On Linux 3.11.0-13-generic running on top of a dual socket Xeon X5650 hexa core board,
htop shows different kworker threads. Sorted by names (I tweaked the result I am showing here a little bit to have the threads on core 2 before the ones on core 10), here is the result:
kworker/0:0H kworker/0:1 kworker/0:2 kworker/1:0 kworker/1:0H kworker/1:1 kworker/2:0 kworker/2:0H kworker/2:1 ..... kworker/11:0 kworker/11:0H kworker/11:1 kworker/u48:0 kworker/u49:4 kworker/u49:5 kworker/u50:1 kworker/u50:2 .......
The threads whose names start with a number are pinned to the core with the same number. So the first number is the core running the thread and I am wondering what the symbol after
1) is for these threads?
I am also wondering what is the meaning of the
I have only a vague knowledge of what kworker threads do: they handle asynchronous events caused by system calls performing I/O. Are they documented somewhere?
