Hi, Martin here from GarageFarm.NET.

I have tried your new benchmark utility and noticed an issue that the benchmark won't run on a multi socket setup.

We have nodes with E5-4669v4 CPUs which can be run in 3 configurations: 1CPU, 2CPU, 4CPU. I can run the benchmark without issues on 1CPU setup, but not on 2CPU or 4CPU.

I launched Blender Benchmark from command line and here's the error log:

location: <unknown location>:-1
Traceback (most recent call last):
  File "P:\blender\blender-benchmark-1.0beta-windows64\2.80\scripts\benchmark\benchmark\space\__init__.py", line 602, in draw

  File "P:\blender\blender-benchmark-1.0beta-windows64\2.80\scripts\benchmark\benchmark\space\__init__.py", line 413, in system_info_get
    info = system_info.gatherSystemInfo(ctx)
  File "P:\blender\blender-benchmark-1.0beta-windows64\2.80\scripts\benchmark\benchmark\foundation\system_info.py", line 111, in gatherSystemInfo
    system_info["num_cpu_cores"] = int(cpu_topology['num_physical_cores'])
ValueError: invalid literal for int() with base 10: '22\r\r\n\r\r\n\r\r\nNumberOfCores'

It is a problem with reading the number of cores. I was able to launch the benchmark after editing file system_info.py and setting fixed number of cores in that line (22 in our case).

if changed in the script manually to the right value, all works fine:

file: system_info.py

system_info['cpu_brand'] = cpu_info['brand']

  system_info["num_cpu_threads"] = 32
  system_info["num_cpu_sockets"] = 2
  system_info["num_cpu_cores"] = 8

if changed in the script manually to the right value, all works fine: file: system_info.py system_info['cpu_brand'] = cpu_info['brand'] ``` system_info["num_cpu_threads"] = 32 system_info["num_cpu_sockets"] = 2 system_info["num_cpu_cores"] = 8

This should be fixed with the new version of the launcher available at https://opendata.blender.org/. Closing for now, feel free to reopen if problem persists.
