Gets the VM Status.
uint8_t get_status (queue& exec_queue );
get_status supports the following devices: Host, CPU, and GPU.
The get_status function gets the VM status.
The global VM Status is a single value and it accumulates via bitwise OR ( | ) all computational errors that happen inside VM functions. The following table lists the possible error values.
Status | Description |
---|---|
Successful Execution | |
status::success | VM function execution completed successfully |
status::not_defined | VM status not defined |
Warnings | |
status::accuracy_warning | VM function execution completed successfully in a different accuracy mode |
Computational Errors | |
status::errdom | Values are out of a range of definition producing invalid (QNaN) result |
status::sing | Values cause divide-by-zero (singularity) errors and produce and invalid (QNaN or Inf) result |
status::overflow | An overflow happened during the calculation process |
status::underflow | An underflow happened during the calculation process |
The queue where the routine should be executed.
Specifies the VM status.
uint8_t err = get_status (exec_queue);
if (err & status::errdom)
{
std::cout << ”Errdom status returned” << std::endl;
}
if (err & status::sing)
{
std::cout << ”Singularity status returned” << std::endl;
}
