1  Alternate cryptocurrencies / Altcoin Discussion / Re: [XPM] Working on a GPU miner for Primecoin, new thread :) on: September 04, 2013, 01:06:48 PM
I'm getting "The procedure entry point clEnqueueFillBuffer could not be located in the dynamic link library" and crash. Win8 x64 & GTX 560

You need to upgrade your amd/nvidia drivers to fix that one, but it will probably still crash after that.

Same here on Win8 x64 Nvidia C2075. The driver was updated in July and should support  openCL 1.1

You assume clEnqueueFillBuffer works in OCL 1.1

So I am seeing something that I find very strange.  Quite a few users have almost no shares at all, but have a huge share value.  Now since the most points that you can get from a share is 100 - and that is for an 11 chain which is very rare.  More likely you would get 80 or 16 points for a block.

If you are user xpm12 with 79 shares and 704 points, that means you must have found at least 7 blocks in the last 80 blocks that were found.   Yet when I look through the last 6 pages of blocks that were found, user xpm12 has not found any of them.  That doesn't seem right.

Then take user ssfnwfn with 84 shares and 542 points.  Same thing, but at least 5 blocks right?  This looks a bit better because ssfnwfn found one in the last 6 pages.  But still seems very odd.

Take a look at other users with thousands of shares and they have a much more reasonable ratio of share count to share value - and have actually found blocks.

This started happening a few days ago - well at least I started noticing it a few days ago.  Have people found a way to cheat the pool?

The new experimental miner that came out a few days does not report Shares, only ShareValue. (Unless you find a 9-chain).

While i don't know for sure, looks like he was running something like that.

Hello all,
I am posting this news on behalf of rdebourbon (of ypool.net fame).  He is in 'n00b jail' on bitcointalk and cannot post this message himself.


I am very pleased to announce my new beta version can be found @
https://www.dropbox.com/sh/zij7j205ucsmj3n/9ZtyXFSWu0


This is an optimized version of Mumus 7.1 build with my sieve updates and a few other performance increases. Block rate should be as good as / better than Mumus. Use same as you would Mumus V7.1

Please send feedback via yPool chat/messages.

Normal disclaimers apply. Use at own risk. Blah blah..

Donations welcome and appreciated:

BTC: 1Fph7y622HJ5Cwq4bkzfeZXWep2Jyi5kp7

It's gonna be hard to trust this...

I also use this build. Works very well. My i7 got its first block on it in > a month with it.

Hmm, on ypool block statistics ( http://ypool.net/stats.php?a=bd&nr=3981 ) the user

Quote
mumusv6miner   15517   4521.7   0.69676

how he got 15k shares in one block that took less than 2 minutes to be found? he's have the biggest share count in ypools...
something special of his seting??

Fishy?

v4mumusminer 18083 5000.9 0.755724
mumusv6miner 14510 4928.9 0.714749

Remember, shares count for 40 blocks...

Thanks mumus! I've got v6 working on all of my machines, from initial testing it looks like 6/7 ch are significantly higher but won't know for sure until its been running for some time. I tried AVX on Windows 7 with an i5 3570k and got the msvcr110.dll mentioned above, installed the Visual C++ package and don't see the error anymore but it force closes on startup Sad

Is it possible to run the AVX version on Ubuntu? I tried it with an i7 3820 but get the msvcr110.dll error, not sure how to fix this through WINE.

You just need the msvcr110.dll from the visual studio 2012 update 3 runtime.

I concur, yall are more than welcome to pull the source from https://github.com/hg5fm/jhPrimeminer and compile it yourself.

Sorry to say but this is a scam. I was running this for an hour, actually found a block but the block was not recorded under my name. Wonder where it went:(

define "found a block" I've been mining for 5 days and havn't found any blocks, but still managed to pull down XPM (and even withdrew it just fine).

Also, note I didn't release a 5-x64-sse2, that's what mumus released. Same with the 4-x64-sse2. These are simply alternate compiles of the same code that he already released.

From my personal testing, I have not found the avx build to be any better than the sse2 builds.

I noticed my Xeon E5-1620 runs better with -4, -s 600000 and -d 16 vs -t 8 -s 2000000 or 1500000 and -d 8.
Can it be that Hyper threading hurts mining performance?

My i7-2700K runs better with -t 4 than -t 8. Thermal throttling at t8 forces it to downclock for one, the PPS remains nearly the same.

Hello, my name is Elf and I am in Newbie Jail. I wanted to help some XPM guys out, but sadly, i've been restricted to this "place" where half the threads seem to be completely spam and even promoting ponzi schemes (ya, love it).

Hopefully i'll be released from newbie rehab and allowed to participate in "the real world" Smiley

Toodles.
