OFFICIAL CGMINER mining software thread for linux/win/osx/mips/arm/r-pi 4.11.1

[Zich]

I am having problems compiling the newest version with -enable-avalon activated.

What's with this file located here in the avalon folder?
http://ck.kolivas.org/apps/cgminer/avalon/20131116/

How I am supposed to use this file bin?

openwrt-ar71xx-generic-tl-wr703n-v1-squashfs-factory.bin

Thank you.

That was image for flashing TPLINK TL-WR703N with openwrt.

I wanted to get out one last good new avalon firmware before these devices become irrelevant due to rising difficulty:

http://ck.kolivas.org/apps/cgminer/avalon/20131118/

I finally tracked down the regression that was preventing the avalon from being reliable with the newer versions of cgminer and have built new firmware based on the latest cgminer 3.8.2 git checkout 390ac7062663c688b656cf0dc893163cd7a852b3

Thank you, was able to resolve the usb in use issue.

[RoadStress]

Anyone else with BitBurner noticing random full stops in hashing? Only noticed on 3.8.2. Will try with 3.8.1 and will update here.

Thanks con!
3.8.2 running stable for ~ 2hrs now, looks like a slight increase in hashrate and WU with smaller memory usage... still at 127% since starting.
Very nice!

From the looks of the info I would note that no shares are sent successfully to your localhost. I wouldn't think the work was intentionally discarded being high enough for a block. Possibly the difficulty calculation was a little off. I know more knowledgeable people can tell you for sure. If you run with --no-submit-stale it could cause this.

I am not 100% sure as I don't mine locally at enough hashrate to ever make a block.  Well that isn't technically true but I currently am only gambling on the results locally.

Are you attempting to mine something not bitcoin, and are you on the latest version?

[lano1106]

must be on testnet.

Some devs on the bitcoin mailing list were complaining recently that someone is spamming the network with an insane number of new discovered blocks!

AMU10 has gone zombie about one hour in to a 3.8.2 run.

Hot-swap did not fix it, but Q and a restart did. (Win7 64 zipped version).

I believe I've finally found out why they weren't hotplugging again, and it would affect any operating system, not just windows. I have committed a fix for it into master git, and here's a binary to try out:
http://ck.kolivas.org/apps/cgminer/temp/cgminer-undead.exe

Is there a patch I can add to my 3.8.2 RPM?  Or is a new release impending?

I can find the diffs on github: https://github.com/ckolivas/cgminer/compare/v3.8.2...master
But there is no button I can see to download in diff format.  Does github (as opposed to git cmdline tool) really expect you to retype the changes?  

SOLVED: secret API - append .patch to URL

Hmm, the changes to 3.8.2 seem to concern avalon, and I have Icarus.  So it likely won't help me, but I'll give it a try on next restart.

I have 4 USB ASIC Miners, which cgminer detects at Icarus.  It runs for 2-4 hours before half the units are disabled with a message like the following:

 [2013-11-18 17:49:20] AMU 4 SendWork usb write err:(-7) LIBUSB_ERROR_TIMEOUT
 [2013-11-18 17:49:20] AMU4: Comms error (werr=-7 amt=22)
 [2013-11-18 17:49:20] AMU 4 failure, disabling!

For a while, the failed units are discovered again via hotplug:

 [2013-11-18 17:49:23] Hotplug: Icarus added AMU 5

But hotplug eventually fails to rediscover failed units.  However, restarting cgminer does rediscover them.

Yes that's the issue I posted about earlier that is only in the latest git and not in 3.8.2. Some zombies would never be resuscitated.

I don't know if it's me or not.
Unzipped latest version of cgminer, and tried running cgminer.exe with --scrypt and it comes up with unrecognized parameter ?

Went back to 3.7.2 and all is fine. Can't seem to mine LTC with 3.8 c:

I think you missed this a few pages back... https://asktom.cf/index.php?topic=28402.msg3538435#msg3538435

We discuss it further here:
https://forum.litecoin.net/index.php/topic,6925.0.html

Others are going to pick up the pieces and continue development here: https://forum.litecoin.net/index.php/topic,6994.0.html

Seems that the cgminer README doesn't updated with this information.

...cgminer doesn't support litecoin nor scrypt nor GPUs so there is no need to say anything about them in the documentation.

cgminer doesn't have a word processor built in, nor does it play videos.  Should those be mentioned in the README too?

Please note, the documented change was in the documentation, but it was in the file named "NEWS" along with all the other news about various changes made to cgminer:

Code:

Version 3.8.0 - 10th November 2013

- api update version to 2.0 and remove GPU form API-README
-Remove now unused scrypt files.
- api.c remove all GPU/gpu references and correct code as required
- Rudimentary removal of GPU OpenCL and Scrypt features from api.c
- Reorder configure alphabetically for devices to compile and fail if no support
is selected to be compiled in.
- BaB update/format some comments
- BlackArrowBitfury early GPIO V1 driver
- Fine tune the reading of results in bitfury driver to not lose any across work
restarts or corrupt due to store results not parsed during restart.
- Send a zero length packet at the end of every usb transfer on windows in case
libusb internally has batched them into one maxpacket sized.
- Framework for ntime rolling, keep looking for OP_USB_INIT replies when other
packets received
- Configure source for a new BaB driver
- sha2 allow external access to some macros and the K array
- Fixed a math issue when reporting fan speed on the status line.
- Use the main hashlist to store work done in the bitfury driver and remove work
from the list by time, thereby fixing the duplicates at startup. Count hardware
errors for when no match occurs.
- Add a get and queue helper work function.
- Remove GPU mining code.
- Use libusb's own zero length packet support unless we have to emulate it on
windows since only libusb knows for sure if it's needed.
- Unlock the avalon qlock while sending tasks to not hold the lock for an
extended period.
- Sleep in avalon send task on return to the function to allow other code to
work during the sleep period.
- Send zero length packets when terminating a usb write aligned to
maxpacketsize.
- Do the driver flush in avalon code lockless since it can lead to deadlocks.
- Reset the work_restart bool after the scanwork loop in case the driver flushes
work synchronously.
- Only check for the stratum clean message if we have had a valid message.
- Get rid of the stage thread since all work can be asynchronously added now via
hash_push anyway.
- Remove the now incorrect faq entry regarding scrypt difficulty.
- Check for fatal read errors and break out of the read loop in avalon.
- Send errors are basically fatal in avalon driver so break out of the send
tasks loop.
- Make the avalon driver return -1 for hash count when usb fails, allowing the
main loop code to send it the shutdown flag.
- Break out of the hash work loops when a failure is detected instead of
dropping into mt disable.
- Use usbutils' own ftdi parser for avalon and the ftdir's own latency for
managing timeouts since we can wait on reads with completely asynchronous
reads+writes.
- Use usbutils' own cps function for slowing rate of usb writes on avalon.
- Fix build for no libcurl
- Check length before submitting sync transfers

Are you attempting to mine something not bitcoin, and are you on the latest version?

Code:

./cgminer  -V
./cgminer: /usr/local/lib/libcurl.so.4: no version information available (required by ./cgminer)
cgminer 3.8.2

with rotate to other alt coins (PPC, ZET)

edit:
now I have uncommended
testnet=0
perhaps this is necessary in bitcoin.conf

As predicted, and that's unsupported.

Getting hex2bin scan fail.

What happened to cgminer-nogpu.exe in 3.8?
