OPAL-如何配置项目的属性

Question

当我运行分析( OPAL源代码中的eg.CHADemo)时，我总是收到警告

[warn][OPAL] the property org.opalj.threads.CPUBoundTasks is unspecified

在former question中，它建议在/src/main/resources/ference.conf下的公共项目中的配置文件。因此，我尝试在文件中添加以下行，但仍然收到相同的警告。

org.opalj.threads{
    CPUBoundTasks = "8"
    IOBoundTasks = "8"
}

此外，在我的项目中导入OPAL作为库，并尝试在我的项目的“/src/main/ reference.conf /”中创建。我也遇到过同样的问题。

这些值是在项目编译时考虑的配置值中配置的。您需要的文件位于OPALs根目录中。当您打开文件local.sbt.template时，您将看到以下内容：

//
// Optional configuration settings specific to each developers machine.
//

// If your CPU uses hyperthreading, it is recommended to specify the
// number of physical cores and the number of hyperthreaded cores;
// this will spead up the overall execution.
   javaOptions in ThisBuild ++= Seq(
 "-Dorg.opalj.threads.CPUBoundTasks=16", // Number of physical (not            hyperthreaded) cores/CPUs
 "-Dorg.opalj.threads.IOBoundTasks=32" // Number of (hyperthreaded) cores * 1,5
)

// If you want to disable assertions, uncomment the following line.
// Assertions are heavily used throughout OPAL and have a
// signifcant performance impact. However, at development time it is
// HIGHLY recommend to turn on assertions!
//scalacOptions in ThisBuild += "-Xdisable-assertions"

//
//scalacOptions in ThisBuild -= "-Ywarn-unused-import"
//scalacOptions in ThisBuild -= "-Ywarn-unused"

如果要配置已使用核心的数量，请从文件名中删除.template，并根据需要调整值。那你就得重建欧泊。
