Comments on "transparent user-level process checkpoint and restore for migration" by Bozyigit and Wasiq

The simple checkpointing and migration system for UNIX processes as described in the article of Bozyigit and Wasiq [1] can be improved in two ways: First by a technique to checkpoint and migrate applications without the need to recompile them and second by an alternative approach to precisely locate all the data segments of a process that need to be checkpointed. We fully acknowledge the difficulty to do checkpointing or even portable checkpointing for the general case of processes and do not claim to solve the many remaining problems with the simplistic checkpointing and migration approaches presented in the earlier article. Still we are aware of many systems and applications where a simple solution is extremely helpful once it also works with binaries.
