|
|
* fails to launch, execute_1_3 must immediately invoke the callback with

|
|
*
|
|
* When the asynchronous task has finished its execution, it must
|
|
* immediately invoke the callback object provided as an input to the
|
|
* execute_1_3 function. This callback must be provided with the ErrorStatus of
|
|
* the execution.
|
|
*
|
|
* If the launch is successful, the caller must not change the content of
|
|
* any data object referenced by 'request' (described by the
|
|
* {@link @1.0::DataLocation} of a {@link @1.0::RequestArgument}) until the
|
|

|
|
* must not change the content of any of the data objects corresponding to

|
|
*
|
|
* If the prepared model was prepared from a model wherein all tensor
|
|
* operands have fully specified dimensions, and the inputs to the function
|
|
* are valid, then:
|
|
* - the execution should launch successfully (ErrorStatus::NONE): There
|
|
* must be no failure unless the device itself is in a bad state.
|
|
* - if at execution time every operation's input operands have legal
|
|
* values, the execution should complete successfully (ErrorStatus::NONE):

|
|
* to the execute_1_3 function to the time the driver invokes
|
|
* the callback.
|

* @param deadline The time by which the execution is expected to complete.

|
|
* execution may be aborted.

|
|
* executing a {@link OperationType::WHILE}
|
|
* operation. If a loop condition model does not
|
|
