cores limitations using affinity

In our cluster, we are very often impacted by jobs under reserving cpus (using -n option of bsub). for ex, we have a user group using a GUI for days. When the user close the GUI, it fires thousands of tar/bzip2 -9 to compress log files, making exec_host unresponsive for 10/15 minutes. To limit cpu usage to the reserved number of slots, or a reasonable number of cores, we tried to use the affinity statement: it works but we cannot specify more cores than the number of cores available in the server. for ex, for a server having 40 cores, when specifying 8 cores per jobs, we cannot start more than 5 jobs for 120 slots avail on the servers (3 slots per core). we also impacted by many GUI vendor tools that trying to use the max available cores on a server ignoring slots reserved in LSF. For servers shared by hundreds of peoples, it's very impactful. Is it possible to change this behavior by allowing cores shared by jobs ? Also, to improve this new behavior, allow load balancing between cores ?
