Detailed Description

Function Documentation

afError af_info ( )

Print diagnostic information on driver, runtime, memory, and devices.

Switch to specified device.

Requires ArrayFire Pro to index beyond first device.

Parameters

[in]	index	Index of device to select (zero-based).
[in]	use_graphics	Indicate if graphics should be enabled (default: true)
[in]	sort_mode	To sort devices based on theoretical FLOPs (sort_mode = 'f'), Memory(sort_mode = 'm'), or Compute(sort_mode = 'c'). Any other option does not sort gpus

afError af_deviceget ( int * dev )

Fetch current device index (sorted by estimated FLOPs).

Parameters

[out] dev Device index (zero-based). -1 if not yet initialized.

Translate sorted device index into real CUDA device index.

Parameters

[in]	dev	Sorted index as seen in info() (zero-based)
[out]	devreal	CUDA device index (zero-based). `-1` if not yet initialized or `dev` beyond range.

afError af_devicepush ( int index )

Save current device on stack and switch to specified device.

Parameters

[in] index Index of device to select.

afError af_devicepop ( )

Pop last device off stack and switch to it.

afError af_devicecount ( int * count )
