     15= Feature List
     16* Multi level checkpointing
     17    * Node local
     18        * single checkpoint per node (level 1)
     19        * Buddy checkpoints (level 2)
     20        * Encoding checkpoints tolerating failures of half of the nodes/processes (level 3)
     21    * checkpoints on parallel file system (level 4)
     22- Differential checkpointing (available for posix/fti-ff level 4).
     23  Differential checkpointing means the differential update of a
     24  CP file. Unchanged application data compared to the last checkpoint
     25  will not be updated and thus saves I/O time.
     26- Incremental checkpointing. Incremental checkpointing means the incremental completion
     27  of a CP file. This technique serves primarily to avoid overhead
     28  caused by oversaturated network channels. It may also be used to overlap
     29  computation and checkpoint I/O
     30- Single file checkpoint on the PFS using HDF5 or MPI-IO
     31- Asynchronous post-processing of higher level checkpoints
