I'm running Precice 64-bit on Intel Core i5 750 on a Asus P755D motherboard.
I'm wondering how Ubuntu utilizes my CPU. Reason for this is, that whenever I'm running something which requires a bit of calculating power, it seems that core 0 (or the first core, if you prefer it) takes all the load, whereas the other 3 stays pretty much idle (2-8 %).
Is this normal? Also, I experience a bit of thrashing - which shouldn't occur, as I have 12GiB RAM installed, and a swap partition at 4GiB.
Again, is this normal, and if it isn't, how to fix?
All inputs are appreciated=)
PS: Command TOP, and 1 pressed, returns all four cores.
