By default, MATLAB®
Coder™ generates code that can run the parfor-loop on multiple
threads. To treat the parfor-loops as for-loops that run on a single
thread, disable parfor with one of these methods:
By using the codegen function
with -O disable:openmp option at the command line.
By using a code generation configuration object with the property
EnableOpenMP set to false. For
example:
cfg = coder.config('lib'); cfg.EnableOpenMP = false; codegen myFunction -config cfg
By setting Enable OpenMP library if possible to No under All
Settings tab in the project settings dialog box.
Disable parfor if you want to:
Compare the execution times of the serial and parallel versions of the generated code.
Investigate failures. If the parallel version of the
generated code fails, disable parfor and generate
a serial version to facilitate debugging.
Use C compilers that do not support OpenMP.
