Sounds like you have it John. As a side note, rtai looks for that idle cpu and uses it for all the realtime stuff. But because of the isolcpus, it is so isolated that top, htop, gkrellm etc, cannot access it to see how busy it is so it always _looks_ idle. But it isn't idle when linuxcnc is running. > ------------------------------------------------------------------------ > ------ Live Security Virtual Conference > Exclusive live event will cover all the ways today's security and > threat landscape has changed and how IT managers can respond. > Discussions will include endpoint security, mobile security and the > latest in malware threats. > http://www.accelacomm.com/jaw/sfrnl04242012/114/50122263/ > _______________________________________________ > Emc-users mailing list > Emc-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-users Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
