[Beowulf] Building new cluster - estimate

[Ivan Oleynik]

Joshua,

Thanks for your response.

I may be wrong but Barcelona at 2.3GHz is being offered at the same price as
> Harpertown at 2.8GHz.

Yes, both opteron 2356 and Xeon E5440 are comparable in pricing (~ $700),
but it is 0.5 GHz difference!

I am going to run some tests, but our previous experience with 2.0GHz
Barcelona was not very encouraging.

Is this price with fully loaded unit (both cpu chips and decent amount of
memory present)? I would like to get the link to the source of info, if
available.

Thanks,

Ivan
