Re: [Condor-users] Adding private network nodes to condor

Hi Senthil,
You don't need a separate pool per network. As long as they can route to eachother (which is a prerequisite for operation anyway) then they can all sit in the same pool. We have different pools for different subnets in various networks, but this is because those pools (and subnets) each belong to different groups/departments, who want to control their own resources while cooperating via flocking. I.e. it's a policy thing, as opposed to a technical one.
If you *do* set up flocking, then there's no "main condor pool" as such, as functionally all pools are equals. It's then up to you as to which submit nodes, from which pools, you allow to flock to which other pools. This is all in the manual but give me a shout if you'd like further discussion. 

Cheers,
Mark

Hi Mark,
Thanks for the Info.

I guess you are suggesting setting up individual condor pool for each private network and from the main condor pool, flocking the jobs to other private network condor pool right?

I was wondering is it possible to do with out setting up individual condor pool.

Suppose if we setup flocked pools, does the main condor pool will list all the machines form the all the pool, (i.e) the addition of nodes from flocked pools.

Thanks,
Senthil

Hi Senthil,

What you envisage should certainly be possible; we use a very similar
model here. In our case we have a number of flocked pools, with some
machines running only private IP addresses and others running both
public and private ones. However, Condor is forced to operate over the
private IP addresses *only*. Now, does your head node also have a
private address? It doesn't sound like it from your post, so I'm not
sure what you hope to achieve by setting BIND_ALL_INTERFACES. May I
suggest that you give the head node a private IP address too (it could
be a virtual interface; it doesn't have to have an extra NIC). Let's say
that this private IP address is 172.24.116.14. Then in your head node's
configuration you'd need:

CONDOR_HOST = head-hostname.my.private.domain
FULL_HOSTNAME = head-hostname.my.private.domain
NETWORK_INTERFACE = 172.24.116.14

All your other nodes don't need to nominate a NETWORK_INTERFACE, since
they only have the one. They just need to make sure to set CONDOR_HOST
to the same as above. Your pool should now work entirely via the private
IP addresses. Note that the head node also has a DNS entry in the domain
spanned by the private IP range.

Cheers,
Mark

Hi,

I am trying to add a cluster of machines (with the head node has
public IP address and accessible to public, other nodes are private
and can't be accessible to public) to the existing Condor pool.

I installed condor on head node and private nodes, and I added this in
head node condor_config file

BIND_ALL_INTERFACES = TRUE

But still I couldn't see those private nodes on Condor pool.

How to make those private nodes also part of Condor pool is there any
better solution to make use of ideal cycles of those private nodes.

Thanks,

Senthil
