Class Device

Readonlyid

ReadonlypciBusName

activate

• activate(): this

  Returns this

  Description

  Sets this device as the current device for the calling host thread.
  
  Any device memory subsequently allocated from this host thread will be physically resident on this device. Any host memory allocated from this host thread will have its lifetime associated with this device. Any streams or events created from this host thread will be associated with this device. Any kernels launched from this host thread will be executed on this device.
  
  This call may be made from any host thread, to any device, and at any time. This function will do no synchronization with the previous or new device, and should be considered a very low overhead call.

callInContext

• callInContext(work: () => any): this

  Parameters

  • work: () => any

    A function to execute

  Returns this

canAccessPeerDevice

• canAccessPeerDevice(peerDevice: Device): boolean

  Parameters

  • peerDevice: Device

  Returns boolean

  true if this Device's contexts are capable of directly accessing memory from contexts on peerDevice, otherwise false.

disablePeerAccess

• disablePeerAccess(peerDevice: Device): this

  Parameters

  • peerDevice: Device

  Returns this

enablePeerAccess

• enablePeerAccess(peerDevice: Device): this

  Parameters

  • peerDevice: Device

  Returns this

getFlags

• getFlags(): DeviceFlags

  Returns DeviceFlags

reset

• reset(): this

  Returns this

  Description

  Explicitly destroys and cleans up all resources associated with the current device in the current process. Any subsequent API call to this device will reinitialize the device.
  
  Note that this function will reset the device immediately. It is the caller's responsibility to ensure that the device is not being accessed by any other host threads from the process when this function is called.

setFlags

• setFlags(newFlags: DeviceFlags): void

  Parameters

  • newFlags: DeviceFlags

    The new flags for the device's primary context.

  Returns void

synchronize

• synchronize(): this

  Returns this

  Description

  Blocks execution of further device calls until the device has completed all preceding requested tasks.

  Throws

  an error if one of the preceding tasks has failed. If the cudaDeviceScheduleBlockingSync flag was set for this device, the host thread will block until the device has finished its work.
