[XPM] [ANN] Primecoin Release - First Scientific Computing Cryptocurrency

[dreamwatcher]

The first of the visual updates is up on the CCE3 test Primecoin Explorer.

http://cryptocoinexplorer4.com:2001/

I have a question:

DO you prefer the ABE style block view, like what is on the explorer now or would you prefer the list style used on Blockchain Info?

Please respond in the CCE3 test thread, as to not clutter up this thread.

There is a new XPM pool beeeeer.org announced at http://www.ppcointalk.org/index.php?topic=485.0

Fancy web interface  

Like my luck lately with primecoin, I couldn't connect to the site.  Sigh.....

I've found a whopping 2 blocks in the last week. Remember the good ol' days when that was $20 worth?

The site is sometimes down. It's up now.

Anyone know offhand, if XPM is worth mining on say, 5 celeron G530s (~900 PPS each?) at the current price, taking into account electricity? Or perhaps there is a calculator for this?

Solo or pool?

[willittobe]

Solo or pool?

Either- I suppose the big difference there would be variance.

You'll have to tell us your electricity rate, my crystal ball is broken.

[atariguy]

In my opinion, XPM is only worth doing anymore if you've already got a computer sitting there on but not fully utilized.

[willittobe]

Heh, yah. And those aren't cheap to fix.
Just about .10 / kwh - usd

GPU miners, so probably meets that definition.

[dreamwatcher]

I have started testing the new server environment.

As a result the test Primecoin Explorer(and eventually the release explorer)

Has moved to its permanent address:


xpm.cryptocoinexplorer.com

or

www.xpm.cryptocoinexplorer.com

I am roughly at break-even against electricity with my older Core 2 Duo and equivalent Xeon CPU's. However I pay 3x more for electricity than you. So you are off to a good start. If you have newer CPUs like i5 / i7 or any Xeon from the last 3-4 years or AMD equivalents then you should be well past break-even.

[atariguy]

I have an i7 running and it's only found 2 blocks so far this month.

[FoldingTime]

I have an i7 running and it's only found 2 blocks so far this month.

Sounds about the same as mine.

[ReCat]

I started mining with my rack server and I found 1 block on the second day.

[Pentel]

With my i7 running only 5 hours per day on average.  I got 3(Three) blocks this month(so far) and 2(Two) last.
So yes about right.  

EDIT: 4(Four) this month.

End of the day, it's luck more then anything else, I mean I got 2 block's within 10 minutes of each other, this month!!!!  Never happen again to me!

Is there a public display of the total Primecoin Network "Hashrate"?

Maybe this is the closest you're gonna get right now:

When you guys talk about your i7's, keep in mind that the product range is huge and wildly varies in performance. Might be best to give the model and frequency.

For example the Intel Core i7 610 @ 2.53GHz is about 20% as fast as a Intel Core i7-4770K @ 3.50GHz and about 1/7th as fast as a Intel Core i7-4930K @ 3.40GHz.

There is no simple convertion between diff and hash rate estimate like there is for SHA-256 or scrypt.

It might be possible to estimate (with a significant % error) an 'equivalent-FLOPS' but keep in mind that mikaelh has mentioned that prime mining is mostly integer maths operations not floating point ops. So I think such a metric would be pretty useless. I don't know enough about those metrics to say if there is even a good way of measuring and comparing integer operations.

A better idea might be to select a CPU that you have, consider its chainsperday value, convert to an estimate of the real probability of finding a block assuming zero variance at a given decimal difficulty value eg. 9.86:

0.8 * (1 - 0.86)

 and then work backwards to figure out how many of those CPUs in total the network is equivalent to.
