hashkill - testing bitcoin miner plugin

[Keninishna]

Here is my output:


Adding the -D option gave me about 5 mh/s extra 

[gat3way]

Yeah and I can clearly see that "GPU drop" effect

Gotta be some synchronization bug, I will have a look at that...

[SkipDaShu]

Curious... haven't seen a compare between HashKill and the Diablo miner here.

[gat3way]

OK think I found what causes that GPU drop. Also pool failover coming soon. I also found a small bug that potentially caused more stales under certain circumstances. Will release soon.

Is your hasher optimised for the 5000 series? I seem to get get less hash rate (50+) and also less shares per hour.

[gat3way]

OK, new release is here. What's new:

* GPU drop problem should be fixed
* Added pools stats for btcguild.com. Use -a <apikey>
* Fixed a race condition situation which would submit more stale shares under certain circumstances
* Added pool failover support. It is enabled by using the -f <inputfile> option. You create a text file in the following format:

user:password:host:port
user1:password1:host1:port1
...

then you run hashkill like this:

hashkill -p bitcoin -f filename

The end-result would be that once there are connection failures to a pool, we switch to the next one in the list. No time wasted on reconnection attempts.

poclbm/phatk based hashers, specifically phoenix and diablo.

EDIT: Actually may of been GPU speed drop issues... ill keep an eye on the new version.

[gat3way]

What's your hardware, SDK version and catalyst version?

[kripz]

5770, sdk 2.4, cat 11.5. debian 32bit.

another machine same software but 5850.

See post #348, ill post back when i get an hours run out of it.

[gat3way]

Hm interested in results with the latest version.

[kripz]

Still having issues with flexible mining proxy. This is the only client that crashes.

Mining statistics...
Speed: 164 MHash/sec [proc: 18] [subm: 16] [stale: 0] [eff: 88%]
Long polling: got new block!
Speed: 159 MHash/sec [proc: 54] [subm: 39] [stale: 3] [eff: 72%]     [error] (ocl_bitcoin.c:141) Cannot authenticate!

Speeds dropping slightly, though this was only 30 minutes testing. I get 180mh/s constant with phoenix and diablo.

[gat3way]

You don't need to use the mining proxy now. The failover functionality is built-in already.

[kripz]

I'm not using the proxy for that.

Hi Get3way,

I downloaded your tool yesterday, it really increases my hashing rate about > 20% (from 193MH/s on an 960/1200 OC HD 6770 to 212MH/s).
However, it also increased stale share rate from 1% to about 6.5%. I'm currently mining @bitcoins.lc

Also I'd like to ask whether hashkill utilizes CUDA as available. Running an openCL kernel on an nvidia card would seem somewhat unlogical to me.

If you need more data for debugging, feel free to pm me, otherwise, great work, keep up with it, and I'm really eager to see the sources being released soon too!

Can't download the binaries -

Ditto

[Keninishna]

I was able to download and update and works great! except on one of my rigs one of the 6950s overheated past 109c!! fan was at 100% too. Usually it would turn the adapter off but for some reason it didn't. I'm going to RMA the card as it wasn't even overclocked anyways.

[gat3way]

Server had problems...it should be available now.

[antares]

hey gat3way,

I found that your nice tool stalls when it looses connectivity.
It would be nice if it could auto-resume connection to the pool if interrupted, as at least here in germany all internet connections are interrupted at least every 24 hrs - gateway vendors have countered this disconnect to fall into the night time, so the rigs are usually offline for some time every day which is uncool. It'd also be nice to have a socket spawn from hashkill that allows reading of basic program statistics, so we can develop our tools around yours. It'd also be awesome if hashkill had a switch to show all avail plugins - eg I've been searching for some tool that can use a GPU to get around salted MD5 ($1$, ya know:-D). Still the question remains whether hashkill has native CUDA support.
