Benchmark results

Starting from dev version 5.33/02 (and version 5.32/01, 5.30/06), the TProofBench steering class provides the static method GetPerfSpecs which can be used - used after a CPU benchmark - to extract some numbers giving an idea of the cluster specs.

The selector used for the measurement is ProofSimple.h,.C which can be found undertutorials/proof . The selector fills 16 histograms with 1000000*workers Gaussian random numbers. Each 'unit' corresponds, therefore, to the generation of 16 gaussian number and the filling of 16 histograms. We call this a 'random generation' and we measure the perfomance specs in RNGPS, i.e. RaNdom Generations Per Second . We measure both the maximum RNGPS provided by the PROOF cluster and the normalized, per-worker, RNGPS .

This page is supposed to collect results from cluster where the measurement has been done.
