1 Datagrid in Earth System Sciences (DGESS) - Benchmarks - Projektreffen am Max-Planck-Institut für Meteorologie Heinrich Widmann 28. November 2005

2 Allgemeines Gute Benchmarktools ? UNIX-Kommando 'time' ! Gibt's was besseres ? Was soll/muss getestet werden ? CPU Datenreduktion Resourcenverbrauch (Memory,...) Erste Resultate

3 gCCDAS : Performance-Test : local versus grid (executable hesscol)

4 Datentransfer (Durchsatz mit versch. Methoden) Sun Grid Engine NFS Linux workstations: 3.0 Ghz Intel 1 GB memory Tests: - a) 1 WS local disc - b) 1 WS NFS read/write - c) SGE : 10 workernodes NFS read/write

5 Performance of afterburner

6 Datentransfer : RepliCator (erste Benchmarkresults) 1,6 X Speedup (est.) 0:38,13:53Repli. (est. pipelining) 0:38,10:42RepliCator (no pipelining) 0:40,56:13NFS xfr CPU TimeWall Clock 230MB input data set 225MB output data set Kurs10 acting as Fileserver Kurs1-9 as Executionnodeds

7 CDOs : CPU and Datenreduktion cdo selcode, rawfile outfile rawfile : beinh. 101 codes und hat 107 MB
