ok this is officially crazy

on a E2 8cc

build  1 = original hp2 compiled = found 7 blocks 2 orphans [17 - 11K pps]/24 hrs
build  2 = original hp1 compiled = found 5 blocks 2 orphans [20k - 16K pps]/24 hrs
build  3 =  AWS image of hp1, compiled = found 0 [20 - 16K pps]/12 hrs
build  4 = original hp2 compiled = found 0 [17 - 11K pps]/12 hrs
build  5 = original hp2 compiled = found 0  [17 - 11K pps]/12 hrs
build  6 =  AWS image of hp1, compiled = found 0 [20 - 16K pps]/3 hrs [now deleted instance]
build  7 =  AWS image of hp1, compiled = found 0 [20 - 16K pps]/3 hrs [now deleted instance]
build  8 =  AWS image of hp1, compiled = found 0 [20 - 16K pps]/3 hrs [now deleted instance]


there is no way that the blocks would all would be found in just the first 2....

is statistically impossible

there is something going on here

Are all these started in parallel? Can it be explained by the change of difficulty working in different timeframes?

What's going on is that you do not understand statistics at all.

IIts statistically unlikley that none of the other instances find zero, while the first two find blocks, it's geting to the point where p<0.05 so statistically significant.

What peer IPs are you connected to? Yourself? ARe you talking to your own servers indirectly working together to solve with them? Someone explain is this is kind of possible given the Peer to Peer technology implemented in mining.

These numbers for 8 core instances are great actually

Actually Sunny King was just turning his server room on and off. There's your reason.     Cool

I'm getting pretty abysmal performance with this build on osx (using the osx makefile). 1player's build seems to be working better on osx while all other machines are better using mikhael's hp3. Any suggestions / optimizations to the osx makefile would be much appreciated.

I'm tempted to VM an ubuntu build and see how that goes but I'd rather run it natively in osx with this high performance build.

Where did you get your libgmp? That's what's doing most of the heavy lifting. I would probably look for optimization opportunities in how libgmp is compiled.

As far as I am concerned, I got it fresh from the current MacPorts

I found that installing libmpfr-dev which it required for Freicoin, also satisfies the gmp requirement.

Is there a difference in speed between the mpfr and gmp libraries?

libmpfr-dev pulls libgmp as a dependency. The actual mpfr does floating point calculations. Comparing mpfr and gmp is like comparing apples and bananas.

Well I tried "sudo port uninstall gmp" and then "sudo port install mpfr". Then I recompiled. It compiled without errors but the performance was even worse than not having mpfr installed (with macports).

I'm at a loss now... Sad

Just found another block. 4 blocks in 24 hours @ 2500 PPS.

I'm so jelly. Hold onto those precious coins.



 I've been well over 3000 for the last 48 hours. Nothing. I made sure do re-download the blockchain before switching builds. No excuses. Just bad luck?

Thank you.

I did not know that it used gmp as a dependency.

I see so many libraries and packages that appear to do the same things. Some better at certain applications while worse at others.

I guess the next major step would be to rewrite the mining routine in OpenCL. Though I would not doubt somebody has already did it and is not sharing.  Cheesy

Can't say I would blame them at this point.

In my case it's weird, if I compile with march=native the pps rate is lower.

Yeah, I was thinking that earlier. It seems a likely explanation to the skyrocketing difficulty (that surprises even Sunny).

I'm curious - how / why were OCL miners even publicly released anyway? What caused the person / group to release it/them and not horde anymore?

Remember that having too much control of a decentralized network by a single person reduces the trust that the public has on the network, that is bad for the guy hoarding the miner. Best is to mine a nice time with the OpenCL miner then when you have your stash just release the miner to the public to make your stash worth more.

I was poking through prime.h and prime.cpp and they're not really all that long. Someone who knows c++, OpenCL and / or CUDA should be able to make the conversion. I would be willing to bet it has already happened and they're raking it in at the moment.

Remember, PPS isn't an accurate measurement.
