OLD: BFGMiner 3.10.0: modular ASIC+FPGA, GBT+Strtm, RPC, Mac/Lnx/W64, AntU1, DRB

[JBT]

I'm mining both on CPU and GPU. For CPU mining I'm using cpuminer and for GPU bfgminer (3.8.1).

The hash rate in bfgminer is ~200 KH/s and for cpuminer it's 22 KH/s.

bfgminer has failed to solve a single block while cpuminer has found 20 so far.

What can be wrong? Thanks!

Also I've tried changing the intensity, but it doesn't work.

you are wasting your time doing CPU mining (7KH/s?) even GPU mining is a waste at 380KH/s

I'm not mining litecoins.

Besides I've multiple GPUs installed (4), but first let's fix 1.

You've solved 20 blocks with a CPU?  I don't think so.  If you had, you're either posting from 2008 and got 1000BTC for nothing, or you're the luckiest person alive, or you're reading the screens wrong.

I suspect what you're seeing is "New block detected" on the network, which bfgminer doesn't report (because it's pointless information).

[HellDiverUK]

I'm not sure you want to fix this, or if you want to support this.  I suspect it is not just PPC issue, all alts pools will have the same issue.

You can't run different blockchains at the same time.  BFG loads whatever coin's chain on startup, and won't change it, so you can't flip between BTC and whatever other SHA junkcoin

Maybe he is working on some early forked chain or something (doing solo).  I'm not sure if we've had forks early on.

I think he's just reading it wrong.

One thing I've noticed -- I tend to get hardware errors at the same rate as I should get blocks.

So it might be happening that whenever the GPU solves a block, it solves it wrong and triggers a hardware error.

It's working on good-for-nothing dieing alts for testing purposes. They've difficulty like 0.00x

Just wanted to put some official acknowledgement that HellDiverUK's response here is correct (mainly because I get asked it often).
This is clearly stated in the README since forever.
*gminer has never worked with multiple blockchains in the same instance.
Maybe some day I'll get around to rewriting enough code to make it work, but it's not really a priority.
If someone else wants to try to do this, I'll consider merging the code - but it's definitely far from simple!

Are you sure?

I kinda works for me with PPC and BTC chains. 

When I let PPC pool work for 15 minutes and then switch to eligius, eligius works ok.
After that I can switch back and fort between BTC and PPC pools.

The problem is the initial selection of the blockchain.  It seems the miner does not select the correct one for the first pool.  Which is understandable since it does not know the type of pool.
New pool "type" property?

Try it for yourself.  I looks like a bug to me.

Is it possible you implement stratum proxy for cgminer connections? I get H-not-zero errors and it looks like more people ran into the same. You would be a hero of a lot of people if you implement that

Thanks!!

This is a bug in cgminer. Any working stratum client can handle the proxy fine.

I'm getting 100% hardware errors on Linux.

Whenever bfgminer finds a block, it's hardware error.

I'm using an ASICMiner Cube.  BFGMiner 3.8.1 32-bit on Windows and 3.8.1 on OpenWRT. 

The Cube is reporting no Longpoll support when using BFG's getwork proxy, but does say Longpoll is active when using Slush's proxy.

Is Longpoll important? 

[inaltoasinistra]

I'm getting a lot of reject (30%) from eligius. I have a BFL SC 7GH/s, Arch Linux and bfgminer 3.8.1, What could be wrong? Thanks!

Lp is used to gve updates on blocks for the getwork protocol aka new block on network.

It shouldn't make a difference since bfgminer is just man in the middle to a stratum/gbt pool or node and those protocols let bfgminer know of new blocks and all other data through a single comm channel

GW used more than 1 comm channel
Strtm/gbt use 1 comm channel

I don't believe bfgminer is presently coded to take upstream new blocks alerts and pass them down stream to proxies. No need really. The work bfgminer issues will always be current block as long as the pool is.

Slush maybe coded to do the above functionality?

@LJR care to correct any falsehoods in my logic?

[Luke-Jr]

Previous Bitfountain (aka "ASICMiner") products did not support long polling, but it is certainly beneficial and perhaps worth adding to BFGMiner.

That would be great if you could - currently running the Cube through slush's proxy seems a little more efficient than through bfg's - but I'd rather use bfg.
