-Dcom.ibm.gpu.enable
Restriction: This system property is supported only on Java™ 11 and later.
Use this system property to control the type of processing that can be offloaded to a graphics processing unit (GPU) when processing requirements meet a specific threshold. This feature can improve the performance of certain Java functions.
Syntax
-Dcom.ibm.gpu.enable=[all|sort]
| Setting | Effect |
|---|---|
| all | Turns on GPU processing for all possible Java functions. |
| sort | Turns on GPU processing only for the Java sort() function. |
By default, this property is not set.
Explanation
Because establishing and completing communication with a GPU incurs an additional overhead, not all processing requirements benefit from being offloaded to the GPU. When set, this property enables GPU processing for any array that meets a minimum size.
