Guys what i'm doing wrong...
git clone https://github.com/sp-hash/ccminer.git
./autogen.sh
./configure.sh
everything is fine here.
but when i try to make:

Code:

/usr/local/cuda/bin/nvcc -gencode=arch=compute_52,code=\"sm_52,compute_52\" -gencode=arch=compute_50,code=\"sm_50,compute_50\" -I/usr/local/cuda/include -I. -O3 -Xcompiler -Wall  --ptxas-options="-v" --maxrregcount=128 -o heavy/heavy.o -c heavy/heavy.cu
nvcc fatal   : Unsupported gpu architecture 'compute_52'
make[2]: *** [heavy/heavy.o] Error 1

i'm using GTX 750Ti card and

Code:

nvcc -V

Thanks

You should also be compiling with the script ./build.sh included in the repo. It adds the correct compiler flags to produce a higher performance binary.

Quote from: hashbrown9000 on September 10, 2015, 04:27:26 AM i've stayed with older nvidia drivers because my system is stable. can anyone that is running the newest drivers under linux tell me if nvidia-settings works over SSH? that was one big failure of the older drivers. all configuration of setup and overclocking had to be done locally with a monitor attached, and then the rig could be deployed headless. My rig was configured over ssh completely headless.

Yeps. On Windows it is extremely simple to set fixed clocks, fans, overclocking, so you can easily have a "benchmark platform". With a headless Linux system I don't think there's any solution for fixed fans yet, others might know differently. I previously had fixed fans and clocks on Linux, but I perfectly recall that I specifically had to configure/attach a monitor in order to get that working at the time. to set the fan on linux just test this https://gist.github.com/squadbox/e5b5f7bcd86259d627ed Thanks, but I fear it needs a monitor or the x session will not start... Or will it? NOT ANY MORE-- If you have one of the latest driver packages, you can use nvidia-config to enable cards without monitors to be adjusted: "sudo nvidia-xconfig -a --cool-bits=28 --allow-empty-initial-configuration" (Source: https://bitcointalk.org/index.php?topic=826901.msg12279696#msg12279696) The numbeer "28" is a bitsum that signifies clocks, fanspeed, and power controls. This was in this thread, earlier. I think that "-a" and the longer "--allow-empty-initial-configuration" are equivalent. --scryptr -a is equivalent to --enable-all-gpus, which configures an X screen on every GPU in the system. I've tested the sctipt on Ubuntu 14.04 with two 750 Ti. To set fixed fan speeds Code: sudo ./cool_gpu2.sh 72 To reset to default Code: sudo ./cool_gpu2.sh stop

I wrote a script to manually control fan speeds on headless linux boxes. It's adapted from another source online, but modified for newer drivers. https://gist.github.com/squadbox/e5b5f7bcd86259d627ed The script can be called after using the coolbits flag as dominuspro mentioned a couple of posts ago to set up X. You could use the same format and adapt it to manually Over/Underclock or Over/Undervolt cards on linux using: Code: GPUGraphicsClockOffset[0] GPUMemoryTransferRateOffset[0] GPUOverVoltageOffset where the number in square brackets is the performance level. I haven't yet used it to adjust OC.

Quote from: scryptr on January 10, 2015, 01:25:41 AM I am still running v26, which appears very stable. It went over 4000 accepts on each rig with less than 1% rejects. --scryptr I agree, v26 was also very stable for me. 11540 +/- 50 khash/s, accepted: 11422/11476 (99.53%) for two EVGA 750Ti SCs. I just built v28. A little improvement for Quark, 11680 +/- 50 khash/s.

When you made the r26 commit (86dd73f) and updated the version numbers in `cpuminer-config.h` it only reflects this change for windows builds. The first line of `configure.ac` needs to also be changed for linux builds.

I get about 5550 +/- 50 khash/s reported from the miner itself. Yaamp takes 3.9% in fee and the rest is rejects or? I say effective hashrate as opposed to "actual" hashrate. Rejects are low. It's just a matter of how hashrates are calculated by the pool. Multipool explains it well: "The hashrate your miner displays is its own internal hashrate for calculating difficulty 1 shares, and thus is fairly meaningless to the pool. The pool displays an average hashrate calculated based on your valid, accepted shares per minute." 5250/5550 = ~95% which isn't bad considering it's connected through a stratum proxy for leasing.

Make sure that you build from the github version that is tagged with the "release 24" changeset. Commits before the tagged release could have sideeffects. And commits after are not tested properly and could have errors. Yesterday I fixed a bug when running benchmarkmode (Run the benchmark for a while and it starts to print 100 times as much text to the commandline). Seems to work, but untested on the pool. I was building from the most recent commit (the benchmark fix), not the tagged one. I'll checkout the proper one and report back.

- Fixed some of the random crashes.(ctrl-c exit and network disconnects)
- Blake rewrite to uint2. Faster x11,x13,x14,x15,x17,nist5,quark etc (around 40khash on the 980(x11))
- fixed dropping hashrate on some pools
- less gputhreads,more speed (1 watt less powerusage 750ti)

My 6card rig on the attic is using 207 watt total. (750ti).
This is including cpu and harddrive.(mining quark) 32MHASH base clocks.

SP, I saw in git that you made a commit (9d20be0) updating version numbers in cpuminer-config.h, but I noticed that it wasn't reflected in ccminer once I built it myself (Ubuntu 14.04). I did some searching and saw that the version number should be updated in configure.ac on line 1 and in cpu-miner.c on line 1536. All this lead me to another question. Does including cpuminer-config.h in the repo have any purpose? Running ./configure.sh overwrites it anyway.

SP, would you kindly add a tag in git when you release a beta? It's hard to know if i'm on the release commit or building from an in between version.

Quote from: Philley on September 22, 2014, 10:32:10 PM Hi first of all thanks for your great work here ! I'm having a little problem while configuring your tool. I used this guide: https://litecointalk.org/index.php?topic=3231.0 Everything worked for me until i try to ./configure . It says my libcurl is outdated : checking for curl-config... no checking whether libcurl is usable... no configure: error: Missing required libcurl >= 7.15.2 I searched myself but only find an OSX solution but im on linux(debian) which even with changed paths didn't work. http://stackoverflow.com/questions/16246352/how-do-i-specify-ldflags-and-cppflags-for-configure So do you have any idea how to fix that problem ? Regards Phil Running, Code: sudo apt-get install libcurl4-openssl-dev should fix it. BTW, I've found that getting CUDA and display drivers working on debian is a pain. That's why I switched to ubuntu server. I even wrote a guide. https://gist.github.com/zcshiner/4b32980792d367222304
