RE: [Condor-users] Condor job submission delayed

["Ian Chesal" <ICHESAL@xxxxxxxxxx>]

I have one client (Windows XP) for running jobs, one master (Linux, RH9) for control and one machine for submitting jobs from (Windows XP) and I'm seeing this long delay as well so I'm not thinking it's a load issue. Hopefully one of the condor team members has some insight into the issue...

Hi,

 Funny I was just going to post about this same problem. I have the same 
setup as Marc Saric described and I have the same problem as he 
described. Mainly, sometimes it takes a long time for the pool controler 
to send out a new job to a CPU that has recently finished.I see this 
often in my dual processor machines as well.

I have windows processing nodes and a linux master controller. I do have 
lots of cluster based node submissions all being submitted by my pool 
master. I wonder if this is the problem..The fact that the pool master 
is also the one that submits the jobs might be overloading the pool 
master somehow since it is also keeping track of all the jobs?? I wonder 
if i making so my client machines submit teh job will help clear up the 
problem..i'll try this today....
