Hello list,
We have been using BLCR for a little while to checkpoint applications, but
we ran into a certain one that BLCR could not checkpoint. DMTCP has been
able to checkpoint it and that is nice.
However, we are having an issue. This particular program writes to output
files regularly. Using the --interval option there is inevitably some time
after the checkpoint at which the program will write output to a file. When
we restart from the checkpoint, this same data will be written again to the
file. This was avoided in BLCR by using a flag to indicate that BLCR should
kill the job after checkpointing. I have had trouble finding such an option
in DMTCP. What is the best way to solve this issue in DMTCP?
