Xeon Phi - Balanced vs Scatter - 64 or Less Threads

Hi All,

If the number of threads to use are 32 or any number equal or less than 64. Then, how does balance and scatter thread affinity differ from each other?

As per my analysis, these two will use same number of cores (1 thread per core). Not that balance will use 2 thread per core to keep sequential thread together, leading to only 16 cores?

Thanks.
