At least for UGE, you will want to use the CPU set integration, which will assign the job to a cgroup that has one CPU per requested slot. Once you have cgroups enabled in the exec host OS, you can then set these options in sge_conf:
cgroup_path=/cgroup cpuset=1 You can use this mechanism to have the m_mem_free request enforced as well.
