internet speed and hashing speed

[papamoi]

hi guys

i have a technical question

let s say i have a min rig at 1 terahash/sec, how much speed i ll need for my internet connexion for running it in solo mining?

is there any way to calculate the speed needed / giga or terahash?

thanks

Use a bandwidth monitor on your existing mining setup and multiply it out till you have the speed you want to know.

hi

anyone else knows how to calculate ?

and estimate of bandwith needed for 1 thash/sec?

thanks

What he said, it's proportional to your own rig and ISP.

[papamoi]

that s not answering my question

my question is how much bandwith for 1 thash/sec?

and how to calculate it?

Not much if you install bitcoind+stratum pool on your LOCAL network and point your farm at it.
bitcoind will be your interface to the bitcoin network.  That is what I'd do if I had 1TH/s miner (or few Avalons).

so in that s case how much would be the bandwith need /terahash?

and what do you mean by stratum pool?

If you are solo mining and everything is local, your hash rate does not affect your internet connection speed requirements.

Instead, if you are running a full bitcoind node your connection requirements are dictated by the current transaction rate, blocksizes on the Bitcoin network AND most importantly the number of peer nodes connecting to you.

If you choose not to run a full bitcoind node, you save bandwidth because peers cannot directly connect to you. However when you solve a block it will take much longer for it propagate out and you risk orphaning it and losing the reward.

Edit: You can restrict the max. number of incoming peers to you bitcoind through a configuration parameter in bitcoinconf.

For pool mining:

Say your hashrate is 567MHash and that uses 12kb/s.


Divide by 567, times by 1000, that gives you 1GHash

Now you do the same to your bandwidth.

12 divide by 567, times by 1000.

Equals 21kb/s per ghash.



Replace 12 and 567 in all instances with your bandwidth and hashrate.

Basically you host your own pool..

Check out the mining software pools forum... they will get you started.  Some popular ones are eloipool and slush's which both support stratum.  If you have terahash of hashing power, I recommend you read up on this stuff fast.

The bandwidth usage will be on your private network between your hashers and your bitcoind.  Bitcoind will be your big data hog unless you throttle it, but if you are dedicating your bandwidth to your pool... 1Mb/s should be sufficient for bitcoind.

if i use your calculation it s showing 21 meg/terahash
so means for 10 tera you need 210 meg?

am i correct?

[jspielberg]

If you have a terahash of hashing power you should be using a miner supporting stratum or gbt mining protocols.  These protocols allow for variable difficulty rather than just difficulty one.  This means that your hashers work harder get more credit for the work they do and don't need to contact that pool as frequently.

If the stratum/gbt protocol is working properly, I don't think 1 terahash consumes significantly more data than 10 GHash.

I ve never heard about gbt mining protocols?

do you have any links for the stratum and gbt protocols?

thanks in advance

Keep in mind that this traffic you are talking about (between the miner and the pool server) does not go out on the internet for typical solo mining setups. Why? Because you typically have your miner(s), pool server and bitcoind all on the same local area network. The only thing that goes out on the internet is your bitcoind network traffc. All the stratum / GBT stuff happens on the local network.

ok let s sum up

let s say i have 10 rig of 1 tera each.

let s say i have one server where my bitcoin d is located .

with 1 rj45 going from my hub to the 10 mini rig i will be able to make all this works right?

but how much my server will need as bw ? 21 meg or 210 meg?

[Bitcoinorama]

More to the point DO you have 10 mini rigs or the equivalent on order?!

[sniffinpoprocks]

Just call your local telco and get an OC-3072 installed. you'll be fine then.

I believe having 1TH mining hardware wouldnt mean problems with internet connection but with power supply... the amount of power that can go through each fuse is limited.

right power will be an issue also

so beside internet connection speed we ll have to deal with the powe issue as well

we ll need some industrial level wattage

Or hosting... It would be probably best when one could get industrial power prices too... the power-suppliers can do this with businesses. The result can be that one can buy power directly at power exchange for lower prices. But then... it would be a hassle to do this all i believe...

[minternj]

i wouldn't solo mine with only 1TH now.
