Matlab 2017b I have an java exception error:
at com.mathworks.toolbox.distcomp.ui.model.ParallelSettings.convertDoubleToInt(ParallelSettings.java:290) at com.mathworks.toolbox.distcomp.ui.model.ParallelSettings.getFactoryIdleTimeout(ParallelSettings.java:188)
Before I had an error with getPreferredNumWorkers and solved it by defining PreferredNumWorkers setting in parallel.settings file in client section. What is the name of the parameter needed in this situation?
here is my parallel.settins contents
