The paper presents an evaluation method of high performance computing (HPC) systems using multicriteria efficiency analysis. The Data Envelopment Analysis approach was applied and adapted to the specifics of HPC, which enabled us to compare relative efficiency of systems considering simultaneously multiple parameters. The analysis is based on the TOP500 list of world largest supercomputers and their parameters such as: the number of cores, theoretical performance, experimental performance and power consumption. Two complementary evaluations were performed with the following goals: find currently most efficient machines and compare time-dependent efficiency changes. Using the proposed method, experimental analysis was performed for a subset of one hundred machines and five year time window. Results show improvement in efficiency during recent years and significant importance of co-processor and graphical accelerators.
