SMP Prob with Beowulf

[Heyman]

Hey guys,<br>
<br>
I am trying to cluster two computers, One a 333 and the other a 133. The 133 is the main server and I have got the /home and the /usr/local files shared by NFS.<br>
<br>
I have been reading the Beowulf HOW-TO and they say that the main server must have a RS access without a password. <br>
<br>
I have already created a file named hosts.equiv on the client computer that has the name of the main server in it like this<br>
<br>
<br>
fubar1<br>
<br>
<br>
Do I need the domain name after it? What else do I need to prove that it is using the two processors? I have come up empty reading the Beowulf HOW TO 10x at least.<br>
<br>

No, you don't need the domain name, but you have to be sure that the name service is working correctly. Try for example:<br>
ping fubar1<br>
from the client computer and see if it works.<br>
Then try to connect to fubar1 using rsh (but this should only work as normal user, not as root!).<br>
<br>
You can see what's running on the processors with standard utilities like ps and top.<br>

Do I have to install ssh on my Linux server? don't see it anywhere. I can run a rsh as a regular usr.<br>
<br>
When I do top I don't see anything that is showing two processors.<br>
<br>
The HOW TO says that I have to have the Server to be able to access the client through ssc without a password?<br>
