 +===== Notes =====
 +
 +  * First make a page comparing CPU vs GPU usage which may influence future purchase [[cluster:167|CPU vs GPU]]
 +  * $100k quote, 3to5 vendors, data points mid-2018
 +  * One node (or all) should have configured on it: amber, gromacs, laamps, namd, latest version
 +  * Nvidia latest version, optimal configs cpu:gpu ratios
 +    * Amber 1:1 (may be 1:2 in future releases) - amber certified GPU!
 +    * Gromacs 10:1 (could ramp up to claiming all resources per node)
 +    * Namd 13:1 (could ramp up to claiming all resources per node)
 +    * Lammps 2-4:1
 +  * 128g with enough CPU slots to take over ''hp12'': double ten core minimum
 +  * Anticipated target (also to manage heat exchange)
 +    * 2x10 Xeon CPU (~100gb left) with 2xgtx1080ti GPU (25gb memory required)
 +    * as many as fit budget but but no more than 15 rack wise
