I do a lot of internet marketing, and am a bit of a webmaster on the side. As a result, I have a couple of dozen Amazon t1.micro instances with very low CPU utilization that other people are paying me to keep running.

Since I'm already paying for the servers and CPU utilization is not metered, I'm looking for a linux cpuminer that I can use to more fully utilize the processing power at my disposal. It is important that this not overtax the CPU to the detriment of the webserver, though - are there any tools out there that will help me constrain resource utilization to under, say, 80% total across all processes?

I looked through the stickies, and it doesn't look like it will be an issue setting up the miners, I just need to be pointed in the right direction to learn how to keep it out of the way of the actual "work" being done on the systems.

I'm looking for a linux cpuminer

um .... ya.  you're a little late to the party.  cpu mining for bitcoins went out of vogue in 2010.

I doubt you will get enough bitcoins out of it to justify it with cpu mining.  Spend that time doing more of what you do best and you will make more money.  Buy BTC with that money instead.

I don't expect to make significant BTC doing it, I understand that you need at least a good GPU to mine anything significant - It's just that I have all of these instances, with no accompanying power bills to pay, sitting idle.

Guys... look. I understand I'm not going to make significant money with this. If I make .05 BTC / week, I'd be suprised.

It is bothering me that I'm paying for CPU time and not using it, when I could be using it to (trivially) be more involved in supporting Bitcoin. If I don't do it, it's going to bother the hell out of me.

You've already been recommended to mine something -other- than Bitcoins and sell them to idiots who think they are valuable.

You realize that is 25 cents a week?  If it causes ANY problems at all with your paid customers you blew it.

This is the best point in the thread.

I'm still playing with it, though, at least on my own VMs Smiley So far, I can keep bitcoind from overwhelming my CPU when downloading the blockchain by setting the process to a niceness of +19 - once that's done I'll see about keeping p2pool within acceptable limits.

if the micro runs at the same speed as the free trial instance then if you mine Litecoin you'll get about 0.05 LTC a day per instance, which at current market conversion of 0.001BTC is 0.0005 BTC. So 0.006 a day total for 12 machines?

It's cheaper just to get on dailybitcoins.org, and you may get some of their higher prizes. There is another similar one as well, but I can't remember what it is called. EDIT coinabul? coinad.com

For that matter just get on coinworker.com and do a few tasks.
