Typedef Documentation

typedef struct prt_device_s prt_device_t

VSA's accelerator device. Represents a hardware accelerator. Currently synonymous with an Nvidia GPU.

"finished" is a one-directional synchronization variable. Therefore declered volatile, but no need for atomic access.

Function Documentation

void prt_device_cycle

(

prt_device_t *

device)

Implements device processing cycle.

Parameters

device

– The device to cycle.

Definition at line 67 of file prt_device.c.

void prt_device_delete

(

prt_device_t *

device)

Destroys a device.

Parameters

device

– The device to destroy.

Definition at line 49 of file prt_device.c.

prt_device_t* prt_device_new	(	int	rank,
		int	accelerator,
		int	agent_rank
	)

Creates a new device.

Parameters

rank	– The local rank of the device.
accelerator	– The global rank of the device.
agent_rank	– The rank of the communication agent.

Returns

A new device object.
