get_status
Gets the VM Status.
Description
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 |
API
Syntax
uint8_t get_status (queue& exec_queue )
get_status supports the following devices: CPU and GPU.
Input Parameters
- exec_queue
-
The queue where the routine should be executed.
Output Parameters
- return value (status)
-
Specifies the VM status.
Examples
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; }
