function AutoDeviceSelect(LoadFunction: TMtxNotifyEvent; CacheItemCount: Integer; CacheItemLength: Integer): TOpenCLDevice;
The function will measure time of running LoadFunction on all devices and will return the fastest device.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | LoadFunction | TMtxNotifyEvent | |
| 2 | CacheItemCount | Integer | |
| 3 | CacheItemLength | Integer |
Returns: TOpenCLDevice
Remarks:
The command queue on the fastest is marked automatically. For each device the function will be called twice and should therefore have a meaningfull computational load. The first call is for warming up the cache and waking up the device from low power mode. The second call is timed.
