Summary: A multi-server model with simultaneous service and concurrent server release is considered. A stability condition of the model (under exponential assumptions) is presented. A method for fast evaluation of the stability criterion is obtained. The condition allows to verify the stability of a supercomputer at design time, provided that the governing sequence of tasks is known beforehand. The hpcwld package that provides R functions for the workload (unfinished work) evaluation as well as stability condition evaluation is discussed. The package can be obtained via Comprehensive R Archive Network. The results may be of practical interest to the designers and owners of supercomputers.
