Hi:
I am a door man use openais, I have build a cluster by 2 machine and
Fedora 2 OS , openais-0.80.tar.gz.
I used epckpt checkpointing mechanism years ago, and I do not know how
the ckpt in openais works, can
you tell me? I got 2 questions:
(1) what different between the epckpt and ckpt of openais?
(2) for example:
I run a infinite loop test program, which just show "hello
openais" endless.
if I use epckpt, i use command to generate the checkpoint of this
application:
# epckpt 'my_application_PID'
then I use command to restart my application from the breakpoint:
# restart 'my_application_checkpointing_name'
now, how can I use openais' ckpt to generate my application's
checkpoint file? and how can I restart my application from
where my checkpoint file recorded?
wait for your answer, thank you very much!
