Some computing applications are heavy on processor cache and those will
perform well on SGI computers. However, for most crystallographic computing
the Intel/AMD will do just fine. AMD will outperform Intel concerning
flooting point calculations (something you should consider).

Check out the following page:

If you plan to buy dual processor machines, you will need very good (!)
cooling. Single processor machines will do just fine but you should really
invest into a gigabit channel network, otherwise the scaling will be poor.

Hi,

For CCP4 computing and other crystallographic processing.
Would you prefer a big number-crunching server (SGI origin300 type) or a
collection of high-end PC's running linux (separate or as a beowulf-type
machine), with perhaps some money left for a serious party.

In other words: what would be your recommended system(s)?


Thanks,


Klaas
