Subject: [Patches] Steering checkpointing by wall time
Message-ID: <6ACB027F-E8B7-443F-BB2D-651B84D5F6FC@cct.lsu.edu>

I suggest to add a new parameter to CactusBase/IOUtil which  
checkpoints every so many wall clock hours.  This is often more  
convenient than choosing the checkpointing interval by iterations.
