Subject Re: Environment consideration for a research on scheduling
Date Tue, 27 Sep 2011 20:02:51 GMT
Desktop edition was chosen just to run the namemode and to monitor cluster
statistics. Workernodes were chosen to run on ubuntu server edition because
we find this configuration in several research papers. One of such
configuration can be found in the paper for LATE scheduler (is maybe some
source code of this available or is integrated in the new fair scheduler?)

thanks for the provided tools..
