[gentoo-cluster] Most stable kernel for mpich2 cluster?

Hi,

I build a cluster for Technological Institute of Athens, here, in Greece, with gentoo. My hardware is sixteen HP DL380 with 3.00GHz Xeon(do not laugh, I know that my cluster is too small for those you design and maintain). I read in gentoo hpc documentantion that I have to install the pure vanilla-sources but I have problem to decide the best version. 2.6.18.1 is out but I think that it' s not a good idea to install the latest kernel, so, I would like to tell me your opinion(eg, I think debian is using 2.6.8(too old!))	

Panos

I'm still a student of computers science in Athens, so, don't find my question silly plz :p

Hi,

I'd suggest asking this on the kernel.org maillists, Since i don't think LVS
clustering has many special requirements on the kernel.

Any new fresh kernel 1.6.18 might need a bunch of security/stability fixes,
But on the other hand , the 2.6.17 kerne should allready have received most
of those simple fixes, and shoud thus be stable.

Maybe if you need special patches (no-arp), that only support a fixed set of
kernels, then you need to look for a special kernel version, but that
depends on your patches.

I'm running a cluster of 6 dl360's (g1), so your's looks like a beast next
to mine :P

with regards
Jan

Panos,

	Any two, three machines connected together is a cluster ;) As for the kernel, IIRC, the "vanilla kernel" directive is only for people attempting to build an openmosix cluster (doesn't seem to be your case).

Hi

Sorry to hijack the thread but i have a quick question. Is the
recommendation to use a vanilla kernel and then patch openmosix onto it or
use the openmosix ebuild? I'm looking to use the 2.6 series to build a small
cluster (only 3 machines) and i would like to use a reasonably recent kernel
(I think stable vanilla is at 2.6.17.8 atm in portage which would be ideal).

Regards
Owen

Use caution with the 2.6.x series for OpenMosix the kernel is great  
but, the new tools are still very Alpha (2006-05-21 - Alpha openMosix  
2.6 Tools will remain for Developers only until released as Beta.
