My improvements to poclbm

[Luke-Jr]

https://gitorious.org/~Luke-Jr/luke-jrs-poclbm

Changes:

• Real-time statistics show more than just hashrate-- also estimated hashrate (based on accepted shares), rejected share count and percentage, getwork count and efficiency (accepted/getwork)
• Optimizations around share submission
• If share submit fails, save it and retry a second later

Have you ever found a pool that has accepted a share that your modified client has attempted to resend?

Normally a rejected share won't be fixed by resending it.

Rejected shares aren't resent. That's only for network issues.

Okay understood. Sounds cool.

I were assuming a set of patches, but apparently not. No reason to be an jackass for a valid point.

no, i can't find the binaries either, just the source files.

It's Python. There are no binaries.

poclbm looks like python too, but has binaries. and how do i use the source?

Code:

c:\Python27>python2.7.exe bitcoin-luke-jrs-poclbm\BitcoinMiner.cl
  File "bitcoin-luke-jrs-poclbm\BitcoinMiner.cl", line 2
    typedef uint2 u;
                ^
SyntaxError: invalid syntax

c:\Python27>python2.7.exe bitcoin-luke-jrs-poclbm\BitcoinMiner.cl  -d 0 -o mining.eligius.st --port=8337 --user=asdfghjkl --pass=x
  File "bitcoin-luke-jrs-poclbm\BitcoinMiner.cl", line 2
    typedef uint2 u;

The Windows release of poclbm uses py2exe to create an EXE for us lazy Windows users

You use it by doing "python2.7.exe bitcoin-luke-jrs-poclbm\poclbm.py"


Luke-Jr: Great work! I merged this with my branch and it seems to be working wonderfully so far. I haven't measured connection performance, but it's very nice to have it tally up the rejected statistics and such. Thank you for this great improvement to poclbm

That's what I do too but it raises the error.

Code:

Traceback (most recent call last):
  File "poclbm.py", line 3, in <module>
    import pyopencl as cl
ImportError: No module named pyopencl

How to install pyopencl? I never used python.

[fpgaminer]

That's what I do too but it raises the error.

Yikes, yeah. Well, to be honest, pyopencl looked like a bit of a pain to compile when I took a look at it last, and I couldn't find anything pre-compiled. Hopefully someone else can chime in here.

Other than that, you may want to take a look at my branch, for which I did put together a ready to run Windows exe:
http://forum.bitcoin.org/index.php?topic=19169.msg254264#msg254264

For that one I copied over the pyopencl binaries from the original poclbm packaging, so I didn't have to compile pyopencl. 

My branch includes luke jr's modifications, but it also uses the phatk kernel (which may give you a speed boost).

[Ali]

I'm using your branch now fpgaminer. The phatk-kernel gives me a boost of about 12 MH/s.

What does the Efficiency value mean?

[SoreGums]

What does the Efficiency value mean?

yeah, i'm wondering the same thing

is 359%,380%: good, great, ok, awesome

[Luke-Jr]

What does the Efficiency value mean?

Same thing it's always meant with regard to mining. Percentage of getworks that result in a share. With roll-ntime, fast miners can easily milk lots of shares out of each getwork.

ok so 100% is 1 share for 1 getwork?

edit: ok i get it now. eff = accepted shares/getwork*100 - simple really

[Detritus]

Great work luke-jr

I made some minor tweaks to the status display line to show three digits of precision on the display of reject and efficiency percentages.

A lot of times rejects is between %0 - %1 and being able to see the fraction of a percent is handy (well to me anyway..    )

 here's and examples of the modified display...

Code:

[401.772 MH/s (~444 MH/s)] [Rej: 13/1635 (0.795%)] [GW: 2704 (Eff: 59.985%)]

and here's the diff of BitcoinMiner.pl that implements it...

Code:

bigfoot@brontosaurus:~/bitcoin-luke-jrs-poclbm$ diff ../luke-jr-poclbm/bitcoin-luke-jrs-poclbm/BitcoinMiner.py BitcoinMiner.py
149,150c149,150
<                       eff = self.shareCount[1] * 100 / self.getworkCount
<               self.say('[%.03f MH/s (~%d MH/s)] [Rej: %d/%d (%d%%)] [GW: %d (Eff: %d%%)]', (rate, round(estRate), self.shareCount[0], totShares, self.shareCount[0] * 100 / totSharesE, self.getworkCount, eff))

any chance that we <windows lamers> get compiled binaries

fgpaminer compiled them in his version (which also uses the phatk-kernel).
