Question about the modification of cpucorestotal?

Dear all,

My question is that I can't change the cpucorestotal. The maxium is 8, my laptop has 8 cores, so it's ok. But when I chose the HPCC, no matter how many cores a queue contains, the maxium is still 8, and I can only use 1 queue. The HPCC manager change the following entries from 8 to 12. But there's no change, the maxium is still 8, and can not use more than 1 queue. No matter I start the job from Windows client or submit job by PBS file on HPCC. Could you give me some suggestions?

./etc/Gateway/root_default/dsd/conf/gw-info.sbd:cpucorestotal=8

./etc/Gateway/root_default/dsd/conf/gw-info.sbd.srv.rw:cpucorestotal=8

./etc/Gateway/root_default/dsd/conf/gwparams.cfg:gw_cpucorestotal=8

Thanks,

Xiaoquan Sun.
