Description
read_aop_knowledgeread_aop_knowledgeReadAopKnowledgeReadAopKnowledgeread_aop_knowledge loads the automatic operator parallelization
(AOP) knowledge of HALCON operators from file. The knowledge is used to
better utilize multiprocessor hardware in order to speed up the processing
of operators. To optimize the automatic operator parallelization,
HALCON needs some knowledge about the speed of operators on the used
hardware. This hardware-specific knowledge
can be obtained and stored by calling the operator optimize_aopoptimize_aopOptimizeAopOptimizeAopoptimize_aop
and write_aop_knowledgewrite_aop_knowledgeWriteAopKnowledgeWriteAopKnowledgewrite_aop_knowledge, respectively.
With read_aop_knowledgeread_aop_knowledgeReadAopKnowledgeReadAopKnowledgeread_aop_knowledge, it is possible to load this knowledge
explicitly from a binary file. In doing so, FileNameFileNameFileNamefileNamefile_name denotes the
name of this file (incl. path and file extension). If an empty string
''"""""""" is passed to FileNameFileNameFileNamefileNamefile_name, HALCON reads the knowledge
from the specific file .aop_info in the HALCON installation
directory (Linux) or within the common application data folder
(Windows). This file is read by HALCON automatically during the
initialization phase but can easily be re-read by
read_aop_knowledgeread_aop_knowledgeReadAopKnowledgeReadAopKnowledgeread_aop_knowledge. The read knowledge updates the system's
parallelization information and can be controlled by pairs of additional
parameter values passed to GenParamNameGenParamNameGenParamNamegenParamNamegen_param_name and GenParamValueGenParamValueGenParamValuegenParamValuegen_param_value.
Every entry in GenParamNameGenParamNameGenParamNamegenParamNamegen_param_name must have one corresponding,
specifying entry in GenParamValueGenParamValueGenParamValuegenParamValuegen_param_value, meaning that the tuples
passed to the parameters must have the same length. GenParamNameGenParamNameGenParamNamegenParamNamegen_param_name
supports the values in following list, describing the possible applicable
values for GenParamValueGenParamValueGenParamValuegenParamValuegen_param_value:
- 'ignore_attrib'"ignore_attrib""ignore_attrib""ignore_attrib""ignore_attrib"
-
suppresses to check knowledge attributes.
E.g., while reading the file read_aop_knowledgeread_aop_knowledgeReadAopKnowledgeReadAopKnowledgeread_aop_knowledge checks whether
its content was written for the currently used computer and whether the
contained parallelization information regards the currently used HALCON
version, revision, and architecture. The attributes to suppress are
specified by passing any of the following values to
GenParamValueGenParamValueGenParamValuegenParamValuegen_param_value:
- 'host'"host""host""host""host"
the host name of the current machine
- 'cpu_info'"cpu_info""cpu_info""cpu_info""cpu_info"
the machine topology information
- 'variant'"variant""variant""variant""variant"
the HALCON variant
- 'version'"version""version""version""version"
the HALCON version
- 'revision'"revision""revision""revision""revision"
the HALCON revision
- 'architecture'"architecture""architecture""architecture""architecture"
the HALCON architecture
Multiple suppressions of attribute checks are possible.
- 'mode'"mode""mode""mode""mode"
-
sets the way how the system's information gets
updated.
- 'truncate'"truncate""truncate""truncate""truncate"
for GenParamValueGenParamValueGenParamValuegenParamValuegen_param_value deletes
all the existing information before the new knowledge loaded from file
is added.
- '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"
refuses any updates but returns the
knowledge attributes in AttributesAttributesAttributesattributesattributes and all the operators
contained in file in OperatorNamesOperatorNamesOperatorNamesoperatorNamesoperator_names.
- 'operator'"operator""operator""operator""operator"
denotes that the corresponding index value of
GenParamValueGenParamValueGenParamValuegenParamValuegen_param_value contains an operator name. Multiple definitions
of operators are possible. By default, information of any contained
operator is loaded.
- 'iconic_type'"iconic_type""iconic_type""iconic_type""iconic_type"
focuses on AOP information for a specific
iconic type, specified by following values of GenParamValueGenParamValueGenParamValuegenParamValuegen_param_value:
'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",'vector_field'"vector_field""vector_field""vector_field""vector_field",
'complex'"complex""complex""complex""complex",'region'"region""region""region""region",'xld'"xld""xld""xld""xld". Multiple definitions
of iconic types are possible.
The names of updated operators are returned in OperatorNamesOperatorNamesOperatorNamesoperatorNamesoperator_names,
the attributes of the read knowledge in AttributesAttributesAttributesattributesattributes. The latter
tuple codes the following meaning by index beginning with index 0 in
corresponding order: host name, HALCON variant, HALCON version,
HALCON revision, HALCON architecture.
Execution Information
- Multithreading type: exclusive (runs in parallel only with independent operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
