[HTCondor-users] adjust memory of slots according to free memory on machine

[Thomas Hartmann <thomas.hartmann@xxxxxxxx>]

hi,
i have the following problem: some machines in my condor pool are also 
used directly by individual users. i managed to write a policy that jobs 
only get submitted to those nodes when the machines are idle. jobs also 
get evicted when the user returns. so far so good.

the problem is that some users tend to leave open some programs that 
might consume a couple of GB of RAM. however, in my current 
configuration, condor uses all the physically available memory for the 
slot. thus, when the "owner" of the machine leaves the programs open 
(which is his/her good right to do so) and a job gets submitted that 
tries to use all of the machines RAM, the job fails with "out of memory".

is there any way that only the really available amount of RAM is 
allocated to the slots?

thanks and best wishes,
thomas
