The specification dated 11/14/11 makes several references to a non-existent property, "CL_DEVICE_PARTITION_MAX_COMPUTE_UNITS". This probably DOES NOT intend to be "CL_DEVICE_MAX_COMPUTE_UNITS". "CL_DEVICE_MAX_COMPUTE_UNITS" must return the total number of compute units for the root device, because it is not listed as a property that may be different for a sub-device in Section 4.2. This property is probably intended to return the number of remaining compute units in the device partition.
The references are at:
Section 4.3, Table 4.4, Page 49
Section 4.3, Table 4.4, Page 50
Section 4.3, Page 51.
