Title: Limit bitcoin to only use 2 CPUs under linux Post by: Flow on February 12, 2011, 10:36:57 PM I see this option in the GUI, but could not found the corresponding line in the command options nor the bitcoin.conf. I would like to run bitcoin on my server, which has no GUI available.

I would like to run bitcoin on my server, which has no GUI available. Flow I think you can do that on a OS level. For instance, running "htop" you can press 'a' to set CPU affinity. Title: Re: Limit bitcoin to only use 2 CPUs under linux Post by: Flow on February 12, 2011, 11:03:52 PM Thanks. But I prefer a persistent option, because the binary will still spawn 4 miner threads, when I want only 2.
Just wondering that there is a option in the GUI, which is not represented anywhere else. :-( Title: Re: Limit bitcoin to only use 2 CPUs under linux Post by: mail2345 on February 12, 2011, 11:38:03 PM I suggest writing a shell script that starts bitcoind and sets affinity.
EDIT: Or use an external miner, jgarzik's CPU miner has a thread setting.

Bitcoin will store the number of threads to run in your wallet and remember it across runs.

Bitcoin will store the number of threads to run in your wallet and remember it across runs. How do I issue the RPC from command line?Edit: Found it. Just set the user name and password in bitcoind.conf and run bitcoind with the given RPC command. Thanks all!

Bitcoin acts as its own RPC client when it's given any parameters that don't start with a dash. |
