In case your cluster uses a head node with one or more Intel® Xeon Phi™ coprocessors, a couple more steps have to be taken in order to collect all information.
First of all, execute the clck-collect command using your configuration file and node list.
clck-collect -a -c <your configuration file> -f <your node list>
Then create a second node list containing just the name of the head node, without any additional "role:" tag.
Now you can collect the additional information by executing
clck-collect -m miccheck -m micinfo -m offload_phi -c <your configuration file> -f <node list containing only the head node>
