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

[Tuck Fheman]

Those are ypool stats I believe and have nothing to do with hp9.

He is correct. lulz, I'm in the wrong thread. I visit that thread, then this one, then the gpu and got mixed up. Sorry.

Did the devellopement of the HP release will continue or Mikaelh is occupied with the official client?

I saw in the previous page there is a 6% improvement possible. Maybe with some other trick, we could go to +10% with HP10.

I finally got brave today and checked all of my computers.  6 days, 5 computers (2@~.8 and 3@~.45 chains per day), 4 blocks.

Needless to say, I are happy!

Do you mean you're not checking at all? At least, you make sure that everyone is still mining, right? It would be too bad to have idle miners for days

I have one main system I use with 4 others in the house currently operating (need a PSU for one, some troubleshooting on another and an old AMD laptop I doubt would get .05 chains per day).  Since I was clueless about wallets, I have 1 on each system.  I guess I should check that they are running more often, it's just that if I saw 2 blocks one day and no blocks for 3 days(which did happen), I might get discouraged and switch and miss the next 2 blocks.  Mining is still in the 'hobby' stage for me, so the 'loss' would not be a big deal.  Being retired, I don't have a huge need for the mining income, but it's nice to see

Why would you care about having a different wallet on each system?

My understand from reading about the VPS' is that one wallet with 10,000+ 'addresses' can be used on multiple systems and thus you only need to check 1 to see all.  Since I have 5 wallets on 5 systems, I have to manually check each system to see if it mined anything or not.  Call me lazy, but I prefer not ro run from computer to computer throughout the house checking balances daily.

Just set up a script that sends the funds as soon as they mature to a central wallet. If you're on linux, it's just a oneliner to execute periodically:

Code:

b=$(primecoind getbalance); if [ $(echo "$b > 0" | bc) -eq 1 ]; then bminusfee=$(echo "$b - 0.01" | bc) && primecoind sendtoaddress <your_central_wallet_address> $bminusfee; fi

(not tested)

Yeah, I've been manually checking each and then exporting immature blocks to one wallet to track them (and also in case I blow through my credits on Azure before they mature). At least I'm half efficient that way.

But how does that work (the one wallet idea) since each block that's mined gets a new address?

I pushed some big optimizations for -hp10 to github so that more people can test them.

Any chance of getting a compiled Windows binary? I'd like to test on a 32 core Opteron rig and a 3930k.

Thanks man!

[ivanlabrie]

Nice! I'll keep my eyes peeled for this...Might install ubuntu and compile it myself.

[bidji29]

"Roundsievepercentage" doesn't show on the mininginfo anymore.
It's replaced by "sieveextensions" (default value : 6 )

Any info on that?

"Roundsievepercentage" is gone. The round primorial is now adjusted automatically.

"Sieveextensions" is a new parameter which controls the new big optimization. jh00 discovered that the sieve can be "extended" efficiently to numbers that are two times bigger. That parameter determines how many times the sieve is extended (each further extension will produce numbers two times bigger than the previous extension). Bigger numbers will have a lower probability of hitting primes and prime chains but each extension is pretty cheap. Six extensions seemed like the optimal value for mainnet.

holy crap hp10 is 2x as fast as hp9

[shazbits]

Do you compile with make -f makefile.unix USE_UPNP=- or is there some optimization flags to set? A bunch of other miners and posts mention msse2 -O3 and some others I think.

wow, are the sources available ? I'm not used to git :/

Compiling the client with -O3, -msse2 or -march=native is not going to make a big difference. The sieve currently doesn't benefit from SSE2 or any other special instruction set. The default -O2 optimization level is more than enough.

GMP does benefit from compiler flags. The "configure" script that comes with it tries to detect the best settings if you compile it yourself.

You can download a ZIP from github if you want.

[Tamis]

ok I got the sources, thx !

I'm compiling it the same way that you showed on your Linux Compilation Guide. Is this the right way to do it ?

It should still work just fine. You just need to change in which directory you compile.

[arnuschky]

Does anyone have optimized compilation flags for the AMD bulldozer architecture? This processor is severely under-performing, worse than CPUs years older!

PS: I can confirm hp10 is faster
