Module hosts

source code

List of cluster computers. Each host must be accessible via ssh w/o password:

 nodes_* .. lists with one entry per computer
 cpus_*  .. lists with one entry per CPU (usually that's the one used)

 nodes/cpus_own   .. computers reserved for own use, highest priority
 nodes/cpus_shared.. computers shared with others, medium priority
 nodes/cpus_other .. computers mainly used by others, lowest priority

 nodes/cpus_all   .. all computers in descending priority
 nice_dic         .. nice value for each host
