Hi.

We have a small cluster here, and have installed and successfully run ADF on single processor 1 Ghz Athlon machines.

However, we have some dual Athlon boxes (1900+ MP processors) and ADF is unusable! The boxes are not set up to run as a massive parallel machine, nor am I trying to run ADF on more than a single processor (at this time). Running a single instance of ADF on the dual box, with no other big processes running, is painfully slow - a simple DIRAC calculation at the start can take up to a minute for a light element!

Obviously there is something seriously wrong with the setup of the dual box (other programs, such as Gaussian, run without problem).

Can anyone shed any light on this?

Cheers,
Tris.
