hashkill - testing bitcoin miner plugin

[gat3way]

I found that your nice tool stalls when it looses connectivity.

If you don't define a pool list text file (and use -f file) on connection loss, it sleeps for 20-30 seconds then retries. If you have defined a pool list file, it just tries the next one without sleeping.

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.

This is not supported, however the bitcoin plugin exports statistics in a text file in json format (in ~/.hashkill/bitcoin.json).

It'd also be awesome if hashkill had a switch to show all avail plugins

Use hashkill-gpu -p

I've been searching for some tool that can use a GPU to get around salted MD5 ($1$, ya know:-D).

MD5(Unix) is not supported at present on GPUs. It is on CPUs though. The only tool I know of that supports it on GPUs is oclhashcat+

Still the question remains whether hashkill has native CUDA support.

No CUDA support, just OpenCL. Yes, CUDA tends to be faster, but I don't really care about 5-10% performance gains on NVidia platforms that require the whole codebase to be rewritten. If it was AMD, I would do that, but NVidia hardware just sucks in terms of integer ops. It's a waste of money and electricity for hash cracking, even when huge hashlists are to be cracked.

Hi,

I've tried hashkill for the first time today, but unfortunately it doesn't quite work well for me (it works at 1/3 GPU capacity only):

Linux tifa 2.6.35-30-server #54-Ubuntu SMP Tue Jun 7 20:13:05 UTC 2011 x86_64 GNU/Linux

LD_LIBRARY_PATH=/opt/ati-stream-sdk-v2.2-lnx64/lib/x86_64/ hashkill-gpu -p bitcoin -f pools -D -G4

SDK version: 2.2
Catalyst version: 10.2

Any ideas why?

Edit: I use SDK 2.1 in my miners because 2.2 and newer for some reason don't work for me. And 2.1 doesn't work with hashkill, I get the clBuildProgram error.

Something's wrong with Fedora 14, 2.1 SDK and 4650. It used to work in some previous version.

Running under strace:

open("/tmp/OCL1Dtk0m.log", O_RDONLY|O_LARGEFILE) = 3
_llseek(3, 0, [19367], SEEK_END)        = 0
_llseek(3, 0, [19367], SEEK_CUR)        = 0
_llseek(3, 0, [0 ], SEEK_SET)            = 0
read(3, "/tmp/OCL1Dtk0m.cl(107): error: b"..., 19367) = 19367


Looks like the OpenCL compilation log contained more descriptive error. Maybe output that error when compilation fails?

[gat3way]

Any SDKs below 2.3 are not supported, sorry. They do not support OpenCL 1.1 features correctly and have significant problems with using multiple devices in a single process.

P.S if you chose to use 2.2 anyway, do not use -G4, but -G1. It should provide you better utilization.

@gat3way
ok, so I see that hashkill is supposed to resume hashing. however I had 3 occurrances of a stalled hashkill today, each correspond with connectivity issues(I monitor load on my GPU and I just added monitoring my IP addresses)

It'd be also nice if you could add a wallet ID to your signature so we can donate to you to keep you doing your amazing work.
Last thing for now - I'd like to set up a mirror for hashkill, so people wont get stalled in case your site gets anavailable again - If that's ok with you

this is what happens when hashkill gets killed.

Still slower than poclbm/phatk on HD 4650 and SDK 2.4:
hashkill 24Mhashes/sec
poclbm/phatk: 27-29Mhashes/sec

Interestingly minerd suffers from the same problem, with exactly the same hash rate numbers.

[datguywhowanders]

Has anyone tried this with either a 6950 or 6970, and if so, are they getting any gains over using poclbm or phoenix?

On my 6950 I see the same rates as phoenix/poclbm+phatk, +/-1MHash.

I tried latest release and the MH/sec seems faster, the problem is that I get 0% efficiency, with no good submitted shares.
I'm using SDK 2.4 and stock ati drivers from ubuntu 11.04, any hints?

Also, I would like to ask gat3way to please change the name of the file for every release because using the same name for different content causes a lot of problems for who uses proxy and makes difficult to trace the problem or benefits of every release.

Thanks!

[Dusty]

I forgot to tell that I'm using bitcoin.ls, and it's possible that the problem only exhibits with that pool?

[gat3way]

Don't know, need to investigate.

Unfortunately my priorities are now shifted towards implementing some DES-based password hashing algorithms on GPUs, so I won't be able to work on the bitcoin plugin in the near future.

[kripz]

open source it?

Great move, thanks!

Out of curiosity: is it possible to use hashkill to crack WEP passwords...?

[gat3way]

No.

Nice tool, but it cannot find one of my cards. I have two 5830s installed, both are being detected by Linux and ATI drivers:

Code:

Currently hashkill only detects the second card.

I'm assuming you have the device ID hardcoded somewhere?

Edit: Sorry, my bad. One of the card is detected by Linux but not by the ATI drivers. This is definitely not hashkill's fault. My apologies. Thanks for the great tool again.

Nice tool, but it cannot find one of my cards. I have two 5830s installed, both are being detected by Linux and ATI drivers:

I have one mobo that does this with it's 2 x 5830's.  One boot only card 2 and only video on card 2 (even boot up bios screen).  One or two reboots and video moves to card 1 where it should be and Diablo can then use both cards.  Seems that something gets messed up on a soft reset.  Power off for 3 mins and it always comes up right.

I have another very similar machine, same OS, same drivers, same config files, both i7-87x 1156 sockets, different mobos and it never does this.  The one that gives me the problem is a MSI H55-GD65 (H55) the one that doesn't is a BioStar T5 XE (P55) mobo.

My understanding is that the bitcoin plugin isn't included in the source code drop. Am I wrong?
