I'm about to buy a small cluster of machines for running MD calculations
on. I intend (at this stage) to put linux on them.
I was wondering if people had any benchmark data to compare the pentium IV
machines to pentium IIIs etc? My systems of interest are quite large
(lipid/ion channel systems). A colleague uses p4's with RDRAM for
heavy-duty fluids calculation and if I don't need too much RAM per machine,
they are quite cheap now. Is 128MB enough?
Or whether I should go with a smaller number of dual processor machines, or
more single processor machines?
Also, thoughts on various flavours of mpi and linux would be welcome. I
gather from various discussions here that LAM seems to be less problematic
Any thoughts welcome!
