Best CPUMiner for quarkcoin.
i3i5i7_Improved2 best hash

If you are going to use the CPU's do not use cgminer! Use Pooler's CPU miner! Works much better/faster.

Well, yes if you calculate power costs LTC is not worth it at the current exchange rates. But I thought you didn't have to pay for power

If you include power costs, your best option would indeed be to mine CPU only coins. Or, like I said before, mine new scrypt coins right after launch for +/- 2 days, get a lot of coins, and hope the value will rise. This is a bit more gambling, since most new coins barely have any value when they start.

Anyway, good luck with setting things up!

Hey folks this is how to make it work on Ubuntu 13.10



Start of Tutorial.

cd ~

sudo apt-get update -y
 
sudo apt-get install -y git make g++ build-essential libminiupnpc-dev htop

sudo strip bitcoind
sudo cp -f bitcoind /usr/local/bin/
 
mkdir ~/.memorycoin
 
nano ~/.memorycoin/memorycoin.conf
 
Put those inside (make sure to change user to user name and user to user password of your choice)

I don't think starting your own pool would be a good way to do this.

Have you made any calculations? It depends a little on which i7 you have, but since I don't expect your employer to buy computers with high end CPU's (actually the fact you have i7's is already quite rare, you see i5's or even i3's way more often), lets say you can get ~35kh/s per CPU. That would set your total hashrate at ~3255kh/s, which is quite a nice hashrate, comparable to around 3x 7990 GPU. But, most pools are in the order of several hundred mh/s, and you only get 3.3mh/s.

Since the chance of finding a block is highly correlated with the total hashrate of a pool, I think it would be much better to join an existing pool.

Having that said, the suggestion of Jothand is actually a great way to do this. Set up your own pc as a stratum proxy, and have all the other pc's point at your proxy. If you want to switch pool/coin, you will only have to change the setting on your own computer, and all others will automatically work for that pool.

Apart from mining CPU coins like quark, you could definitely also look at some scrypt coins. Since you don't have to pay power, you could even mine LTC, which would still give you around 1LTC per day at the current difficulty. It may also be worth keeping an eye on this subforum, and mine some of the newly launched coins. At the start of a coin you can easily get huge amounts in a short time frame, which could become a lot more valuable in the future (but this is a gamble of course).

Hi Manobra,

Since the 93 computers do not have good graphics cards you will need to mine with the CPU. Use cpuminer for that. Also, you should set up one of the computers as a stratum mining proxy. Find a scrypt altcoin pool to join and set up a unique username and password for each miner, this will take a while since you have so many computers. Then point your proxy at the pool and point your miners at your stratum proxy. Even if the version of cpuminer you use supports stratum I think it's still a good idea to run your own stratum proxy. This allows you the flexibility of changing pools quickly. Instead of changing each individual miner, you can just point your proxy to the new pool.

You may also want to check with the pool admin first and make sure they allow that many workers. Some pools may suspect you of running a botnet. I use wemineltc.com and I believe they allow up to 100 but will allow more if you put in a request. 

I think you should stay away from mining any sha256 coins and stick with scrypt but that's just my opinion. I suggest trying a few different coins and stick with what you like.

I think if he'd have a botnet, that would give out impression that he is well versed in this 'scene' and would not ask such simple questions.

It is stealing of electricity and installing unwanted programs, so definitively good reason to get fired

If there are no GPU's you should check out some CPU only coins. Quark or the newly announced Memory coin.
