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

[-Redacted-]

EMC uses GBT, so --request-diff should be working for you in the current version of bfgminer.

Does that mean that if the pool I use selects say difficulty 3 for me and I can use the request difficulty function to reduce difficulty and therefore increase my share percentage/increase btc income ?

You'll not be making any more money.  If you submit diff 3 share, it is the same as submitting three diff 1 shares.
Dynamic diff implemented by most pools is to limit network traffic, detect fast miners and send them less but harder shares to solve.

What we are talking about here is the minimum difficulty the pool will offer. 

Problem I'm having with mini rigs is that when they connect to a pool that starts off with diff 2 (and does not allow me to raise the minimum difficulty), miner starts off hashing tons of diff 2 shares, then pool slowly adjusts diff to 300 or higher, and (somehow) all the diff 2 shares that were calculated become rejected (unknown work).  Not sure why, but that is what I see.  Sometimes a pool might drop the diff back to 2, due to a bug or network disconnects, and fast miners start the process again from diff 2 back up to 300-400s.

If I can set the minimum diff at the pool (using EMC at the moment, and it does not offer this option) or in the miner, I could avoid the problem of adjusting the difficulty level.

Telling a pool: "Please send only diff XXX or higher shares"  would manually speed up this negotiation.

I think this feature might become more important as more ASICs are deployed.

Gotcha.

Makes sense now I think about it.

Thanks

What is this error <job '2116' not found> ?

Also, download link doesn't work.

I just had 2 instances of "fragmentation fault. Core dumped."  On restart from the first instance I noticed a few [NULL] lines in the share submissions shortly before the second fragfault.  I rebooted at that point and have had no more dumps in the past hour.

Running Ubuntu 13.04 on 64 bit AMD quad core processor with 4 Gig of RAM.  BFGMiner is the only thing that has been running on this machine for the past week.  Maybe it was just time to re-boot.  The only thing different today is that I shut down bfgminer and added 4 more usb eruptors and a new usb hub then restarted.

Will see if I can find the core dump if that will be helpful...

I've updated the download links with Eligius's mirror. Hopefully my server will be online soon :/

--request-diff only works going up, not back down; and is used as a means to lower TCP/IP network chatter and bandwidth by Rasing the difficulty that your miner accepts as shares

It asks the pool for a specific difficulty. The pool can decide to oblige, ignore, or do the opposite.

What is "BW" in bfgminer?

Bandwidth.

Sent my buddy a USB Miner to start mining... He's getting an error, "Do not have user privileges required to open //com1"

I'm not familiar with that issue... Any quick suggestions?

I usually get that when the driver failed to initialize the device or whenever I forget to turn on my internet connection.

While I'm on here, can anybody please tell me how to increase the default console size to full screen and show all my miners by scrolling through them.  For the life of me, I couldn't figure it out.  I'm a BFGMiner as well as a CLI console virgin, BTW.

[SirMintALot]

right click on that window, choose the last option (I think its properties in english), then go to layout. There you can change window size and position. When you restart bfgminer it will use that new layout.

Thanks for the reply.  So, it was the "restart" that I missed.  It drove me batty  .  Thanks again.

BFGMINER works without having to install the drivers right? Isn't it plug and play? Been a long time since I set mine up... There also is most definitely an Internet connection.
