dcgmReturn_t dcgmPolicyTrigger ( dcgmHandle_t pDcgmHandle )

Parameters

pDcgmHandle

IN: DCGM Handle

Returns

• DCGM_ST_OK If the call was successful
• DCGM_ST_GENERIC_ERROR The policy manager was unable to perform another iteration.

Description

Inform the policy manager loop to perform an iteration and trigger the callbacks of any registered functions. Callback functions will be called from a separate thread as the calling function.

Note: The GPU monitoring and management agent must call this method periodically if the operation mode is set to manual mode (DCGM_OPERATION_MODE_MANUAL) during initialization (dcgmInit).

dcgmReturn_t dcgmUpdateAllFields ( dcgmHandle_t pDcgmHandle, int  waitForUpdate )

waitForUpdate

IN: Whether or not to wait for the update loop to complete before returning to the caller 1=wait. 0=do not wait.

Returns

• DCGM_ST_OK if the call was successful
• DCGM_ST_BADPARAM if waitForUpdate is invalid
• DCGM_ST_GENERIC_ERROR if an unspecified DCGM error occurs

Description

This method is used to tell the DCGM module to update all the fields being watched.

Note: If the if the operation mode was set to manual mode (DCGM_OPERATION_MODE_MANUAL) during initialization (dcgmInit), this method must be caused periodically to allow field value watches the opportunity to gather samples.
