Running on snap datasets about differential-dataflow HOT 2 CLOSED

Hi!

The most obvious thing that stands out is that the ~/Projects/Datasets/ is a directory structure I have on my laptop, and you may not have. It sounds like the program is having a hard time opening the filename provided, and if that file doesn't exist there things will break.

A second issue is that if you are using the github master (vs the version from crates.io) then it will want to use the GraphMap format.

https://github.com/frankmcsherry/differential-dataflow/blob/master/examples/cc.rs#L30

This is a binary layout that can be efficiently memmapped in. To get it in that format I'd swing by the graph_map repository which should be quick to build, and have a binary parse for which you can type

cargo run --release --bin parse -- path/to/WikiVote.txt path/to/binary_output

This should go and process the file and drop it in graph_map format, at which point you can run cc with path/to/binary_output.

Sorry for the confusion. The examples are a bit of a mix of "shows how DD works" and "might run for you with help", but aren't exactly freestanding analyses.

Thank you very much! It works now 💯
