* - 4 MB
|
|
* - 16 MB
|
|
* - Uses the same process for import and export operations.

* Test source
|
|
* ------------------------
|
|
* - performance/stream/hipMemPoolImportPointer.cc
|
|
* Test requirements
|
|
* ------------------------
|
|
* - Device supports memory pools
|
|
* - HIP_VERSION >= 5.2
