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

[arnuschky]

Getting a dependency error on my fresh cent 6.4 install, any thoughts? I dont see a source for this lib for this version of Cent.

[rahlquist@corgi 64]$ ./primecoin-qt
./primecoin-qt: error while loading shared libraries: libminiupnpc.so.9: cannot open shared object file: No such file or directory

You don't need a source package. You are missing the library itself. The package should be called miniupnpc on CentOS. Try yum install miniupnpc

Is it already too difficult to get some results?

I'm mining with an i7 and get ~800-1000 pps. But didn't find anything in the last 20h 

I think it might be already too difficult. I'm running on OS X 10.8.4, and I set up an Ubuntu OS in VMWare Fusion. It's running around 600-700 ops, has gone through almost 80,000 blocks in 24 hours, and there's nothing produced so far. I'll let it keep running for a few days. I understand that luck is a major factor, so maybe lady luck will visit me.

Why not run native? you could probably get better PPS than that. and the code compiles fine native OSX.

The simplest answer to this question is that I was able to find a great guide (like "Mining Primecoin for Total Dumbsh*ts") for Linux, but not one for OS X. I understand the very broad concept of compiling code, but I am not familiar with actually doing it.

Not source code, a source for the RPM. And no yum isnt showing one either.

You can compile the binary without upnp:
Set USE_UPNP:=- by editing the file "makefile.unix" in the src-directory:

Code:

# :=0 --> UPnP support turned off by default at runtime
# :=1 --> UPnP support turned on by default at runtime
# :=- --> No UPnP support - miniupnp not required
USE_UPNP:=-

It's on RPMforge. See this link how to enable this in yum:
http://wiki.centos.org/AdditionalResources/Repositories/RPMForge

Then, you can install using the command you've tried above.

I assume that you are using the binaries. If you did compile it yourself, see masterOfDisaster's comments on how to disable UPNP completely.

Thanks but thats not a current enough version it installs libminipnpc.so.5

I may have to try to compile this myself, but doubt I will go to that effort I was mainly going to use it to test this new system for a day or two.

Looks like there's an issue with the Linux Qt binaries in the HP7 release. They use dynamic linking for all libraries instead of static linking where possible. I will update the Linux binaries soon.

Updated Qt binaries are now up.

Oh yeah, there are still the glibc and libstdc++ dependencies. Those are quite hard to get rid of. For now your best option is probably to compile it yourself. You can try taking a few pointers from my guide here:
https://bitcointalk.org/index.php?topic=259022.0

That only shows how to compile the daemon though. You'll need to install the Qt development packages in addition to compile the Qt client.

Does anybody have a recommendation on how to keep my keypools in sync?  I just noticed that when a block is mined it makes a new address that doesn't show up in getaddressesbyaccount "".
Although, I can still do a dumpprivkey on it.

[arnuschky]

Where can we report feature requests now as the github account is disabled?

mikaelh, would it be possible to add the 5-chains value to the mininginfo rpc call and/or add a separate rpc call for it? Just like for getprimespersec. That would be really handy for measuring performance!

[eule]

I'd like setsievesize and setsievepercentage

That's already done. It's called (get)chainspermin.

A setsievesize command isn't really possible with the current code. OTOH, setsievepercentage is possible.

People starting to mine should know that by now block finds are rare even on i7 3770k @ 4.4 !
I used to find a block a day and I have found none during the last 72h...

same here

[Stinky_Pete]

Still getting new blocks mined on my i7-970 Gulftown at 3.2GHz (2 today, 2 yesterday). Maturing seem to take at least 48 hours, so I'm guessing a lot of machines have dropped out of the network.

Cool, I missed that! Thanks.

What settings are you using and how many primes per second are you getting? I'm mining  on my 3930k and get anything from 4k to 5700 primes per sec and have only gotten one block in three days of mining.

The difficulty is still going up so there are definitely more people joining than leaving.

It really is hard to tell if/when you'll get a block.
I don't mean that as in "I don't know how to calculate it", I mean it in the sense that "I'm not sure if it can be calculated".

Prime numbers and prime chains are quite fickle and inconsistent things.  With hash-based cryptocurrency, there's a certain uniformity and predictability with difficulty.  With primes and prime chains, there's some predictability, but not enough to get you a simple formula.  See the "Difficulty Adjustability of Proof-Of-Work" of the primecoin paper.

With hash based coins, the question is simply "if I throw dice with X sides, what's the odds I'll get a number lower than [difficulty]".
With primecoin, the question is "what's the odds that I'll find a chain of primes [difficulty] numbers long, with the next number not being prime and having a remainder greater than [difficulty]".


So yeah.  I have no idea (and neither does anybody else).


P.S.: Just because you're finding X primes/sec doesn't mean you'll find them with the correct properties.
