Re: is there a linux-image-2.6.17-x-amd64-k8?
Specifically, I should add, we have detected a bug in mpqc2.31, unable - with
large complex molecules - to build correctly the hessian in internal
coordinates, reading cartesian coordinates. We turned to cartesian
coordinates throughout, which is less efficicient.
Now I wonder whether instead of a bug in mpqc it could be a problem of the
kernel (just a naive doubt, possibly devoid of any scientific ground). I was
using 2.6.15.-1 k8 smp.
No major difference to all purposes? In particular, using the system for
computation (mpqc2.3.1) without X, aimed at the highest possible floating
point.
I am just reinstalling amd64 on dual opteron (hope the old net installer - 19
July - works; the newest does not, as I have reported. Therefore, I am
interested in replacing the generic kernel that has been just installed.
