linux-2.6.11  (linux kernel vainilla)

 

Complete transparency	Binary Independent: no need to modify, re-compile, or re-link the application source code or object code
High efficiency	Minimal degradation of application performance (less than 10% checkpointing once a minute)
High controlability	Checkpointing behavior dynamically modificable during the run-time of the application such as the checkpoint interval through the /proc pseudo file system
High responsiveness	Extremely low latency in checkpoint initiation (3.5 microseconds to wake up the kernel thread)
Kernel level	Implemented as a Linux kernel module and a small patch for the 2.6.11 vanilla linux kernel
Incremental checkpointing	Only the memory modified from the last checkpoint is saved to stable storage
