[XPM] [ANN] Primecoin High Performance | HP14 released!

[matt4054]

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...

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

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?

Congrats!


Next project; improve HP3???

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.

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.

Should the sievesize be a prime number?

After all, I think that the performance is lower with -march=native, it could be related to my AMD processor fake 8 cores. I could still give a try to march=native to try.

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.

That's the route I took - VirtualBox/ubuntu -  been running 4 of my cores at about 3500pps with Mikaelh2 build.  Found 3 blocks but nothing in the last 24 hours

Well, to be honest his build is probably the best, but I don't have the guts to run a binary made by a new guy at bitcointalk.

[jubalix]

does any one have a script to start

primcoind --deamon

if it falls over?

if(check/5 mins if on watch process!)
{primcoind --deamon;}

[hiddenvalleyranch]

I'm getting about the same rate but my CPU is way down like less than 20% most of the time. Anyway to allow it to use full CPU. Win 8 by the way.

[achillez]

I heard about the a "hp3" build? Is this in the git repo for mikaelh2?
