Can any body please tell me how to know in HyperThreading is enabled in linux or not.
just cat /proc/cpuinfo , here if u see info abt 2 processors then it means that ht is enabled. also if it is notenabled then is there any command in linux through which I can enable hyper threading without having to shutdown no first you'll have to enable (if not already enabled) HT from bios , then u need a kernel with smp support. in ubuntu u can get a smp enabled kernel image by sudo apt-get install linux-686-smp google for the smp image file name for other distros or u can compile a vanilla kernel and make sure u select SMP support in menuconfig (CONFIG_SMP=y in .config) -- Thanks and Regards Vivek Kutal (विवेक) http://vivekkutal.blogspot.com "Debugging is twice as hard as writing the code in the first place.
