Dear all,
I am currently configuring a small cluster on which I would like to run
mainly AMBER/NAMD/GROMACS.
The choice seems to be between the latest AMD Istanbul and Intel Nehalem
chips with infiniband interconnect (approx. 10 double CPU nodes). I am
not an expert in hardware so unfortunately I cannot give many other
details.
I would be curious about your thoughts on the NAMD performance on the 2
chips. Is there anything in particular that one should consider ? Would
there be any reason (except price) to go for slightly older chips?
Is there anything one should consider about the infiniband inter connect
? Could one replace the inifiniband with 10 Gbits ethernet ?
Thanks for your thoughts
Vlad
