Detailed Description
A class that can be used to determine or modify which device adapter VTK-m algorithms should be run on.
This class captures the state of the per-thread device adapter and will revert any changes applied during its lifetime on destruction.
Constructor & Destructor Documentation
◆ ScopedRuntimeDeviceTracker() [1/3]
| VTKM_CONT vtkm::cont::ScopedRuntimeDeviceTracker::ScopedRuntimeDeviceTracker | ( | vtkm::cont::DeviceAdapterId | device, |
| RuntimeDeviceTrackerMode | mode = RuntimeDeviceTrackerMode::Force |
||
| ) |
Construct a ScopedRuntimeDeviceTracker where the state of the active devices for the current thread are determined by the parameters to the constructor.
'Force'
- Force-Enable the provided single device adapter
- Force-Enable all device adapters when using vtkm::cont::DeviceAdaterTagAny 'Enable'
- Enable the provided single device adapter if it was previously disabled
- Enable all device adapters that are currently disabled when using vtkm::cont::DeviceAdaterTagAny 'Disable'
- Disable the provided single device adapter
- Disable all device adapters when using vtkm::cont::DeviceAdaterTagAny
Constructor is not thread safe
◆ ScopedRuntimeDeviceTracker() [2/3]
| VTKM_CONT vtkm::cont::ScopedRuntimeDeviceTracker::ScopedRuntimeDeviceTracker | ( | vtkm::cont::DeviceAdapterId | device, |
| RuntimeDeviceTrackerMode | mode, | ||
| const vtkm::cont::RuntimeDeviceTracker & | tracker | ||
| ) |
Construct a ScopedRuntimeDeviceTracker associated with the thread associated with the provided tracker.
The active devices for the current thread are determined by the parameters to the constructor.
'Force'
- Force-Enable the provided single device adapter
- Force-Enable all device adapters when using vtkm::cont::DeviceAdaterTagAny 'Enable'
- Enable the provided single device adapter if it was previously disabled
- Enable all device adapters that are currently disabled when using vtkm::cont::DeviceAdaterTagAny 'Disable'
- Disable the provided single device adapter
- Disable all device adapters when using vtkm::cont::DeviceAdaterTagAny
Any modifications to the ScopedRuntimeDeviceTracker will effect what ever thread the tracker is associated with, which might not be the thread which ScopedRuntimeDeviceTracker was constructed on.
Constructor is not thread safe
◆ ScopedRuntimeDeviceTracker() [3/3]
| VTKM_CONT vtkm::cont::ScopedRuntimeDeviceTracker::ScopedRuntimeDeviceTracker | ( | const vtkm::cont::RuntimeDeviceTracker & | tracker | ) |
Construct a ScopedRuntimeDeviceTracker associated with the thread associated with the provided tracker.
Any modifications to the ScopedRuntimeDeviceTracker will effect what ever thread the tracker is associated with, which might not be the thread which ScopedRuntimeDeviceTracker was constructed on.
Constructor is not thread safe
