Name

write_aop_knowledgewrite_aop_knowledgeWriteAopKnowledgeWriteAopKnowledge — Write knowledge about hardware dependent behavior of automatic operator parallelization to file.

Signature

Description

write_aop_knowledgewrite_aop_knowledgeWriteAopKnowledgeWriteAopKnowledgeWriteAopKnowledge stores the automatic parallelization knowledge of HALCON operators to file. The knowledge hold by the HALCON system is used to better utilize multiprocessor hardware in order to speed up the processing of operators. To optimize the automatic parallelization of operators, HALCON needs some specific knowledge about the speed of operators on the used hardware. This hardware-specific knowledge can be obtained by calling the operator optimize_aopoptimize_aopOptimizeAopOptimizeAopOptimizeAop or read from file by using read_aop_knowledgeread_aop_knowledgeReadAopKnowledgeReadAopKnowledgeReadAopKnowledge, respectively.

With write_aop_knowledgewrite_aop_knowledgeWriteAopKnowledgeWriteAopKnowledgeWriteAopKnowledge it is possible to store this knowledge explicitly in a binary file. At this, FileNameFileNameFileNameFileNamefileName denotes the name of this file (incl. path and file extension). If an empty string ''"""""""" is passed to FileNameFileNameFileNameFileNamefileName, HALCON writes the knowledge to the specific file '.aop_info'".aop_info"".aop_info"".aop_info"".aop_info" in the HALCON installation directory (Linux/macOS) or within the common application data folder (Windows). This file is read by HALCON during the initialization phase automatically. write_aop_knowledgewrite_aop_knowledgeWriteAopKnowledgeWriteAopKnowledgeWriteAopKnowledge adds attributes to the knowledge like the host name and information about HALCON architecture, variant, version, and revision. This enables HALCON to write aop knowledge sets of different machines or HALCON systems into the same file. Therefore, write_aop_knowledgewrite_aop_knowledgeWriteAopKnowledgeWriteAopKnowledgeWriteAopKnowledge can control the updating of the files contents by a pair of values passed to GenParamNameGenParamNameGenParamNameGenParamNamegenParamName and GenParamValueGenParamValueGenParamValueGenParamValuegenParamValue. Every entry in GenParamNameGenParamNameGenParamNameGenParamNamegenParamName must have one corresponding, specifying entry in GenParamValueGenParamValueGenParamValueGenParamValuegenParamValue, meaning that the tuples passed to the parameters must have the same length. GenParamNameGenParamNameGenParamNameGenParamNamegenParamName supports the values in following list, describing the possible applicable values for GenParamValueGenParamValueGenParamValueGenParamValuegenParamValue:

'mode'"mode""mode""mode""mode"

sets the way how existing knowledge with same attributes would be updated in the file.

'truncate'"truncate""truncate""truncate""truncate"

for GenParamValueGenParamValueGenParamValueGenParamValuegenParamValue deletes the existing knowledge with matching attributes before the new information is added to file.

'renew'"renew""renew""renew""renew"

overwrites existing knowledge and adds new one (default).

'append'"append""append""append""append"

keeps all existing operator information and just adds the knowledge not already contained.

'nil'"nil""nil""nil""nil"

however refuses any update of the file but checks the user priviledges, i.e., if read write access is available.

'operator'"operator""operator""operator""operator"

denotes that the corresponding index value of GenParamValueGenParamValueGenParamValueGenParamValuegenParamValue contains an operator name. It delimits the storage on a dedicated operator set. Multiple definitions of operators are possible. By default, information of any operator possessing AOP optimization data is written.

'iconic_type'"iconic_type""iconic_type""iconic_type""iconic_type"

focuses on AOP information for a specific iconic type, specified by following values of GenParamValueGenParamValueGenParamValueGenParamValuegenParamValue: 'byte'"byte""byte""byte""byte",'uint2'"uint2""uint2""uint2""uint2",'real'"real""real""real""real",'int1'"int1""int1""int1""int1", 'int2'"int2""int2""int2""int2",'int4'"int4""int4""int4""int4",'int8'"int8""int8""int8""int8",'direction'"direction""direction""direction""direction", 'vector_field'"vector_field""vector_field""vector_field""vector_field",'cyclic'"cyclic""cyclic""cyclic""cyclic",ValRef{'vector_field}, 'complex'"complex""complex""complex""complex",'region'"region""region""region""region",'xld'"xld""xld""xld""xld". Multiple definitions of iconic types are possible.

Execution Information

• Multithreading type: exclusive (runs in parallel only with independent operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.

Parameters

Result

write_aop_knowledgewrite_aop_knowledgeWriteAopKnowledgeWriteAopKnowledgeWriteAopKnowledge returns 2 (H_MSG_TRUE) if all parameters are correct and the file could be read. If necessary, an exception is raised.
