This extension adds a pname:priority value specified at memory allocation
|
||
|
|
time.
|
||
|
|
On some systems with both device-local and non-device-local memory heaps,
|
||
|
|
the implementation may transparently move memory from one heap to another
|
||
|
|
when a heap becomes full (for example, when the total memory used across all
|
||
|
|
processes exceeds the size of the heap).
|
||
|
|
In such a case, this priority value may be used to determine which
|
||
|
|
allocations are more likely to remain in device-local memory.
