这些值在项目编译时考虑的配置值中配置。您需要的文件位于 OPAL 根目录中。当您打开文件时,local.sbt.template
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"
如果要配置使用的内核数,请从文件名中删除 .template 并根据需要调整值。然后你必须重建 OPAL。
