Ok, so a friend is working on his Masters and is going to do something on clusters, thus giving us an excuse to build one. :) The plan is to gather what old machines we have around and run clusterknoppix on them (nice and easy to setup). We are trying to figure out what we could actually do with it though to test the performance and such once it's running. Any suggestions? |

Been there, done that. Things to test: failover speed and reliability performance before and after failover depending on the cluster's service(s), you should test each service offered (NFS or Samba? maybe. WWW? definitely. Database? probably.) |

According to http://www.ibm.com/developerworks/linux/library/l-cluster2/i... you could test with LINPACK. http://osdir.com/ml/clustering.beowulf.general/2006-01/msg00... says slbench but it's a really old post. Just google for "Linux cluster benchmark" and see what other people used. |

Quoting:We are trying to figure out what we could actually do with it though to test the performance and such once it's running.I find dnetc from http://distributed.net pretty much sucks every last cycle out of the boxes I've tried it on. It's compute intensive, not I/O. |

ah, dnetc is still around eh?
My friend friend checked boinc and it doesn't do clusters.
I seem to recall dnetc did... Good suggestions all around so far. Thanks guys! Hopefully we'll start building in the next couple weeks (assuming life agrees with us) |
