It's my first experience of mining, is it normal that I have always thread 0?

I'm on my first experience with mining.
I installed minerd and am trying to mine PPCoins on bitparking, but while I'm mining I'm having always thread 0 in each line of output.
Like this

Is it normal? I also not able to see any stats change on my account on bitparking pool. It there any way to check whether I'm connected correctly?
Thank you in advance for any suggestion.

Yes. A lot of computer stuff start counting at 0, rather than 1. If you have 2 GPUs, they will be GPU0 and GPU1.

But what exactly "thread" means?

Thank you! I figured it out somehow, but was not able to find it on web :-/

Hello,

Code:

./minerd --help 
[...]
--threads N
(-t N) Number of miner threads (default: 1)
[...]

Per default it seems to only use one cpu core.
If you have for example a quadcore and you want all cores to work you can set --threads 4.
