Recommend: Do ASAP.
Q: Funding?
Other issues and concerns with actually implementing this approach:
- Rack space. Maybe power. Maybe cord lengths. What other issues?

Do all compute nodes: ~$18K every ~4 years.

~20 20amp UPS's ($900 each) required.
These Estimates are from simply back-of-the-envelope calculations.
If were to actually implement, there may be smarter ways to do this, but the total cost will likely not be lower. (
- In fact, costs may be higher, if sufficiently higher benefit doing it a different way, for example.

Compute node counts, for UPS pricing estimates. Does not include head node:

Cluster	Compute node count	Power strip equivalents (~8/strip MAX)	Cost estimate, every 4 years	Notes
Collum	8?	1	Sprin $900
Lancaster, with Crane (new)	12?	2	Funded by Crane $1.8K
Hoffmann	14?	2	$1.8K
Scheraga	92?		13	$11.7K See below chart for s4 tand-alone computational computers
Loring	6?	X	1	$900 Unique: Need to do ASAP
Abruna	6?	X	1	$900 Unique: Need to do ASAP
C4 Headnode: pilot Widom's 2 nodes there.	N/A	N/A	N/A	This CCB Community headnode pilot is provisioned on the margin. (Not funded by Widom.) has no compute nodes of its own.
