Hi ALL
We are going to build a true Beowulf cluster for Numerical Simulation
of
Computational Fluid Dynamics (CFD) models at our university. My
question is
that what is the best choice for us out of the following choices
about
processors for a given fixed/specific amount/budget:
1.
One processor at each of the compute nodes
2.
Two processors (on one mother board) at each of the compute nodes
3.
Two Processors (each one dual-core processor) (total 4 cores on
the
board) at each compute nodes.
4.
four processor (on one mother board) at each of the compute nodes.
Initially, we are deciding to use Gigabit ehternet switch and 1GB of
RAM at
each node.
I've heard many times that memory throughput is extremally important
in CFD and that using of 1 cpu/1 core per node (or 2 single cores
Opteron having independed memory channels) is in some cases better
than any sharing of memory bus(es).

Please guide me that how much parallel programming will differ for
the above
four choices of processing nodes.
with best regards:
Amjad Ali.
