For creating a Graal VM JDK, the file jre\lib\jvm.cfg has to be modified such that it includes the line: -graal KNOWN Before running the Graal VM, the following environment variables is needed: - MAXINE: Pointing to a Maxine VM repository with compiled Java files. In particular, the VM will look for the compiled Java files in the following directories: ${MAXINE}/com.oracle.max.cri/bin ${MAXINE}/com.oracle.max.base/bin ${MAXINE}/com.oracle.max.asmdis/bin ${MAXINE}/com.oracle.max.asm/bin ${MAXINE}/com.oracle.max.graal.graph/bin ${MAXINE}/com.oracle.max.graal.compiler/bin ${MAXINE}/com.oracle.max.graal.nodes/bin ${MAXINE}/com.oracle.max.graal.extensions/bin ${MAXINE}/com.oracle.max.graal.runtime/bin ${MAXINE}/com.oracle.max.graal.graphviz/bin For starting the Graal VM, the flag "-graal" has to be specified. Additional flags that might be useful: -G:Plot Sends the graphs of compiled methods via network stream to the IdealGraphVisualizer (NetBeans project at ${GRAAL}/src/share/tools/IdealGraphVisualizer that can be built and run with NetBeans 7.0, use "Graal Coloring" and "Graal Edge Coloring" filters) -G:Time Prints timings for the different compilation phases -G:Meter Prints metrics for the different compilation phases The usual HotSpot flags -Xcomp -XX:CompileOnly= -XX:CompileCommand= or -XX:+PrintCompilation can be used to control the compiled methods.
