|
> First of all , are you using the same kernel version on each machine ?
|
|
The 'same-kernel' refers to the version. You can build different kernel
|
|
images of the same source version to meet the hardware/software needs of a
|
|
given node.
|
|
However you wil need toe make sure that when you install openMosix
|
|
on your cluster, all your machines should have the openmosix-x.x.x-y
|
|
kernel installed, in contrast to having one machine running
|
|
openmosix-x.x.z-x, another running openmosix-x.x.x-y, another running
|
|
openmosix x.x.x-z, and so on and so forth
|
|
</P
|
|
><P
|
|
> When you run mosmon, press t to see the total of machines running. Does
|
|
it warn you that mosix is not running?</P
|
|
><P
|
|
> If yes, then make sure your machine's ip is included in /etc/mosix.map
|
|
(don't use 127.0.0.1 - if your machine's ip is such, then you probably
|
|
have problems with your dhcp server/nameserver). If it does not tell you
|
|
that mosix is not running, see what machines show up. Do you see only your
|
|
machine?</P
|
|
><P
|
|
> If yes, then your machine is most likely running a firewall and is not
|
|
letting openmosix through.</P
|
|
><P
|
|
> If not, then the problem is most likely with the machine that doesn't show
|
|
up.
|
|
|
|
Also: Do you have two nic cards on a node? then you have to edit the
|
|
/etc/hosts file to have a line that has the following format

need to set up a routing table, which is a whole different subject. </P

you use the 'Support clusters with a complex network topology' option you

'Maximum network-topology complexity support' on each machine.
