[XPM] Primecoin Built-in Miner Sieve Performance Issue

[TheSwede75]

Let me know as soon as you guys find a block!  I'd like to make sure it is actually working on the live chain...

will do

are the compiled binaries up ?

Not yet, sorry.  Working on getting them compiled.

no need for apologies your doing good work

are you compiling a windows build ?

I never got the windows compilation to work when this first launched on Sunday, so I've been doing all my development in Xubuntu 12.04.  There are some guides in the main thread (https://bitcointalk.org/index.php?topic=251850.0) if you need help compiling.  Not sure the exact pages they were on, but somewhere in the 30-60 range

Windows build would be amazing!

Sollid 50% increase in pps with your patch, thanks! (Ubuntu, single core Xeon based VM).
I'll let you know if I find a block, but I've been mining since release and only pulled an orphan, so far, so... 

Am I the only one experience a pps decrease? Dropped from ~4500 to ~3000...

[Kouye]

I'm observing wide variations in pps with Chemisist patch, anyone else ?
Ranging from 170 to over 300, while official release was more stable @around 150.

[Chemisist]

@Chemisist

First block with https://github.com/Chemisist/primecoin

Hell yeah, thanks for letting me know!  

Am I the only one experience a pps decrease? Dropped from ~4500 to ~3000...

what kind of system are you running this on?  I've only tested this with my intel processor lineup

[Kouye]

You compiled it with the exact same switches and options ?

The Chemist version has -O3 flags changes for the record.

Is the O3 flag using more memory under compile or under usage?

exactly the same

Code:

make CXXFLAGS="-O3 -march=native" -j16 -f makefile.unix

Then PPS drops, I will switch back to primecoin/primecoin.git untill I figure out the problem.

How many cores is that running btw?

How do you grab the https://github.com/Chemisist/primecoin via linux command?

[Chemisist]

Silly question, but where do i find the latest patched/optimized branch that I can build on ubuntu ?

https://github.com/primecoin/primecoin

if you don't  have git installed:
sudo apt-get install git

then run
git clone https://github.com/primecoin/primecoin

(or git clone https://github.com/Chemisist/primecoin for my optimized version, until the pull request is committed on the main branch)

then follow the instructions in doc/build-msw.md

this.

Saw a decrease on my virtual servers too, but only when multiple instances run (from 500 down to 300), when only one instance runs pps go up from 1000 to 1300. On old CentrinoDuo laptop pps remained the same.

16 cores, 32 threads.

Code:

git clone https://github.com/Chemisist/primecoin.git

You need to be root.

exactly the same

Code:

make CXXFLAGS="-O3 -march=native" -j16 -f makefile.unix

Then PPS drops, I will switch back to primecoin/primecoin.git untill I figure out the problem.

Keep in mind I'm getting wide variations in pps, too, but overall it is a solid 50% increase at least.
Maybe let it run a couple more minutes while watching ?

I seem to remember build-msw.md being aimed at building on Windows.

Hmm.  I suppose that this is indicating that my "improvement" pretty much sucks for that many cores/threads, sorry!

yeah, you're totally right... see build-unix.md.  That was pretty dumb, eh?

[jlspartz]

Waiting for windows compilation. Not by my backtrack linux system. Gotta work in 3d win apps, which reminds me I should be working :p but I can't turn down news like pps increase

-O2 generic build: (generally -O3 gives some errors at end but seems to run fine, I'll go the safe route first).
