Re: [HTCondor-users] Why all jobs are sent to slots in the same machine?

[David Hentchel <dhentchel@xxxxxxxxx>]

I have a similar, but different problem its solution might be similar to this one.

To summarize, I am testing high-performance distributed DBMS servers in the Parallel universe with up to 100 concurrent, closely-integrated processes running on as many hosts.  I only ever want to allow 1 job running on a machine, but since these are 8 core systems, I currently see 8 Slots for each host.  I am using the machine_count property in the job classad to specify the number of different hosts to launch concurrently.

Is there a "best" way to set up machine class ads so that only one of these jobs can be running on any host?  Perhaps a way to set the number of slots per host to 1?  (I am a new Condor user).

regards,

dave

Is there a way to do it via config files? I.e. let the sysadmin set it
once and for all rather than trying to get each individual user to
modify their submit files?
