Function Documentation

fill_array()

template<typename value_type , typename size_type >

__global__ void plssvm::hip::detail::fill_array	(	value_type *	data,
		value_type	value,
		size_type	pos,
		size_type	count
	)

Fill the array data with count values value starting at position pos.

Template Parameters

value_type	the type of the array
size_type	the unsigned size_type

Parameters

[in,out]	data	the array to fill
[in]	value	the value to fill the array with
[in]	pos	the position at which to start te filling
[in]	count	the number of values to fill in the array starting at pos

gpu_assert()

void plssvm::hip::detail::gpu_assert

(

hipError_t

code

)

Check the HIP error code. If code signals an error, throw a plssvm::hip::backend_exception.

The exception contains the following message: "HIP assert 'HIP_ERROR_NAME' (HIP_ERROR_CODE): HIP_ERROR_STRING".

Parameters

[in]

code

the HIP error code to check

Exceptions

plssvm::hip::backend_exception

if the error code signals a failure

get_device_count()

int plssvm::hip::detail::get_device_count

(

)

Returns the number of available HIP devices.

Returns

the number of devices ([[nodiscard]])

set_device()

void plssvm::hip::detail::set_device

(

int

device

)

Set the device to the active HIP device.

Parameters

[in]

device

the now active device

Exceptions

plssvm::hip::backend_exception

if the given device ID is smaller than 0 or greater or equal than the available number of devices

device_synchronize()

void plssvm::hip::detail::device_synchronize

(

int

device

)

Wait for the compute device to finish.

Calls plssvm::hip::detail::peek_at_last_error() before synchronizing.

Parameters

[in]

device

the HIP device to synchronize

Exceptions

plssvm::hip::backend_exception

if the given device ID is smaller than 0 or greater or equal than the available number of devices
