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.

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.

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

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?

Finally managed to build it on Ubuntu 13.04 amd64, it gives me around 4500 pps on my FX 8350 Cheesy

Congrats!

Next project; improve HP3??? Wink

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

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

Shocked

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?

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

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

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?

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

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.

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.

Hp1 report higher pps, but he find less block.
Still, bad luck
