I will argue that there can be useful research work at exascale (which
is what I think the question is here).

For instance, the heart model Cardioid (which was a Gordon Bell
finalist this year) was able to model a single human heart at 0.1mm
resolution in *almost* real time on all of Sequoia with about 58%
efficiency (11+TF).

So if you wanted to simulate the effect of something over the period
of days, weeks or months you'll need to wait days, weeks or months.
Scaling that up means you could do a lot more testing in-silico.

To really make a new thread you also need to get rid of the
References: and In-reply-to: headers as well, otherwise it just shows
up in the same thread in any sensible MUA.. :-)
