Modular Python Bitcoin Miner - Official Thread

[shad]

Status update on my miner:

1.) i always wrote that i am mining on ARM, thats not true sorry for that
i checked cpuinfo and it's an "MIPS 24Kc V7.4" with 128MB-RAM with one X6500
OS: Openwrt
RAM-Usage:56MB

2) MPBM stop working today (after i added an additional pool and made some config changes) with some "OS error can't handl memory allocation or something"
i am on version 0.1.0 (beta), yeah its at this version since a long time, commit "7690b2e" (Apr 27, 2012)
it did run stable for 2 Month 16 Day
This Miner-Software is great!

3) i added a 2. P2Pool today and i am working with priority's, so the 2. P2Pool with prio 1 (which is lowest afaik) gets the most Hashrate, after searching this thread i came to the post where it is noted that P2Pool should run at an other Blockchain but that isn't implemented yet? i didn't look at the code but i guess it would be a bigger implementation and i am thinking about a simple solution

there are only 2 blockchains => Bitcoin and P2Pool, i guess nobody is mining namecoin or others without merged mining
so i am thinking about an "workers source"-option called "new block doesn't effect other worker sources"
made a git pull yesterday and my problem is gone nice work

just my 0.5BTC

Hi, I hope this is a good place for bug reporting.

I have been using MPBM for a few days now, cloned from github on 26-September.

Over the weekend I left it running, and left the Safari window open with the WebUI running.

When I returned today, it was running real chunky, and Safari was using several gigs of memory.  Upon closing the MPBM tab, the memory was freed and things returned to normal.

I think the AJAX code is leaking memory.  Here is a screenshot of the Activity window after it has been running for a few minutes:



I think either the getallstats responses, or /api/log/stream (or both) are continuing to accumulate in browser memory for as long as the tab remains open.

Sorry I didn't capture the Activity window before closing the tab earlier.

Let me know if I can do anything more to help debug this.

I regret to report that after several months of using a very early version of mpbm (v0.0.4alpha) I can no longer get the miner to work with my x6500 and BTCGuild using today's git version (v0.1.0beta)

I have set up everything to the best of my knowledge but I get right of the bat:

Never mind. I was entering the wrong user_worker and password.

Perhaps a less cryptic message is in order here.

Does anyone know why using both BFL singles and Icarus FPGA miners with MPBM does not work? Is there some special trick that has to be done? Oddly even when I go to add a worker the bfl single worker does not even show up even though it appears the appropriate modules are there in the modules directory. I tried even the latest github build, no go. Eventually I gave up and used bfgminer for the singles and mpbm for the icarus boards.

How do I use this with the ModMiner Quad? I currently use BFGMiner, but I prefer the webinterface of MPBM. It works great with my X6500s, now I want to add in my MMQ.

How do I do this?

[allinvain]

Is this project still being worked on or has it been abandoned? Any chance of updating the software to support the stratum mining protocol and any of the recent advancements in bitcoin mining - perhaps even support for ASIC miners? (granted being ASIC ready means supporting a mining protocol like stratum or getblocktemplate - luke's idea)

[shad]

i guess you have to use the stratum-proxy, which is impossible for me on my router but it should work fine on a pc or a raspberry

but i am pretty sure it will support ASIC
last update was 17 days ago

[freshzive]

just did a git pull and noticed stratum support. seems to work fine with my set of x6500s. cheers!

[fpgaminer]

If anyone has trouble using MPBM's Stratum Work Source with the BitMinter pool, I made the following patch against the latest version of MPBM:
http://pastie.org/6112329

I have the patched code running well with the Stratum sources of Slush, BitMinter, and Ozcoin. On my Raspberry Pi and X6500!

Is it supposed to look like this, lol? Help!

Is it supposed to look like this, lol? Help!

Try Chrome/Chromium (this is how it looks like on Firefox).

Try Chrome/Chromium (this is how it looks like on Firefox).

I refuse to install Chrome (AKA Google Botnet) since it's a massive security hole and records everything you type into the URL bar. Opera is my main browser due to the tight securty options but the console log never shows up in it.

Aren't all browser recording what you type to make it easier to find later?

I can understand Chrome being a privacy problem being closed-source and configured to send back information to Google by default but I'm not sure how it is a security problem and why Chromium would be a problem at all given that you can check for yourself that it doesn't have any back-door or send data back to Google (which isn't possible with Opera unless you disassemble it).

Anyway, Opera is switching to WebKit (already used by Safari and all Chromium derivatives) so you may just opt to wait.

or try safari it works too
i use it only for that, and only because its preinstalled on osx

anyone else having trouble with stratum?
worked fine for some hours

now it is finding share but no accept or reject message, not counted on the pool

I've been plauged by this issue and today I've gotten a new issue and can't get my miners to mine at all.

Which cables did you end up trying?

Using bfgminer 2.10.5 for 2 weeks now without issues. Was using MPBM before because the x6500s had SICK/DEAD issues with older versions of bfgminer.

OCL 0 & 1 = 6870s (underclocked to 775/300)
OCL 2 = 5850 (overclocked to 960/300)
OCL 3 = 5670 (overclocked to 1000/300)
BFL = 864 firmware
XBS 0 - 3 = x6500 rev 3
