Parameter documentation

This parameter controls the compile mode in the Virtual Machine Container (VMC). If the parameter has the value on, the methods are compiled asynchronously. During this time the application continues to run in interpreter mode. If the parameter has the value off, the compilation is performed inline, in other words the application is stopped until the compilation is completed. This parameter is only used by the "optimized backend". This means that the parameter is only effective on the following platforms: HP with IA_64 CPU. Using the addition max_vms, you can specify how many asynchronous compilations can be run simultaneously. The default here is 1.
Examples
vmcj/asyncCompilation = off --> no asynchronous compilation vmcj/asyncCompilation = on --> asynchronous compiling active, max. one asynchronous compilation at any one time vmcj/asyncCompilation = on --> asynchronous compiling active, max. three asynchronous compilations at any one time
