E.A. Kiselev, P.N. Telegin, B.M. Shabanov
2021 arXiv   pre-print
The evolution of high-performance computing is associated with the growth of energy consumption.  ...  Often upgrade of computing resources is done step-by-step, i.e. parts of older supercomputers are removed from service and replaced with newer ones.  ...  We also plan to estimate the change in the runtime of parallel programs, taking into account the wait time in the queue for a set of computing resources at SCC.  ...
