2.0
 
 - For binary files (for instance Carl Tape's m16 model) we should use NETCDF to store them and read them back;
