Key words: Supercomputer workload stochastic modeling stability dimension reduction CRAN R. |
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. © Petrozavodsk State University |
