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

[-ck]

New release: 3.3.2, 10th August 2013

Cairnsmore1 (yeah. I know...):

I have hold off to upgrade to 3.x from 2.11.3, but today the temptation was too big ;-)

Upgrading etc. all went fine on Ubuntu 12.04.2, worked through the READMEs, did the libusb-1.0.16-rc10, disconnect USB, removed all --scan serial (ttyUSB*) from config file, restart everything, reconnect USB, did NOT issue the modprobe command...

Out of the 6x CM1s, cgminer only detects CMR0, 1 and 2. I let them run for a while with no problems, but of course I'm missing the rest of the boards.

Anyone tried the latest version with CM1s? Any other pointers?

I've tried, bo no luck
On my rig i'm using cgminer for icarus, lancelot, AMU, and bfg for CM1.

Sorry, neither of us developers own one and can't do anything about it, though we'd happily take patches from someone who does have one and wishes to update the code (so long as it doesn't break anything else).

I still have no CM1 ... get me one and I'll spend the effort to write a new driver to fully support it ... it requires a unique driver different to any other due to the chip it uses and how it uses it.

I personally support BitBurner, Lancelot (BlackArrow + Standard), Icarus, AsicminerUSB, BFL FPGA, BFL ASIC and ModMinerQuad coz I have them all, so I can support them.

Simple relevant example: the changes I made the other day, to the Avalon code, for my new BitBurner board meant that no Avalon would work any more.
Fortunately, ckolivas paid a ridiculous price necessary to get an Avalon a while back, and tested the change on Avalon and found the problem - that I then fixed.

The Icarus driver should find one FPGA or FPGA pair and mine on it - but I've no idea for sure coz I don't have one.

If some change either of us makes has any effect on that, well ... good to know, but no I don't have one so I can't test it.
I have no hardware incentive to do it, even though I wrote the first proper software support for the first CM1 (Yohan's team simply changed the baud rate in the Icarus driver and did nothing else)

Yes hearing the same old comments about the CM1 are ... the same old comments ... pointless, so do something about it.
Pretty soon it wont even be worth my while to have one ... so then there would be no possible incentive to work on the driver at all.

3.3.2 was showing funny results for A:X. Looks like it was adding the first nr of the Diff

Code:

[2013-08-11 21:37:04] Accepted fec59856 Diff 129/128 GPU 0 pool 0
[2013-08-11 21:38:20] Accepted 00cb02e5 Diff 242/128 GPU 0 pool 0

I switched back to 3.3.1

Edit: Looks like you made that on purpose Don't really like it

[rocks]

I've looked through the FAQ and SCRYPT-README file, but could not find an answer to this.

If I run the following with version 3.3.2, the following error comes back:

Code:

cgminer --scrypt
cgminer: --scrypt: unrecognized option

Every thread I found from Googling says to recompile the source in linux and enable scrypt. However I am using windows and can not rebuild.

Does anyone know where to find a cgminer binary for windows with scrypt enabled? I would have thought it would be included in the standard build.

Well, 3.3.0 is in my cgminer-binaries (as listed in the first post)
https://github.com/kanoi/cgminer-binaries

I just added 3.3.1 in there now also.

I added 3.3.2 yesterday, however, the 3.3.2 in my cgminer-binaries doesn't have the updated windows zip file unfortunately ...

3.3.0 worked fine, thank you

3.3.2 just cant load my config file anymore. Seems to be issue with int 19 and 20 (wont load it but still can set it). - Any way to avoid Int limit and to make newest cgminer to load file again?

Additional there is an issue that after a few days the application freezes (like crashed now new block etc., but no error or so by ati driver or os; just freeze and does nothing) <-- is this a known issue? Any fix?

Add --scrypt to your command line. 3.3.2 added a sanity check for intensities, which currently isn't detecting scrypt mode if you are setting it from the config file.

thx but:
cgminer-3.3.2-windows\cgminer.exe --scrypt --config C:\Users\mining12\Desktop\cgminer.conf <--- does not work

huh it does work... still means error in config file but then works
However this max int setting limit is kinda retarded; it would be cool to let miners the freedom.

Don't run cgminer out of a folder on the desktop.  You run in to Windows permissions issues, which can bugger up cgminer.

Move the cgminer folder to the root of a drive, and run it from there, it'll work.

Will try

Site maintenance is over, site is back online.

Git users may want to download the latest git version. There are some CPU usage improvements for both stratum and GBT that make a big difference when mining at ASIC hashrates on p2pool.

[seriouscoin]

Guys, can you guys explain to me why CGminer use lots of CPU power while mining with BFL ASICs compared to BFGminer?

I'm using RPi as a host and the difference is absurd.

60GHs SC with BFG miner uses ~5% while CGminer uses 20%

Anyone please test to confirm this. I have tested with different rigs and setup. Same result.

2 things.

In literally the very previous message to the one you just posted you'll see that I've committed changes that decrease CPU usage. Low power devices running asic hashrates is new so this issue has only recently showed up, and I've aggressively started optimising that now. The CPU usage is lower now and a new version will be noticeably so on these low power devices.

The second is that because there is no driver between cgminer and the USB device, all the CPU usage that is normally attributed to the driver and/or hidden from the user is now all shown as cgminer CPU time - this won't go away but doesn't mean the system is using more resources, they're just attributed differently.

Ck- Thanks for the update. I'm thankful you do still support the GPU miners, and a donation is long overdue from me, as I have been using your app a couple months now and it's beyond valuable.


On a side note, this isn't really a bug, but very important to stress, you MUST have the --scrypt statement prior to the --intensity 20 (or anything above 13) with your new version, as you added the intensity lockdown for non-scypt logic. This caused an issue in an app I'm trying out that passed the --scrypt statement at the end, so it wouldn't allow the --intensity of 20, or anything above 13, until I moved the switch before the --intensity statement.

Again, not a bug at all, as you would think --scrypt would come first anyways, but just a heads up in the event other apps might not watch the order in which they pass switches.

If you have been GPU mining, you've always been using his app ... no matter what name it has

I have an Issue with 3.3.2 and 5870 cards. It makes HW errors. (same clk as worked without err 3.3.1)
I am pritty sure that its not a HW issue, since HW err are also when downclk.
I use: TC 5760 I 19 Driver 12.8

Having some very odd issues with the recent version. My "Accepted" count is incrementing by 256 for each block.

I'm sorry, I missed that one. It seemed like an odd change to me, so I just assumed it was taking the wrong value from somewhere. Thanks for pointing it out.


P.S. - Sent a small thanks to your 148KkS2vgVi4VzUi4JcKzM2PMaMVPi3nnq address for all your work on this in the name of GPU miners.

You are not alone with that. I can't really see the point of changing that but it's cons decision.
