 The number of cores per node that are currently allowed to be allocated for GPU jobs is limited
 depending on how many GPUs are being requested.
-On Alpha Centauri you may only request up to 6 cores per requested GPU.
 This is because we do not wish that GPUs become unusable due to all cores on a node being used by
 a single job which does not, at the same time, request all GPUs.
 
 E.g., if you specify `--gres=gpu:2`, your total number of cores per node (meaning:
-`ntasks`*`cpus-per-task`) may not exceed 12 (on Alpha Centauri)
+`ntasks`*`cpus-per-task`) may not exceed 12 on [`Alpha Centauri`](alpha_centauri.md).
 
 Note that this also has implications for the use of the `--exclusive` parameter.
-Since this sets the number of allocated cores to 48, you also **must** request all eight GPUs
-by specifying `--gres=gpu:8`, otherwise your job will not start.
+Since this sets the number of allocated cores to the maximum, you also **must** request all GPUs
+otherwise your job will not start.
 In the case of `--exclusive`, it won't be denied on submission,
 because this is evaluated in a later scheduling step.
 Jobs that directly request too many cores per GPU will be denied with the error message:
