[XPM] Primecoin Built-in Miner Sieve Performance Issue

[spoid]

just booted ubuntu as well to try these out. work fine - improvements on my i7 and i3 are just as described in this thread.

I'm curious - does the getbalance command show the mined "immature" blocks?

I think i'm doing it wrong.

Editing the file with notepad++ is enough or not?

Because i don't see my pps change

No. the sourcecode that you edited must be compiled first. Easy on Linux, bit harder on Windows, which is why it will take a bit until an exe will be made.

@ spoid: No, use listtransactions for that.

Any evidence that anyone is finding blocks with optimization? yea you may be getting more PPS but are you finding blocks??

[Vorksholk]

Did anyone get issues like

key.h:112: error: ISO C++ forbids declaration of âEC_KEYâ with no type

when compiling? I'm using make, and I installed gcc, gcc-c++, Development Tools (build essential), libboost-all-dev, and openssl-devel. I'm on centos-6. Odd.

primespersec number is larger, but have no feeling with larger chance to find a block.

Need to run much longer to tell.

I wasn't finding blocks before.

So this new version is at least as good.

Here is my qt compiled on an i5 under windows 7 with the latest updates from Sunny. As the previous guy who posted a qt said, do your due diligence before using this... encrypt wallet, run thru virus scan, etc.

If you found this helpful and feel so inclined.

Impressive. CPU and pps? edit: Oh i guess 4500 pps. 

Also thx anonppcoin, works great!

What is the night without some teasing..

10 x quad xeon 4500-5100 pps
1 x xeon 1200-1500

Ok i'll post a few builds I have here so people can test for themselves.... I'm on the 2nd  build and i gone from 10-20 PPS to 210 and still rising!!
All these are builds for linux. Those of you who been round a while should know me and know i'm not a scammer, but encrypt and backup ur wallets. Note these are just daemon builds not Qt
http://donate.ppcointalk.org/primecoind.zip - code with first fix and compiled under make -f makefile.unix
http://donate.ppcointalk.org/primecoind.tar.gz - latest code fix and compiled under make -f makefile.unix

building one now under  make -O3 -march=native -f makefile.unix as this supposed to be better??

All tips appreciated: APkVyn9uJ8LvkGgkQeyamUig4h2bFew8AD

I'd do mtune=generic instead, which tunes to the most common cpus, since march=native will produce code that only runs on your cpu.

Oh how I wish I had some Xeons.

Could you please build for static so we don't get "./primecoind: error while loading shared libraries: libboost_system.so.1.48.0: cannost open shared object file: No such file or directory."? Thanks

I can confirm that the new windows setup produces blocks from 40pps before reading this forum to 1400 and my first prime block

thanks guys ill tip a few when i re-read through and see who they need to go to once matured

This is a fresh pull using -O3 and mtune=corei7-avx compiling options. In other words, it is optimized for AVX instruction processors (Core i3, i5, and i7) but will run on any hardware.

This is on my i5-2400:

I was getting about 120 PPS earlier today, so a huge improvement.

Can anyone dropbox a compiled QT client? There are a good 10 or 20 people getting left out.

Just pushed another commit on github.

https://github.com/primecoin/primecoin/commit/eda38d62ad571be02095ce44469c0cc26a2b3675

sieve round limit further reduced to 1 second.
added mike's suggestion.

Give it a try and let me know how it goes.

This code produces a 3-4x performance improvement for me, but I haven't found a block yet running with the new code and found 5 with the executables on primecoin.org.

Hopefully it's just a matter of time before the new blocks start coming in...

I need a virus check on these files please.
