I'm trying to build TensorFlow-2.4.1-fosscuda-2020b.eb on a GPU-equipped
node using the latest EB 4.3.4, and I get this warning:
(lines deleted)
== installing extension TensorFlow 2.4.1 (28/28)...
== configuring...
WARNING: No CUDA compute capabilities specified, so using TensorFlow default
(which may not be optimal for your system).
You should use the --cuda-compute-capabilities configuration option or the
cuda_compute_capabilities easyconfig parameter to specify a list of CUDA
compute capabilities to compile with.
So I'm trying to find out the meaning and use of
"--cuda-compute-capabilities", and the documentation at
https://docs.easybuild.io/en/latest/version-specific/help.html says:
--cuda-compute-capabilities=CUDA-COMPUTE-CAPABILITIES List of CUDA compute
capabilities to use when building GPU software; values should be specified as
digits separated by a dot, for example: 3.5,5.0,7.2 (type comma-separated list)
This makes me none the wiser! Can anyone tell me what these numeric
values are supposed to mean, and how I pick the right values for the GPUs
in my nodes?
Thanks,
Ole
