Those "nodes" I speak of are actually four nodes each - sorry if I
confused anyone there :)<br>

What I meant by "larger" in this case was faster cores, more RAM,
so everybody should be able to take full advantage of them.
They'll be the closest thing to (or maybe faster than) the machine
Lee's got in his office. Same processors, or very similar, I
think. So I'll do both - a $3100 node and another node like the
one we already have in Rack 2. Cool. Thanks guys.<br>

<div>For my needs, I think more cheap nodes is better than
fewer awesome nodes. Rack 2 has been great for most (or
all?) of the things I've wanted to do since it was put in.
I rarely use the larger nodes at all, partly because
others can make better use of them and partly because I've
had weird error when I try to use them.<br>
<br>
</div>
Of course, I'm mostly happy with the computing power we have
now, so if others want larger nodes, their voices should
probably take priority.<br>

buying more nodes for the cluster this year, should I
prioritize:<br>
<br>
(1) More cheap nodes like we currently have in rack 2 (I
could buy somewhere around 12 - 16 more of those nodes, or
maybe 4 if I go with option 2 as well)<br>
(2) Faster, more modern nodes with more RAM, but fewer of
them (4 of them, to be precise)<br>
<br>
I'm leaning towards (2), because:<br>
1. They will last longer<br>
2. We're almost out of space<br>
3. We don't have very many really fast, semi-modern
Intel nodes.<br>
<br>
I can buy 4 nodes that are kindof like dual-processor
six-core (so 12 cores total, shows up like 24 because they
each have two execution units) versions of compute-1-17
with 48GB of RAM each for a total of $3100 used on eBay...
or with 96GB of RAM each for $4600. Seems like a good plan
(we don't ever need quite that much RAM though, do we?).
Or I could buy a whole bunch more of what we've got in
rack 2, though I'd have to get rid of a couple of the rack
1 nodes, and I couldn't put them on UPS, which is maybe
OK, since the power problems seem to have been resolved.<br>
