A couple of comments that may be relevant:<br>
<br>
a) I'd really like to see evaluation of what we have, at scale, before
starting reimplementation of anything. (Have I mentioned that we need
to be showing routine use at scale if we are to justify continuation of
this project? An important step would seem to be to try running with
what we have.)<br>
<br>
b) The CEDPS guys are hard at work on storage management solutions
(MOPS is the keyword). I think we should be thinking about whether/how
this has a role to play in the future.<br>

changing the way things work, and we do that because we can.

there may be, but I don't know of one).

<pre wrap="">I think the reimplementation argument is not universally valid. One must
consider costs vs. benefits.

stage data in and out.
It seems fairly seriously worth considering using that, rather than
re-implementing stuff from ground up.
