Check and fix if necessary that the Polaris app_run can implement the binding settings described in the ALCF docs:

Strategy: use the setting of CUDA_VISIBLE_DEVICES to set the cpu_bind option. This will be the default when GPUs are used.

A few notes:

  • We should use self._node_spec.cpu_ids[0] to make the assignment in order to be consistent with the node spec
  • The number of cpus for Polaris is set incorrectly to 64 in the compute node for the platform, fix this
  • We should create a tester for _build_cmdline
