Becouse of simplifying of job planning, the number of available properties has been reduced (both @arien and @wagap planning environments) -- those which exist on all machines, or almost are not being used:
linux, x86_64, nfs4, em64t, x86, *core, nodecpus*, nehalem/opteron/, noautoresv, xen, ...

Cgroups (control groups) is a Linux kernel feature to limit, police and account the resource usage (memory, CPU,...) of a job.
If you know that your job exceeds the number of allocated RAM or CPU cores, and these can not be reduced directly in the application, you can use parameter -W cgroup=true, eg .:
qsub -W cgroup=true -l nodes=1:ppn=4 -l mem=1gb ...
Cgroups replaced the previously recommended nodecpus*#excl -- as far as nodecpus* property has been canceled recently.
Please note:
To simplify planning possibilities in @wagap planning environment, there were reduced number of queues available. The time queues q_2h, q_4h, q_1d, q_2d, q_4d, q_1w, q_2w, q_2w_plus were removed. All jobs should be submitted to default or special queues.
Please use always the walltime parameter, for example.
-l walltime=2h, -l walltime=3d30m,...

Actual list of nodes with OS Debian 8 (debian8 property): http://metavo.metacentrum.cz/pbsmon2/props#debian8
If you experience any problem with libraries or applications compatibility, please, report it to meta@cesnet.cz.
To avoid running jobs on OS Debian 8 nodes:
-l nodes=1:ppn=4:^debian8 -- the job will not be scheduled to nodes with debian8 property or -l nodes=1:ppn=4:debian7 -- the job will be scheduled to nodes with debian7 property
OS of special machines available in special queues may differ, e.g. urga, ungu (uv@wagap-pro) and phi (phi@wagap-pro) are running on CentOS 7.
