[HTCondor-users] Enable Job Router always

[Asvija B <asvijab@xxxxxxx>]

Hello everyone,

I am testing the Job Router functionality to setup a test bed of 
distributed infrastructure.

Following is my setup:

Machine A (in a Condor pool X)Â is to act as a submit node.

Machine B (in a different condor pool Y)Â is to act as a cluster head 
node. Condor is installed only on the head node. It gets integrated 
with SLURM batch submission for executing jobs on other worker nodes.

The job submitted from A reaches B by flocking.ÂÂ Once it reaches B, I 
want the job to be routed as a batch job to be submitted to SLURM. I 
have created the corresponding Job router in B and is active.

Now here's the problem:Â Since the job submitted at A has to flock to B, 
the machine B should report as having atleast 1 CPU available. 
Otherwise the job cannot get flocked from A to B as condor does not find 
a match.ÂÂÂ However when I start the machine B with having 1 CPU 
available, the flocked job from A will directly execute on the machine B 
without going to the Job Router.

How do I prevent this default behaviour and force the flocked jobs on B 
to go through the Job Router always ?

Is there any other better mechanism for accomplishing the kind of setup 
? I know about the OSG middleware with Condor-CE element. However my 
constraint is that I have to use Kerberos authentication and not rely on 
using GSI certificates.


Thanks and regards,

Asvija
