Hi, I installed the new OpenAIS infrastructure (cluster-2.00.00) on my cluster. Here are the results of the usual tests: == Using PLOCKS == filecount=500 iteration=0 elapsed time=10.294059 s iteration=1 elapsed time=9.416584 s iteration=2 elapsed time=10.30608 s iteration=3 elapsed time=10.294692 s iteration=4 elapsed time=10.280316 s total elapsed time=50.591731 s filecount=501 iteration=0 elapsed time=11.170378 s iteration=1 elapsed time=10.312731 s iteration=2 elapsed time=10.308767 s iteration=3 elapsed time=10.308905 s iteration=4 elapsed time=10.308703 s total elapsed time=52.409484 s == Using FLOCKS == filecount=500 iteration=0 elapsed time=5.311825 s iteration=1 elapsed time=7.030903 s iteration=2 elapsed time=5.23619 s iteration=3 elapsed time=5.229282 s iteration=4 elapsed time=5.235798 s total elapsed time=28.043998 s filecount=501 iteration=0 elapsed time=5.03941 s iteration=1 elapsed time=5.278866 s iteration=2 elapsed time=4.93929 s iteration=3 elapsed time=5.271063 s iteration=4 elapsed time=5.133244 s total elapsed time=25.661873 s The magic limit of 500 disappeared, and flocks are indeed twice as fast as plocks, something you probably expected. However, in the first test the old infrastructure was much-much faster, doing an iteration in about 0.2 s, thanks to some caching effect. This is the kind of performance I'm after. How can I tune the new infrastructure, like cache sizes in the old? Or should I look for something else? -- Thanks, Feri. -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
