Dear all,

I have conducted a lot of experiments that have led me to conclude that
the checkpoint time of a parallel application of n processes with
aggregated memory size S is almost the double of the checkpoint time of
a sequential application with memory size S.
Is there any explanation to this?

Thanks.
