@fhueske We will propose three experiments based on your suggestions in a
Google Doc on Monday. Once we have fixed the setup we will prepare a Peel
bundle an run them on one of the clusters in the lab.
I would be also happy to promote Peel by leading a joint blog post for the
Peel website together with @ggevay and you if you are interested. I think that
the hash-table makes for a perfect use-case.
