Regular old BTC client running on ubuntu (2150-2500 khash/sec) managed to produce a block last night Wink

My 300 khash laptop got lucky and produced one the first day I used Bitcoin.

That's good news. Thanks

Don't worry, getting BTC now requires supercomputers, clusters and/or botnets Wink

Counterexamples, with Khash/s noted, welcome

Hey, I just made this improvement that will vastly improve your khash/s!

In main.cpp, ~2751, change:
string strStatus = strprintf(" %.0f khash/s", dHashesPerSec/1000.0);
to:
string strStatus = strprintf(" %.0f khash/s", dHashesPerSec/300.0);

Then on ~2758, change:
printf("hashmeter %3d CPUs %6.0f khash/s\n", vnThreadsRunning[3], dHashesPerSec/1000.0);
to:
printf("hashmeter %3d CPUs %6.0f khash/s\n", vnThreadsRunning[3], dHashesPerSec/300.0);

(DISCLAIMER: THIS IS A JOKE.)

I did the same thing with VC++ 2008: https://bitcointalksearch.org/topic/faster-sha-256-msvc-build-453
As I wrote there, the results were slower than stock.

Haven't yet tried x64 or 2010 because rebuilding the dependencies/setting up is a hassle. Your builds give improvement over stock on my system though.

Curious.

It should be the sha.cpp module that matters. Did you modify the source in any way, or specify any special defines?

Ichi: I got 2 blocks in a row back when I was running 1200khash. I'm up to 2500 now, as per the update, so we'll see if I get some more blocks. =)

Here's a weird question.. has anyone actually generated a block with this faster version?

I have a few machines that used to regularly generate, and since switching to this version -- zip. I know these things are subject to random variation, and it could be a dry spell, and the difficulty is going up, but... could it be a bug?

For 32bit clients, this makes a huge speed increase (if your PC supports it)

I was using a little netbook to test with, it could manage about 185 khash/s but his compile does 238 khash/s so over a 28% increase (what I saw in the 64 bit clients), so another thumbs up for this build. (Exe size is smaller too Wink

)

I think he should really present to this devs to get credit for it and some BC because I'm going to send some to him for raising my khash/s up and beyond the already insane levels that I have. Grin

How do we know this is not a scam? Give us your IP to donate with or something so we can make sure you are reputable. I am scared to install it, it might steal my bitcoins.

If I were scamming, what incentive would I have to ask for donations knowing that those who used it would have their account emptied anyway. Frankly though, my username is far more of a verification of my authenticity than my IP would ever be

I can assure you the code is 100% clean.

Sorry to be so skeptical, but there was a victim on this site when someone claimed to have compiled a CUDA client that used the graphics processor to hash. One guy fell for it and lost some bitcoins.

But yes, if I get a chance I will look at the dlls I suppose before running it.

Or, maybe you can release the project files and we can compile it ourselves?

Point well taken, but the CUDA never materialized, this one actually does what he said it does. So if it is a scam, it sure is taking a lot of effort.

no, that's definitely correct.

there is another possibility however... what processor is in your XP machine? if it doesn't support SSE2, it'll crash.

Tested it a Celeron machine (1.1 GHz)

Good point, I'll see what the others do.

do you have the Visual C++ 2010 runtime installed? if not, that's why.

Yes, straight from the download link on the previous page for x86.

I looked through the error log a little, didn't spot anything that stood out.

I recommend getting the redist from the official source:

x64 here: http://www.microsoft.com/downloads/details.aspx?familyid=bd2a6171-e2d6-4230-b809-9a8d7548c1b6

Your link is wrong; it's for the 2008 redist, not the 2010.

2010 x64: http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=bd512d9e-43c8-4655-81bf-9350143d5867

Does that apply for the x86 one also, since that's what I was using to test the 32bit build he had?

[edit] I just checked, it was good for the 32bit Roll Eyes

Nice job, this is just my initial testing, but the 64 bit compile speeds up hashing by over 28% so far over the 32 bit counterpart.

So for example, my 8-core system does (600 khash/s per core = 4800 khash/s) for normally, but now averages 5700 khash/s

I'll certainly be sending some bitcoins your way Wink

I'll send you the first 50.0 it finds.
