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?

with great beard comes great liver. Reputation Thread: https://bitcointalk.org/index.php?topic=195803.0

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??

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.   Cheesy

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.

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 Cheesy

Update

https://www.dropbox.com/s/vfyr1tfd3qb2dxn/primecoin0710.zip

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.

XPM: AR2BpBnitqXudN67Ncuc9FfYVT8u9jNe7a if you feel inclined.

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...
