OFFICIAL CGMINER mining software thread for linux/win/osx/mips/arm/r-pi 4.10.0

[techman05]

It's not just --enable-hashfast? Run through and compile others and see how it's named in the list above the command prompt. I'm pretty sure it's in cgminer.

You're missing the ncurses development library when building it.

Hi, my mining rig is composed by five "towers", each one connected via a USB cable to a Windows PC:

1x5 Canbused Bitburner Fury boards
1x4 Canbused Bitburner Fury boards
1x4 Canbused Bitburner Fury boards
1x1 Damaged Bitburner Fury board (hashes half speed/usb only)
1x1 Damaged Bitburner Fury board (hashes half speed/usb only)

So far I am using one instance of CGMiner with --avalon-auto and so far so good, the rig mines with no problem at all.

As I do not know how work is handled internally by CGMiner I was wondering if mining performance may be hampered by the bad boards working together with the good ones.

Should I run two separate instances of CGMiner? One for the good 3 towers and one for both bad towers ?

I am having trouble compiling cgminer, pretty much any version from the past few months on either Mac OSX 10.9 (Mavericks) or 10.6.11 (Snow Leopard) I am using the Mac ports collection for the dependencies, and I was able to comilpe a few months ago but can't anymore, so something has changed.

The error I get is:

Code:

Using gcc 4.8, but also tried earlier versions.

I know there are pre-compiled Mac binaries around, but I would rather conquer this problem, obviously someone has.

Any suggestions?

I am using latest cgminer to solo mine on testnet and I think there is a bug with handling the testnet difficulty. After no block for 20 minutes, testnet difficulty drops down to 1.0, but cgminer still requires work of previous (high) difficulty (12.3K now).

>bitcoind getwork      returns "target" : "0000000000000000000000000000000000000000000000000d54050000000000"
>bitcoind getinfo       returns  "difficulty" : 1.00000000

Is this a bug in cgminer?

Hi I see there is support for nf2 and nf6 could you add support for nanofurys devices that are chained together as I have 5 nanofurys chained. And also to set the bit speed of each individual bitfury chip. This is possible in bfgminer

Thanks
Paul

Usual story with hardware I haven't seen before: I'm happy to take patches, but I cannot write the code to support them without the hardware myself or suitable sponsorship.

ckolivas I would really appreciate an answer to this question.

As far as I know this is not something asked before and could prove useful to other Bitburner Fury users too.

I don't have one and didn't write the support so not sure (maybe Kano can help). Generically separating dud hardware from good is always a good idea.

Hi,

Having a small problem with Cgminer 4.3.3 and Blackarrow bitfury boards.

Every so often I get a (duplicate) share that is indeed a dupe of a share just before it.

I changed line 529 from #define BAB_WORK_EXPIRE_mS 7800 to 5800.  This seems to have helped.

Any suggestions?

Thanks!

Edit: My pool is Eligius.
Edit#2: Line 529 seems to have minimal effect on "dupes".
No one has any ideas?

New release: Version 4.3.4, 25th May 2014


Human readable changelog:

- Driver updates to spondoolies, cointerra, avalon2 and minion.
- Support for nanofury NF2 (good working) and NF6 (flaky, ?design related) USB sticks.
- Extra output in the API for NF* devices and BXM in the API for per chip information.
- Fix for pools going idle if stratum is restarted unsuccessfully.
- Fix for a crash in libusb when devices are frequently plugging/unplugging on linux.
- New benchmarking code with the --benchmark option which uses a deterministic set of work items to find a known number of different diff share nonces at regular intervals. Note that devices that don't check the entire range (mainly bitfury based devices) will not find some of these nonces so the benchmark code is suited to devices like the hashfast,  cointerra etc. Give it an hour before assessing results.
- Fix the reset counter on hashfast devices to be properly inherited.
- New ruby example for API.
- Low level code fixes and cleanups.


