Re: [Condor-users] Linux 3 kernel

[Hermann Fuchs <hermann.fuchs@xxxxxxxxxxxxxxxx>]

Hi

In fact condor 7.4 will work on linux machines with kernel 3.x.
However you will use all information concerning cpu usage, so no
suspension is possible.
If you adapt the configuration files accordingly,it will work though. We
did that until the new version 7.6.6 came out.

Mixing different condor versions worked fine in our pool as well.

Cheers,
Hermann
