-------------------------------------
Summary: Introduce Resource Resolution
Key: MESOS-3341
URL: https://issues.apache.org/jira/browse/MESOS-3341
Project: Mesos
Issue Type: Improvement
Reporter: Jessica Hartog
Priority: Minor
After MESOS-1807, Mesos containers require >= 0.01 CPU resources and >= 32MB
Memory resources. In order to simplify accounting, Mesos should introduce
resource resolution.
For example, it is possible to launch a task with 1.0000000000001 CPU (as it
exceeds the minimum number of CPUs and is therefore considered valid). The
fractional component of this task does not benefit the running process, and can
introduce floating point errors when Mesos is accounting its offers (which we
have already seen happening in MESOS-1867 and MESOS-2635). A solution to this
could be disallowing tasks with finer granularity than the required resolution.
