Question "Load Average" vs "virtual processor"

Hi,

I have one question regarding the understanding of “load average” in a platform with virtual processors.

Suppose in this situation:

Total number of physical processors: 1
Number of virtual processors: 32
Total number of cores: 4
Number of cores per physical processor: 4 Number of hardware threads (strands or vCPUs) per core: 8

In the load average, does 32 indicates a full load? Or it is 4 represents a full load?

Many thanks,
MDING

If your processes are all CPU bound, which is rare, 4 would be a full load. Otherwise, the full load would be somewhere between 4 and 32.
