How to debug MPJExpress locally in IntelliJ IDEA

Question

For eclipse there is an extension available to set debug configurations for MPJExpress. How I can debug an application locally in IntelliJ IDEA. I've tried to set up debugging using vm options in run/debug configurations. With this configuration I get message given below and breakpoint does not get a hit.

MPJ Express (0.44) is started in the multicore configuration

Listening for transport dt_socket at address: 8001

vm options are

-jar $MPJ_HOME$\lib\starter.jar com.owiSoft.Lab6.HelloMPJ -np 4 -device niodev -debug 8001

Answer 1

I was able to debug this MPJExpress application by modifying vm optios from

-jar $MPJ_HOME$\lib\starter.jar com.owiSoft.Lab6.HelloMPJ -np 4 -device niodev -debug 8001

to

-jar $MPJ_HOME$\lib\starter.jar com.owiSoft.Lab6.HelloMPJ -np 4 -debug 8000

And added another Remote configuration from Run/Debug Configurations menu

Then started Main configuration, kept it running and switched to RemoteDebugger configuration and started it. Following these steps breakpoint got a hit
