/// <item><see cref="AffinityDomain.Numa"/> - Split the device into sub-devices comprised of compute units that share a NUMA node.</item>
/// <item><see cref="AffinityDomain.L4Cache"/> - Split the device into sub-devices comprised of compute units that share a level 4 data cache.</item>
/// <item><see cref="AffinityDomain.L3Cache"/> - Split the device into sub-devices comprised of compute units that share a level 3 data cache.</item>
/// <item><see cref="AffinityDomain.L2Cache"/> - Split the device into sub-devices comprised of compute units that share a level 2 data cache.</item>
/// <item><see cref="AffinityDomain.L1Cache"/> - Split the device into sub-devices comprised of compute units that share a level 1 data cache.</item>
/// <item><see cref="AffinityDomain.NextPartitionable"/> - Split the device along the next partitionable affinity domain. The implementation shall find the first level along which the device or sub-device may be further subdivided in the order NUMA, L4, L3, L2, L1, and partition the device into sub-devices comprised of compute units that share memory subsystems at this level.</item>
