Hi Sebastian,

I would solve this within the worker, which takes the number of the
superstep to create
a snapshot in an individual subdirectory to store a snapshot of the graph
which consists of
all individual partitions. Finally you just merge all partition files to
one graph representation.
It is not the same thing like using an OutpuFormat, I think. The
subdirectorys should be created
at the beginn of the super step before the workers start processing the
I did not implement this until now, but I work on the same or even a
comparable requirement.

Best wishes
