bzminer_v7.2.4_linux.tar.gz Linux Mint 19.3 (Ubuntu 18.04)

bzminer requires Nvidia driver that is too "high". Is it really necessary? Maybe that static version of miner should be distributed...

I do not use bzminer, this is my first touch. I tried it first on HiveOS but the latest bzminer was at version 7.2.3 and it was not mining at all, it was looping with core dump error; maybe my CPU (AMD AM3, some x4) was too old for bzminer, maybe that bzminer requires some super new instructions that are missing in this older CPU... So I tried it on my test PC with Linux Mint 19.3 and I see it cannot mine because it doesn't like CUDA library that is installed...

I copied libnvrtc.so.11.2.152 from HiveOS to my test PC (Linux Mint 19.3), with Intel XEON CPU. I cannot replicate the crash (core dump) so I assume that it is because binary was compiled to use some instruction that is not supported by AMD x4 610e). I cannot mine, GPU (GTX1060) is not detected.

I connect there over ssh. bzminer requires X11!! Why?? It is CLI miner, isn't it??

I can crash bzminer 7.2.4 on XEON CPU:

Summary? It looks like bzminer is not matured. Distributed binary doesn't work, it has signs of inexperienced developer, source code is not available so I cannot try to compile it from source code. GAME OVER...

hi @PSLLSP thank you for all these details

there was a bug in 7.2.3 which was unlocking nvidia clocks when bzminer started by default, that was fixed in the next version. this causes a crash on some systems like hiveos

As far as the drivers go, the cuda_tk version of bzminer is available for rigs that you do not want to update to the latest nvidia drivers

bzminer requires cuda 11.5 or higher (driver 495.29.05 or higher) bzminer cuda_tk version requires only 11.2 or higher (driver 460.27.03 or higher). if the cuda toolkit is installed though, this version can conflict with the installed cuda toolkit so the regular bzminer should be used if this is the case

The X11 display is required for nvidia driver monitoring. by default bzminer will try to use display ":0", however you can change this in the config.txt with the x_display option. In a future release i will attempt to find an available display if ":0" is not available

I already upgraded bzminer to version v7.2.5 at HiveOS and it worked with GTX1070. But I cannot get it running with older cards, like GTX1060 or GTX750Ti (on my PC). This is PC with GTX1060, bzminer is from bzminer_v7.2.5_linux_cuda_tk.tar.gz:

$ ./bzminer --devices

My GPU is working good, it works with miniZ, WildRig-multi, T-Rex and others. It is invisible for bzminer... The same applies to GTX-750Ti.

BTW, it will be nice to add support for --version/-V parameters, it is the standard...

I started with bzminer because it was the only miner with support for blake3 algo, it was few days ago. I tried hard to use it but there are many compatibility problems with my old GPUs. Once T-Rex with support for blade3 was released, I lost interest in bzminer, it doesn't work for me...
