Re: [Condor-users] howto avoid that a job is being evicted

[Harald van Pee <pee@xxxxxxxxxxxxxxxxx>]

Many thanks for this answer. This would help me much.
But I have one problem with rank.

- I use more virtuell machines than I have cpu's (this is because I want that 
all users get cpu power instantly, I will add as much cpu's as possible so 
there will be not more than 2 jobs per cpu)
-  I use default_rank to use free machines first (higher rank for vm1) 

now the question:
can I use the default_rank and a constant rank at the same time?
I use one configuration file (not shared) which is the same on each machine, 
in this I use the 
default_rank
can I use know a rank=0 statement in the local configuration file at the same 
time? 

My problem is: if I use 
PREEMPTION_REQUIREMENTS=FALSE
is then the default_rank still used?
If I understand it correct rank=0 ist the default. Therefore if 
PREEMPTION_REQUIREMENTS=FALSE
and default_rank can be used at the same time my problem would be solved?
