RE: [condor-users] Big pool one central manager?

["paul wilson" <p.b.wilson@xxxxxxxxx>]

We have 930 condor machines hooked up to one single manager/submit node.
We hope to scale up to harness the remaining 2000 machines, and we'll
see how it works using our current set up.

The pool's done over 105,000 hours work in the last 5 months.
The single queue has, on several occasions, contained 5000 jobs. 

We have an 'easy' network and deployment environment- all the computers
are centrally managed- the single point of access and submission works
for us.

There are new installations in the UK which will be larger than ours
with much more complex political and ownership issues. They will be
solving the problem using mulitple smaller pools and flocking.

Paul.

There are at least several pools in existence that are large than this
with a 
single central manager.  In fact, one of them is here at UW CS.  At the 
current moment, our pool has 930 VMs reporting to it.  There are larger
pools 
in the wild.

For large pools such as this, the central manager is typically not the 
bottleneck.
