Subject: CPU Balancing
Ehlo everyone, I have a Dell Server with 2 Xeon CPU's running RH AS 3.0 and when I go to top I see 4 cpu's, while I know this is caused by the Hyper threading technology, I don't know why the processes are assigned to only one cpu at the time. Is it possible to a process to use all cpu power available to finish its task faster?
Only if the applications themselves are hyperthreading aware and/or written in a way that know how to handle multiple processors. Most apps are not. The advantage you still get is that the OS itself will try to split the load between the two CPUs (and virtual CPUs in hyperthreading cases).
With Intel finally abandoning the Ghz race and now claiming it's all about multi-core, multi-threading, etc, you should see more developers writing their apps and compiling them with hyperthreading and SMP in mind.
