[CP2K-user] cp2k on 10 GbE

[Mike Ruggiero]

Hello cp2k community - I have recently setup a small computing cluster, 
with 20-24 core server nodes linked via 10 GbE connections. While scaling 
on single nodes is as it should be (i.e., nearly linear), I get very 
little-to no scale up when performing multiple node simulations. After 
digging around, it seems that this is relatively well known for cp2k, but 
I'm curious if anyone has had any success on using cp2k over 10 GbE 
connections. Any advice would be greatly appreciated! 

Best,
Michael Ruggiero
