If you're not planning on running parallel jobs I would go for the
higher clock speed. If you're running parallel, well, I am not sure.

Hello,
We are in the process of building a cluster on which GROMACS will be
the main computational engine and I have a question about performance.
We are not yet decided what to buy (we can not test them in advance).
Which configuration do you think will be better:
- 8 servers with 2 x dual core opterons 2220 (2,8 GHz) = 32 cores
or
- 4 servers with 2 x quad core Xeons 5335 (2.0 GHz) = 32 cores
Both configurations with Infiniband Interconnect. My opinion is that
the Xeon based should be the choice because of its 128 sse bus, but I
don't know what to say about the clock speed difference.
Thank you,
Andrei
