             Summary: Switch to fixed-point for resources
                 Key: MESOS-3997
                 URL: https://issues.apache.org/jira/browse/MESOS-3997
             Project: Mesos
          Issue Type: Improvement
          Components: allocation, master
            Reporter: Neil Conway


Using floating point for resources is problematic, because roundoff and 
precision errors when doing resource math can produce unexpected results.

Instead, we should probably adopt a fixed-point representation: e.g., CPU 
resources will be measured as an integer number of fractional CPUs (e.g., 25 
deci-CPUs == 2.5 CPUs).
