The Configuration

grunt.initConfig({
    parallel: {
      mix: {
        tasks: [{
          grunt: true,
          args: ['fast']
        }, {
          grunt: true,
          args: ['block']
        }, {
          cmd: 'pwd'
        },{
          grunt: true,
          args: ['fast']
       }]
      },
      shell: {
        tasks: [{
          cmd: 'whoami'
        }]
      },
      grunt: {
        grunt: true,
        tasks: ['fast', 'block', 'fast']
      }
    }
  });

Example

Settings

tasks - An array of commands to run, each deferred to: http://gruntjs.com/api/grunt.util#grunt.util.spawn

grunt.initConfig({
  parallel: {
    assets: {
      tasks: [{
        grunt: true,
        args: ['requirejs']
      }, {
        grunt: true,
        args: ['compass']
      },{
        cmd: 'some-custom-shell-script.sh'
      }]
    }
  }
});

Only Using Grunt

If you are only going to delegate to other grunt tasks you can simply put grunt: true in your tasks configuration and grunt-parallel will run them all using grunt.

grunt.initConfig({
  parallel: {
    assets: {
      grunt: true,
      tasks: ['fast', 'block', 'fast']
    }
  }
});

One might target the task using grunt parallel:assets. This would run compass, requirejs, and a custom shell script at the same time, each logging to your console when they are done.
