Balancing CPU Processor Group Affinities
When performing 4 concurrent captures, they should be balanced across processor
arrays. For example 1, 2, 3, 4 or 5, 6, 7, 8 are balanced across affinity groups. 1, 3, 5, 7 or 2,
4, 6, 8 aren't balanced, because they are assigned the same affinity group and thus, will
saturate the resources of the CPU processor group.
On a C5 server, when you are capturing 6 10-bit sources, you should use all four SDI
ports of the first SDI card and two of the second. The last two ports of the second card
remain unused. These two unused sources should be alternating affinities to maintain
balance in the rest of the sources.
Note: CPU utilization should not exceed 75%; 60% or less is recommended.
