----------------------------------
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).
