Actually, that's not true. The core is still there, and is still monitored by the normal tools. The only thing ISOLCPUS does is tell the Linux scheduler not to put any tasks on that CPU by default. Tasks can still set their processor affinity to that CPU if they like, and those tasks will still show up in tools such as top.
It is true, however, that the RT kernel on the EMC2 liveCD is not compiled for SMP, and therefore will not see more than one core (real cores or HT "phantom" cores). With an SMP kernel, the Atom 330 will look like a 4-core CPU, if HT is enabled. - Steve ------------------------------------------------------------------------------ This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
