AMD Opteron 6234 (6200/6300 series Opteron) Bulldozer/Piledriver microarchitecture build (fail to run compiled binary 0.1.1)

[agentpatience]

These systems fail to run compiled binary using a server system of AMD 6200/6300 series QUAD Opteron processors each with 12-16 cores per processor die; depending on the blade configuration. I have 12 of these systems that I would like to bring up with djm CPUminer if possible. My first attempt failed as per a successful bring up of a intel dual 2680v4 server:

so we build CPUminer+mtp on Ubunto 18.10 Server as per:

sudo apt-get update -y sudo apt-get upgrade -y sudo reboot git clone https://github.com/zcoinofficial/cpuminer.git cd cpuminer/ chmod a+x configure chmod a+x build.sh chmod a+x autogen.sh sudo apt-get install automake autoconf pkg-config libcurl4-openssl-dev libjansson-dev libssl-dev libgmp-dev make g++ sudo apt-get install zlib1g-dev ./build.sh

When we run the binary in GDB we get:

Please help!

use larger difficulty, you need to scale your difficulty according the number of core/thread you use. The gdb info are pretty useless (my bad). I'll try to find out how to do a debug build for linux. However if you have a windows machine and msvc, the windows build of cpuminer have debug info

[agentpatience]

Thanks. I will try to test with windows install on the system with -debug option but I prefer to run miners with linux.

[djm34]

I dont mean with --debug option. I mean running it within msvc in debug mode. I have been running it since the beginning of the afternoon this way and haven't any crash yet... so I really need your input

[GeorgeAnton1]

I'm having the same issue. Was there anything I can do to help?
