MultiProcessingParams Object (IMultiProcessingParams Interface)

This object provides access to the parameters of multiprocessing and multiple CPU cores usage. The main parameter which defines whether multiprocessing is to be used is the MultiProcessingMode property. All other properties regulate the number of processes and CPU cores and are taken into account only if the MultiProcessingMode property is set to MPM_Auto or MPM_Parallel.

Name Type Description
Application Engine, read-only Returns the Engine object.
MultiProcessingMode MultiProcessingModeEnum

Specifies whether ABBYY FineReader Engine should distribute processing of multi-page documents to CPU cores. The maximum number of processes which can be run is limited by the RecognitionProcessesCount property.

By default, the property is set to MPM_Auto.

ProcessPdfInOneThread VARIANT_BOOL This property is deprecated and will be deleted in future versions.
RecognitionProcessesCount int

Specifies the maximum number of processes which can be run simultaneously.

By default, this property is 0 which means that the number of processes will be equal to the minimum of the following values:

  • number of available CPU cores,
  • number of free CPU cores available in the license,
  • number of pages in the document which is being processed.

If you change the value of this property, ABBYY FineReader Engine immediately allocates CPU cores of the license and loads the FineReader Engine Processor module. If the value of this property is 0, CPU cores allocation and loading of the FineReader Engine Processor module will be performed when it is necessary.

SharedCPUCoresMask __int64

Specifies the physical CPU cores which can be used in shared mode of CPU cores usage, as an affinity mask. Note that only physical CPU cores are masked, but not logical. The property makes sense only if CPU cores are used in shared mode (the IsSharedCPUCoresMode parameter of the InitializeEngine function was set to TRUE during initialization).

By default, all detected CPU cores are used.

UseOnlyPhysicalCPUCores VARIANT_BOOL The value of this property is ignored in ABBYY FineReader Engine for Linux.
