Default Strange process eating up CPU time

Hello,

I'm running a 4-core system, Phenom 9600+, and even in a 32-bit Linux with the BIOS TLB workaround enabled, the thing is much faster than my 2.0 GHZ core2duo computer. Anyways, I was extremely impressed with the performance except when I run 4 simultaneous instances of Fluent, the fluent runs get distributed over 3 cores while another process called cortex.3.7.3 takes up and entire core by itself. Does anyone know what this is and if I can prevent it from hogging up so much cpu time?

Actually, I checked top just now and five instances of cortex.3.7.3 are running. Four of them take either 0-1% of the cpu time but it's the fifth that takes 100% of a cpu.

just kill the cortex from the PID ..they are useless and helps only to eat up CPU time it comes, if there was some kind of fatal close fr any simulation..and a ghost simulation (through cortex) starts running.. just eliminate it !!

Thanks, I'm thinking now that the giant cortex was a remnant of some previous crashed Fluent, since now that I've killed it , it hasn't returned.
