Affinity Scheduling Policies

Table 1 describes the resource utilization rules of the A200T A3 Box8 SuperPoD Server.

**Table 1** Affinity policies
Priority	Policy Name	Policy Description
1	Full node occupation	A node with fewer processors indicates a higher priority. NOTE: When a distributed job is delivered, the job does not fully occupy a node as the full priority scheduling principle required. Description: Symptom: For the A200T A3 Box8 SuperPoD Server, if two-processor and 14-processor jobs are scheduled at the same time, the two jobs are not scheduled to the same node. Cause analysis: After Volcano schedules a job, there is a delay for Ascend Device Plugin to report the scheduled Ascend AI Processor topology to mindx-dl-deviceinfo-$*{node_name}*. As a result, Volcano fails to verify the number of Ascend AI Processors on a node and the job is scheduled to another node.
