Member Function Documentation
◆ isPatchDisabled()
|
inline |
Is the patch disabled?
- Parameters
-
patch Patch name
- Returns
- true if the patch is disabled, false if it is either enabled or automatically decided by AQUAgpusph
◆ isPatchEnabled()
|
inline |
Is the patch enabled?
- Parameters
-
patch Patch name
- Returns
- true if the patch is enabled, false if it is either disabled or automatically decided by AQUAgpusph
Field Documentation
◆ addr_bits
| unsigned int Aqua::InputOutput::ProblemSetup::sphSettings::device::addr_bits |
Address bits of the device.
If not provided, 32 will be considered, i.e. the CL_DEVICE_ADDRESS_BITS will be queried
This field can be set with the tag Device, for instance: <Device platform="0" device="0" type="GPU" addr_bits="0" />
◆ compilation_flags
| std::string Aqua::InputOutput::ProblemSetup::sphSettings::device::compilation_flags |
Extra flags considered by this device when compiling kernels.
By default no compilation flags are considered. Note that AQUAgpusph will allways enable the compilation flag "-cl-kernel-arg-info", since it is a requirement to get it properly working
This field can be set with the tag Device, using the attributes compile_flags. For instance: <Device platform="0" device="0" type="GPU" compile_flags="-g -cl-opt-disable" />
◆ device_id
| unsigned int Aqua::InputOutput::ProblemSetup::sphSettings::device::device_id |
Index of the OpenCL device to use in the platform platform_id.
AQUAgpusph is providing the available OpenCL platforms, and the devices into them.
This field can be set with the tag Device, for instance: <Device platform="0" device="0" type="GPU" addr_bits="0" />
- Remarks
- The index of the device is refered to the available ones compatibles with the selected type device_type.
◆ device_type
| cl_device_type Aqua::InputOutput::ProblemSetup::sphSettings::device::device_type |
Type of devices that will be considered in the platform platform_id.
This field can be set with the tag Device, for instance: <Device platform="0" device="0" type="GPU" addr_bits="0" />
- See also
- device_id.
◆ patches
| std::map<std::string, int> Aqua::InputOutput::ProblemSetup::sphSettings::device::patches |
List of patchs to be forcibly enabled/disabled.
The several patches currently exist:
- nvidia_#4665567 : NVIDIA CUDA platform bug #4665567. clEnqueueMarkerWithWaitList() does not properly works
- nvidia_#9999999 : NVIDIA CUDA platform needs a synchronization point when saving files. (probably related with #4665567)
If a patch is not forcibly enabled/disabled, AQUAgpusph will automatically decide whether it is required or not.
This field can be set with the tag Device, using the attributes enable_patch and disable_patch. The patchs are separated by commas. If a patch is found simultaneously on enable_patch and disable_patch attributes, it will be disabled. For instance: <Device platform="0" device="0" type="GPU" enable_patch="nvidia_#4665567" />
◆ platform_id
| unsigned int Aqua::InputOutput::ProblemSetup::sphSettings::device::platform_id |
Index of the OpenCL platform to use.
AQUAgpusph is providing the available OpenCL platforms, and the devices into them.
This field can be set with the tag Device, for instance: <Device platform="0" device="0" type="GPU" addr_bits="0" />
