[XPM] Primecoin Built-in Miner Sieve Performance Issue

[LazyOtto]

I'm using OS X.

With this new code and also the changes I made in makefile.osx:
#CFLAGS = -mmacosx-version-min=10.5 -arch i386 -O3
CFLAGS = -mmacosx-version-min=10.7 -O3 /
         -arch x86_64 -funroll-loops -mfpmath=sse -fomit-frame-pointer

I'm seeing between two and three times higher primemeter numbers than before.

Still have the problem that I must run a discrete instance per core rather than just letting primecoind spin off threads.

[Entz]

From the reports I have gathered, it impacted some server systems with high thread count, yes it may impact atoms as it's threads are relatively slow.

Awesome! I gave up on trying to mine on my opteron (pps between 0 and 1) so hopefully this helps!

Making a huge difference, while I realize primes per sec is a not the best metric. I have gone from a max of 1 to 204 on my Opteron 6174 (using 8 of the 12 cores)

Edit: Make that 500

[LazyOtto]

With your report, Entz, I probably need to run this test again. Perhaps I did not give it enough time to get off of zero pps before I lost patience.

How do you compile that github file? Please someone explain this to me. I am running windows.

And then you'll need a C++ compiler like Visual Studio.

And all libraries needed ...

This is on Ubuntu, so hopefully it works the same in OSX. Takes a few mins to climb as always. I am going to guess that haveged is mandatory as well

{
    "blocks" : 8728,
    "currentblocksize" : 1000,
    "currentblocktx" : 0,
    "errors" : "",
    "generate" : true,
    "genproclimit" : -1,
    "primespersec" : 2318,
    "pooledtx" : 0,
    "testnet" : false
}

Patch does something

Will Sunny King do this for us soon?

Windows update is very much needed for this to reach a larger user base.

Edit: I am indeed a noob

[eule]

Those are the source files, i.e. not compiled.

I'm downloading MinGW now, let me see if I can get it working

[ivanlabrie]

nice, now, how to do this on ubuntu console...gotta figure it out on my own :p

When I compile on windows with mingw32 and then run primecoind it gives error: can't connect to server. Does anyone know the cause?.

I get that error on linux when I forget to sudo

I think it has to do with this error at compiling stage, after that part everything ends with something has different size:

Code:

obj/rpcdump.o: duplicate section `.data$_ZGVN11json_spirit10Value_implINS_13Conf
ig_vectorISsEEE4nullE[guard variable for json_spirit::Value_impl<json_spirit::Co
nfig_vector<std::basic_string<char, std::char_traits<char>, std::allocator<char>
 > > >::null]' has different size

Are you compiled in Linux then what? Do you have to run primecoind.exe or do you run primecoin.exe? How do we use primecoind.exe if that is necessary because when I run it I seem to get nothing.

You need to run it as a daemon

primecoind --daemon

without it thinks your trying to connect to the server to send a command (for example getmininginfo).

In my case primecoind runs but doing nothing, and then if I open another cmd window and type primecoind.exe getinfo it tells me error: can't connect to server

How to use it?

cd ~/ ; git clone https://github.com/primecoin/primecoin ; cd ~/primecoin/src ; make -j8 -f makefile.unix ; mv primecoind ~/ ; rm -Rf ~/primecoin/

What is the -j8 parameter on the make command?
