The main performance metric used to rank the supercomputers is GTEPS (giga- traversed edges per second).
Richard Murphy from Sandia National Laboratories, says that "The Graph500's goal is to promote awareness of complex data problems", instead of focusing on computer benchmarks like HPL (High Performance Linpack), which TOP500 is based on.
[2] The algorithm and implementation that won the championship is published in the paper titled "Extreme scale breadth-first search on supercomputers".
The benchmark used in Graph500 stresses the communication subsystem of the system, instead of counting double precision floating-point.
[6] According to June 2024 release of the list, for the BFS results section, Fugaku ranks highest, but in the SSSP results section Wuhan Supercomputer ranks highest, then Pengcheng Cloudbrain-II, then Fugaku; table shows for BFS results:[7] Spain (Barcelona), has a new supercomputer MareNostrum 5 ACC, ranked 8th.
