摘要：
This article concentrates on recent work on benchmarking collective operations with SKaMPI. The goal of the SKaMPI project is the creation of a database containing performance measurements of parallel computers in terms of MPI operations. Its data support software developers in creating portable and fast programs. Existing algorithms for measuring the timing of collective operations are discussed and a new algorithm is presented, taking into account the differences of local clocks. Results of measurements on the HLRS Cray T3E/900 are presented and compared with other machines.
