-### Core-Hours
 
-The resources that are currently subject to accounting are the core-hours. The core-hours are accounted on the wall clock basis. The accounting runs whenever the computational cores are allocated or blocked via the PBS Pro workload manager (the qsub command), regardless of whether the cores are actually used for any calculation. 1 core-hour is defined as 1 processor core allocated for 1 hour of wall clock time. Allocating a full node (16 cores) for 1 hour accounts to 16 core-hours. See example in the  [Job submission and execution](job-submission-and-execution/) section.
