Thanks Todd very much for help. I killed all condor processes, then  
changed the owner and group for those folders at condor, and restarted  
condor_master.

Everything is running condor_master and condor_startd under user  
condor. And condor_procd under user root. I hope it is ok.

Finally, I can see all cores available.

The HTcondor installed my profesor before. I have not speaking with  
him yet. But I do not think that he would use different than standard  
distro instalation.

One more time, thanks a lot to all condor users who helped me.

Rene
