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

[flound1129]

I seem to have a problem where if I restart cgminer multiple times, eventually it stops hashing at full power and only does like 40 mhash.  Also, when this happens, my computer graphics performance takes a nose dive, the mouse starts jumping around, etc.

I am using win8 x64 with the latest AMD beta driver.  Anyone else having this issue?

Anyone have any clue why multiple people have noticed weird hashrate increases a few nights ago while using LTC in cgminer? See the posts here: https://bitcointalk.org/index.php?topic=260642.msg2789664#msg2789664

Apparently over the night a few nights ago, while tinkering with my 7970 (which was not performing as well as it should be, but it never has), it just decided to work while I was sleeping. Upped the hashrate from 522KH/s to >700KH/s (which it should be getting) for no reason. I checked it's status the next morning, and it instantly decided to go back to it's slow 522KH/s. Havn't been able to get it back up to the faster speeds since.

This wasn't just CGMiner mis-reporting the hashrate, either. The WU: rate was much higher than it had been. And other people have noticed similar issues. I'm not sure if their issue was the same night as mine, as I think our dates were 1 night off.

Any help would be appreciated. Thanks!

Totally bizarre, and apart from "maybe it was a cold night", I have no idea. Share submission certainly does have periods of higher luck overall and vice versa, but not the hashrate as you've described.

Anyone know what the changes are in this or anyone actually using next firmware from Avalon wiki

ckolivas any details on your next release for Avalon?

I'm still in Greece and will be for 2 more weeks. I had nothing to do with that firmware.

I'm running Raspbian on my RPi and got this error when trying to compile the api-example.c.

Code:

pi@raspberrypi /usr/src/cgminer $ gcc api-example.c -I compat/jansson -o cgminer-api
In file included from api-example.c:26:0:
miner.h:121:22: fatal error: libusb.h: No such file or directory
compilation terminated.
pi@raspberrypi /usr/src/cgminer $

I had previously done:

Code:

pi@raspberrypi /usr/src/cgminer $ sudo apt-get install build-essential git dh-autoreconf libcurl4-gnutls-dev libusb-1.0-0-dev libusb-dev libncurses-dev libudev-dev yasm screen

If anyone could help this linux noob, I'd appreciate it.  BTW - I suspect the answer is:
   sudo apt-get install <something>
but I have no idea what the something is.

On debian-derived systems you can install the apt-file packages to allow search for packages that provide specific files.

Your error message is about missing libusb.h. I'm not on a pi, but on my machine:

Code:

$ apt-file search libusb.h
apcupsd-doc: /usr/share/doc/apcupsd/examples/libusb.h
libusb-1.0-0-dev: /usr/include/libusb-1.0/libusb.h

Is there anyway I can include a comment in my cgminer.conf file?
I tried /* comment */ but it crashes.

I would expect something like "-I /usr/include/libusb-1.0" in the compile command. Maybe you need to re-run ./configure?

I tried /* comment */ but it crashes.

No.

You can put unused objects:
 "janssonsux" : "yes it does"
However, they will be lost if you write the settings back to the file from cgminer.

I tried a few variations but they all failed, e.g.
"url" : "stratum+tcp://pool1.us.multipool.in:3348" : " MegaCoin (MEC) ",

cgminer.exe: -c: JSON decode of file 'MultiPool_Miner_Aurum.conf' failed '}' expected near ':'

No, I mean you can put unused items in there:

"url" : "http://sendyourcoinstome.cam:3334",
"url_666" : "damn I hate json",

You can't break the json rules.

Oh, json rules, I thought you meant Jason sucks 
Works great, thanks.

jannson is the c library cgminer uses for parsing json.  And it is not wonderful

Hi, can you add into cgminer:
1) SHA 3 algorithm for mining CopperLark
2) time counter like in BFGMiner:

[flound1129]

Why does this happen?



In cgminer I have queue="1", why is cgminer continuing to submit difficulty 16 shares after the pool diff changes to 32?

This is in 3.3.1.

Anyone have any clue why multiple people have noticed weird hashrate increases a few nights ago while using LTC in cgminer? See the posts here: https://bitcointalk.org/index.php?topic=260642.msg2789664#msg2789664

Apparently over the night a few nights ago, while tinkering with my 7970 (which was not performing as well as it should be, but it never has), it just decided to work while I was sleeping. Upped the hashrate from 522KH/s to >700KH/s (which it should be getting) for no reason. I checked it's status the next morning, and it instantly decided to go back to it's slow 522KH/s. Havn't been able to get it back up to the faster speeds since.

This wasn't just CGMiner mis-reporting the hashrate, either. The WU: rate was much higher than it had been. And other people have noticed similar issues. I'm not sure if their issue was the same night as mine, as I think our dates were 1 night off.

Any help would be appreciated. Thanks!
