Neil Conway created MESOS-3997: ---------------------------------- 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). -- This message was sent by Atlassian JIRA (v6.3.4#6332)