Full changelog:

- Add support for 2 nonces per block in spond driver
- Increase timeout on reset in cta driver to 5 seconds
- Increase max diff on spondoolies driver slightly to be well below spi comms
limitations
- Use the active contents lock and safe list iteration within the linux usbfs
code
- Add Ruby Api Example
- Automatic detect the small miners
- Update default modules from 3 to 4
- Fix the temp max. we should use currect max temp
- add avalon2-cutoff options
- Enable the cutofftemp to Avalon2. ignore longer coinbase and longer merkles
stratum
- Fix the diff value used on MM firmware
- Mark pool as idle if stratum restart is failed
- Add hacky workaround for double list removal race in libusb
- Make the work given in benchmark mode deterministic on a per-device basis
- Rework the benchmarking code to use a deterministic set of work items with a
known number of diff share nonces at regular spaced intervals
- minion - restrict nonce read result size to ioctl() limit
- minion - must check temp when overheated
- minion - idle chips that hit >100C until back to 80C
- minion - report the chip/reg when aborting due to an invalid ioctl() size
- minion - all freq in Mhz but only convert when used
- minion - remove unused ioctl debug
- minion - command queue is now larger
- minion - check rolled in stale work cleanup
- Work stats should be based on device_diff not work_difficulty since non-shares
haven't been filtered out yet
- Prevent a segfault when writing a config file containing 'rotate' option
- minion - comment out HW debug message
- minion - roll work to reduce CPU
- minion - report init_freq in stats
- api - howoldsec is only used for USB
- minion - allow setting the frequency
- minion - disable iostats by default since it slows down mining
- minion - define frequency value table
- minion - report temp/cores/freq and handle temp formatting
- minion - item is undefined
- Rationalise diffs stored in the work struct and document them to avoid further
confusion
- Add basic API stats for nfu drivers to see how many submits each chip returns
- Add output direction for the EN0 pin on nfu driver
- Support power management optimisations in newer nf* firmware
- Support variable numbers of chips with NFU and BXM drivers
- Identify number of chips in nanofury devices and change name accordingly
- Rename nf1 driver to nfu in anticipation of support for more chips
- Make hashfast reset counter rise on old instances when inheriting the value on
new ones

I'm still using 3.4.0 on a BeagleBone to run my BFL Jalapeno 7 GHs.
An oldie but a goodie.

Are you maybe using load balancing or too low of a difficulty. I only get problems when I switch pools or exit and come back before it knows I 'm gone.

Dups are expected.
I get quite a lot and I wrote the driver
Expiring the work earlier risks rejecting valid work.
The interface to the chip makes it difficult to ensure you aren't rereading the same results sometimes.
You may have noticed the low HW error %?
That's due to using more CPU and sometimes getting dups.

I've been working on the AntS2 driver and wrote a simple dup check that I can implement in any driver with a few lines.
Once I've finished the AntS2 and the updates to the BlackArrowMinion work soon, I'll probably add it to the BaB driver also, since I see the dups also - and avoiding sending them to the pool is nicer to the pool and saves ever so slightly on network usage.

Oh well about your choice of pool ...

FYI: I've got 7 boards on a V2 4 SPI controller always above 270GH/s
The code works well up to 8, but will need some SPI tuning to do more than 2 per SPI reliably.
Mine runs forever without failing - only restarts on power outages, config changes or cgminer updates.
1.25W/GHs at the wall, really is pretty amazing for these boards that have been around for so long!

THX for the new version, i will test and report

If your asking if CGMiner works with 32 bit Windoze 7?  The answer is yes.

I mean, I often fail to use it on win 7 x86,
and if you can help command for maximum performance?

Hmm, works fine for me.

There is no command to maximize performance for my setup, which is USB BE's and a Jalapeno.  I just run CGMiner with the  pool stuff and it detects and sets everything for me.

Im running 3x Bi*Furry on powered USB HUB - power is sufficient.
Randomly (after 10m - 4h) I get:

Code:

BXF 2 BXFWork usb write err:(-7) LIBUSB_ERROR_TIMEOUT

and miner crushes (WIN 7).
Any idea?
