How close does that come to paying for itself these days?

Incidentally the cc2.8xlarge is not the most cost effective for xpm as the L1 cache appears to be a bottleneck. To prove it, try running just 16 threads instead of all 32 and you'll see little difference!! Or at least that was true for hp9. You can get more bang for buck with 8 cores.
I noticed this as well. Even though the cc2s put out amazing numbers the ROI just doesn't seem to be there (get 2-3x as many larges). Would be nice if there was something in between

How close does that come to paying for itself these days?
In my experience they do not. Variance/luck killed it for me, some days a loss/some good, but overall the profit was getting too low for my tastes. That was with 50 instances which is a small number so YMMV, esp with the "luck" factor.

Multiple c1.xlarge

That's mostly luck. You may get zero blocks, you may get several. Northern Virginia c1.xlarge is ~0.07 an hour. I have found about 4 blocks in 2 weeks (3 of them have been today though). Quick rough estimate, I earned 0.25 BTC and paid $23.52. Very slim margins, though still profitable, *IF* you're lucky. I'd advise trying it out and seeing, killing the instance when it gets to 10 Difficulty.

Cool, thanks for the clarification.  Just FYI, I did a major test (500-1000 machines from 4 to 16 cores for several hours) of both HP9 and HP10 on mainnet and for the most part found that the default settings you had selected were the optimal.  When I did the HP9 test it was just about profitable enough to run for a full day and cover costs (though I had my wallet hacked/stolen along with my entire XPM collection!)  HP10 was not even close to profitable, so I won't be running any more tests unless there is a likelihood of 2x performance Smiley

I think it's time to turn your attention to the GPU now Mikael Smiley

Running hp10 since monday morning, found 3 blocks on monday with 20 cores, none today - guess it still comes down to luck Cheesy

Oh and 2 blocks over the weekend with hp9

Which instance type did you use? I found the c1.xlarge is the most cost effective. By running HP10 the blocks generated can cover 90% of the bill, given I bought the discounted AWS Credit code to fund the running cost, I am still at profit with sizable margin.

If it only covers 90% of the bill, how are you "still at profit with sizable margin"? And the falling exchange rate certainly isn't helping...

Because I use the AWS Credit purchased from ebay - the discount of 50% contributed to the profit margin.

Indeed. Between the PowerOf60 promo and 3 ebay credits (Max I think or maybe by promo) you can get $400 worth of compute time for ~$150. But past that it wont pay for itself Wink

Edit: Math fix. Could of sworn the PowerOf60 was 200, must be thinking of Azure.

There are a couple of types. Some people are reselling the Intel Promo codes (i.e. Power of 60) and you can only use one of those. There are others.

There is another type of code, that you can apply three codes to each account.
